Windows Presentation Foundation Terminal Server Print W has encountered a problem and needs to close. We are sorry for the inconvenience.

When connecting Remote desktop from a Windows Xp machine on to Windows Server 2008, and trying to print on a redirected printer, the print comes out fine but the error mentioned in the subject pops up. Microsoft suggests to install .Net framework 3 with Sp1 and update the file Tswpfwrp.exe. The .Net fix didnot solve the problem for any computer in my organisation, updating the Tswpfwrp.exe file did. Heres the simple procedure.

1. Copy the file Tswpfwrp.exe from any Windows Vista or Windows 7 machine located in System32 folder
2. Paste the file in System32 folder of the windows Xp machine.

Connecting to remote desktop and printing should now work without error.

Hp laserjet 1010 Windows 7 drivers

The Hp website doesnot have any drivers to install this printer. Heres an easy and quick method, as suggested on an Hp forum, works perfectly.
1. Printer and Faxes-> Add Printer
2. Local Printer attached to this computer
3. Use an existing port - DOT 4 001
4. Choose Hp laserjet 3050's driver from the list.
5. Give a test print, if it doesn't print restart the machine and it should work fine.
6. Rename the printer to Hp Laserjet 1010

The reason this works is because Laserjet 1010 requires generic PCL 5 drivers, meaning any printer's PCL 5 driver should work.

Always start an application in Administrator mode in Windows 7/ Vista. Path/file access error.

One of the users was having an issue when opening an application. He would get the error "Path/file access error" in Windows 7. Strangely when he would login with a different username, the application would open fine. I figured there was something with the permissions of the application, it would require elevated rights for the user to open it. I gave this user administrator rights, but the application would still not open.
Finally this is the procedure i followed to implicitly define, that the problem application should always Run as Administrator
1. Right click on the application and click on properties
2. In the Shortcut tab, Click on Advanced.
3. Tick the box "Run as Administrator" and click Ok.

The application should now open fine.
Hope this helps.....

Sality Removal Tool

This post explains about these virus, its variants and types: Virus.Win32.Sality.aa, Virus.Win32.Sality.ae, Virus.Win32.Sality.ag, Virus.Win32.Sality.bh

What Sality does ?
It infects most of the running processes, denies access to any antivirus website, also would render programs unusable if there is no antivirus. It is actually a script that sits somewhere on the Computer, and keeps infecting the running programs. The antivirus ( if installed ) might get hold of the infected program, but not the actual script, which is why as the antivirus disinfects the program, it gets infected again and this process keeps going. Since the antivirus disinfects the programs, no work actually stops ( atleast in my case ), but the infection is still there.

Ways of infection ?
A few probable ways of infection would be inserting an infected removable drive/ usb, opening an infected email/ attachment and accessing an infected website.

Removal 
Yes, this is the reason your on this page actually :) So lets get to it !!
It would be best to write in chronology what i did.
First i tried updating and running my installed antivirus ( ESET ), it would disinfect the virus affected programs, but not the script, because of which thankfully everything was always working ( infection was on the server ). Then i ran a sality removal i downloaded from a website, that didnt solve the problem.
It mentions a lot of steps about updating and all, since i had already invested 3 hours solving the problem, i directly ran the salitykiller.exe. First it ended all the infected running proceses like logmein, dyndns and others. Then it started to find the script, within half an hour it had found and deleted or as it says killed sality, most of which was found in tmp. Immediately after it was found, the popup that i was constantly getting on ESET saying disinfection of a particular exe, was now gone. I restarted the server and found that i could go on antivirus websites, then i updated ESET again and ran a deep scan, it would find some more residual infected files and cleaned/quarantined it.

Preventive measures
Turn off the autorun of CDs, Removable drives, specially on servers. Also be careful opening email attachments, infact donot use the server for accessing emails or browsing. Keep your server and antivirus updated.

P.S:
One of the most important thing is to be patient, as virus removal can take a lot of time, eventually you will definately find it, Just keep looking :) Best of Luck

Understanding RAID

In this post i am going to talk about Redundant Array of Independent Disks, popularly known as RAID. Having seen it live, i understand it almost perfectly now. So lets get to it.

RAID 0
There is no redundancy in this type of RAID. The data writing method is called striping. It basically just groups the hard disks. Eg, 2 hard disks of 300 GB are installed. Once RAID 0 is configured, the effective disk size would be 600 GB. If one of the disks fail, the data is gone.

RAID 1
This is redundant, also called mirroring and does exactly that. Everything that is written on 1 disk, exactly the same is written on the other. Eg, 2 hard disks of 300 GB, Effective Disk size would be 300 GB, as 1 is the mirror of other ( cannot be said which is primary and which is secondary, as both are identical ). If one of them fails, the other is still working, the faulty disk can be removed and a new can be installed. We can also have a hot spare in this. Hot spare is a hard disk, installed as a backup, it is automatically made active when one of the disks fail. Minimum and maximum hard disks in this is 2 of same capacity each.

RAID 0 1
This is basically RAID 0 and RAID 1 put together. The hard disks have to be even in number. Consider this Eg, 4 hard disks of 300 GB each, configuring RAID 0 1, the effective Disk size would be 600 GB. Heres how. the 1st two hard disks would work in RAID 0, i.e 300 + 300 = 600. The 3rd and 4th would also work in RAID 0 i.e. 300 + 300 = 600. Now both these RAID 0 are mirror of each other i.e. RAID 1, giving 600 GB disk size eventually. Minimum hard disk in this is 4 of same capacity each.

RAID 5
This type of RAID is redundant. It does striping, but has a separate dedicated disk maintaining something called as a parity bit, which helps in rebuilding the data, if a hard disk fails. Eg, there are 3 hards of 300 GB each, RAID 5 is configured, the effective disk size would be 600 GB, because the 3rd hard disk is dedicated for parity check. Now if one of the 2 disks fails, another ( new one of 300 GB ) can be installed or the hot spare would be used and the data would be rebuild with the help of the 3rd disk maintaining parity. It is the most popular type of RAID. Minimum hard disk in this is 3 of same capacity each.

RAID 6
It is due to RAID 6 that i have written this post, i had not heard of it before, started searching for it, saw it live and then thought of sharing with you all :)
RAID 6 is basically RAID 5 with an extra backup disk. RAID 5 can survive if one hard disk fails, but what if even before a new hard disk is rebuild, a second hard disk fails, the data would be gone. This is exactly the reason for using RAID 6, it increases the backup hard disk to 2, so if 2 hard disks fail together, data can still be rebuilt. Eg. 4 hard disks of 300 GB each, the effective hard disk size would be 600 GB, with one hard disk for parity and one for backup. Minimum number of hard disk in this 4 of same capacity each.

Hope the concept is clear, please comment if an doubts. Also, do try it if you can, its fun :)

Lenovo T61 No Audio

Yesterday at a customer site, i was told that a lenovo T61's audio had stopped working. On inquiring when was the last time audio was working and if any changes were made that caused this, the concerned person told me he had pressed the mute button, and since then the audio was gone.
Solution ( one of the most simplest and strange )
Lenovo T61 has 3 audio buttons. 1. Mute, 2. Volume Up, 3. Volume Down.
Turns out the Mute button just does precisely that, only mute the audio. To unmute, use the Volume Up or Down key :)

Excel 2003 files open slow on Network share

Recently one of the users was having this issue on his XP Professional machine with Office 2003 installed. When he tried accessing excel files on the network, they would take quiet a lot of time to open. This is the way i diagnosed/solved it.
1. The excel files on local pc would open fine, which suggested that the installation was fine, but still did a repair which did not solve the issue.
2. After some searching. i reached an article and the solution over there worked. Heres the explaination.

The reason why it opens slow is because of an Add-in called OFV ( office file validation ). What it does is that, before opening the file, OFV reads it to make sure its trustworthy. Now, when this is done over the network, the process takes time, and hence it takes longer to open the file. Disabling OFV solves the problem. Steps to do it.
1. Start-> Run-> Regedit.
2. HKEY_CURRENT_USER\Software\Microsoft\Office\11.0
3. After you select the key point to New on the Edit menu, and then click Key.
4. Type Excel, and then press ENTER.
5. Select Excel, point to New on the Edit menu, and then click Key.
6. Type Security, and then press ENTER. ( You might already be having the key security, if so skip the steps 3-6 and proceed to step 7 to create the key in Security )
7. Select Security, point to New on the Edit menu, and then click Key.
8. Type FileValidation, and then press ENTER.
9. Select FileValidation, point to New on the Edit menu, and then click DWORD Value.
10. Type EnableOnLoad, and then press ENTER.
Note: The default value is 0 which disables the validation.
11. On the File menu, click Exit to quit Registry Editor.

Now try accessing a network Excel file, which should open normally ( faster than before ).

compile error in hidden module: autoexecnew in word/excel

The error "compile error in hidden module: autoexecnew" shows up when word/excel is opened and the error "compile error in hidden module: distmon" shows up when its closed. This is because "pdfmaker.dot" and "pdfmaker.xla" are in the microsoft office startup and microsoft excel startup folder respectively. To remove this follow the steps:
Delete pdfmaker.dot ( for word )
1. Search the file and delete.
2. Locate the file in C:\Program Files\Microsoft Office\Office11\Startup
3. C:\Documents and Settings\User Name\Application Data\Microsoft\word\Startup


Delete pdfmaker.xla ( for excel )
1. Search the file and delete.
2. Locate the file in C:\Program Files\Microsoft Office\Office11\Xlstart
3. C:\Documents and Settings\User Name\Application Data\Microsoft\Excel\Xlstart


These files can be either in both or at one location. Once they are deleted, the error will no longer show up.

Blank screen after "Press any key to boot from CD"

Recently while trying to install Windows Xp professional on an old computer, i got into this strange problem, where nothing happened after i tried booting from the CD. I mean, the computer would be ON, but it would not run the normal blue screen where it inspects the hardware before installation starts.
So, after going through a few forums, i got to know that if the Hard disk had previously installed Linux on it, this could happen.
The solution to this is to Wipe clean the hard Disk. There is a utility "Darik's Boot and Nuke" which does the job perfectly. The link is http://www.dban.org/
Download the iso image, burn it on a CD, boot from the CD and clean the Hard Disk.
Definitely solved the problem for me.

Printer status offline

Suddenly for whatever reason if your printer status shows offline. The very first step is to right click it and click on "Use Printer Online". If that doesn't work, i would suggest to quit trying to troubleshoot it and just reinstall the printer drivers. Thats faster, easier and mostly works fine.

The file or directory is corrupted and unreadable

This one just in. Received an External Hard disk. Once detected and after we try to access ( double click ) the hard disk, it gives the following error "The file or directory is corrupted and unreadable". As the error suggests, it is due to corrupted hard disk. Now to fix this, follow these steps.
Start -> command prompt-> type chkdsk /f L: ( "chkdsk" is Check Disk, "/f" represents fixing errors, "L" is the drive letter). This should run a 3 stage error repairing and finally the drive should open.

Easy Fix :)

Blue Screen of Death Windrvnt.sys

In Most cases, this is an issue with the software FOLDER LOCK.
I have been using Folder Lock for almost a year now. Suddenly yesterday night for some unknown reason ( mostly conflicting software or drivers ) after i logged in to my Laptop, i got this feared and dreaded BSOD ( Blue screen of Death ), with the file name "Windrvnt.sys". This file belongs to Folder Lock. Heres the solution.
1. Boot in Safe mode ( Press F8 at startup and select Safe Mode ) and uninstall this software ( As a precaution,  Before uninstall i would recommend that you login to the software and unlock the locked files). It will ask you for a password you must have specified during installation. Enter that, and uninstall the software. And donot worry as the files that were locked will be released and visible in the folder, and wont be lost or deleted. If you have forgotten the password, try uninstalling from "Add/Remove Programs"
2. If you donot want to uninstall the program for whatever reason, just rename the file "windrvnt.sys" to "windrvnt.old or windrvntsys.old". This will stop the BSOD, but whenever Folder Lock is accessed the Blue Screen will appear.

If anyone has more insight on this, Do comment !!!

There was an error opening this document. The file is damaged and couldnot be repaired.

Ok, firstly to all those who have reached this link frustrated and fuming hoping for a solution, sorry to disappoint, but i dont have a pin point, sure shot solution. But Wait, i can still help you all solve this, the way i did. Let me explain what the problem was
The user had scanned a few files in pdf, but whenever he send it through Outlook ( not sure about the version, but may be 2003 ), the receiver would get the error mentioned in title. This also happened whenever the user received a pdf through outlook. Heres what i tried

1. Uninstalled Adobe pdf and installed the latest version - didnt work.
2. Installed a different pdf viewer ( foxit and digisigner ) - didnt work.
3. Send the same pdf file through google mail - opened fine.
4. Changed the Mail format from HTML to plain text/ Rich Text - Didnt work.

I would also recommend updating the Microsoft Office version to the latest.
For me, the problem somehow solved itself, although a few scan files still showed corrupted when sent. The problem was confirmed as solved, after i scanned a document and send to another user who was able to open it normally. Also the problem of corrupted pdf when receiving was also solved. It is also possible that only certain files scanned at a particular time got corrupted which made the user think it was a larger issue.

Hope this helps !!!

Epson Lq 680 prints junk

One of our clients has the epson Lq 680 printer with print server ( making the parallel printer network printer ) attached. The problem is, theres no print command given but the "printer keeps printing junk papers with useless characters."
The printer has some junk in its memory, so we now have to remove or wipe its memory. The solution is

Turn off the power to print server and remove it, remove the cable connecting printer and power supply. Now turn on/off the power switch on wall/extension/spike ( power cable is connected to the power source but not the printer ). Do this 5-6 times for 5 secs each, this should clear the memory. Now connect the printer cable to the printer and turn on the power switch ( junk prints should stop ), connect the print server to the printer and power it up. The printer should now be working normally. If the problem persists after connecting the print server, the problem is in print server.

windows was unable to find a certificate to log on to the network - Wireless Error

Sometimes when trying to connect to a Wireless network, the following error occurs,
"windows was unable to find a certificate to log on to the network".
Although i donot exactly know the reason for this error, here are the steps that solved the problem for me.
goto Start --> Programs --> Accessories --> Communications --> Network Connections --> Right-click your Connection and select Properties --> Click on Wireless networks tab --> Double click on the network you want to connect -->click on the Authentication tab --> Disable / uncheck the option "Enable IEEE 802.1x authentication for this network".
Either you should now be connected to the network or you can try to connect to your Wireless network.

Note : Even with the windows certificate error displayed, you might still be connected to wireless and get internet access , but these steps would help to remove the annoying error message.

Installing Device Drivers

Posting after long.
Have been doing a lot of formatting these days, installing Windows Xp. Its frankly a matter of 40-45 mins installing Xp, in normal scenario. But what follows after that is the real head ache "THE Device Drivers"
So today i am going to write about the various ways in which drivers can be found and installed. The first driver i would recommend to find is the Network Driver, because once we have the internet the rest can be found. But be prepared for some exert searching and a lot of patience.
To identify the devices the following software is more than handy "Unknown Device Identifier". The url to download this is http://www.zhangduo.com/udi.html
Identify the network card's brand and model, google it and install until the network card is successfully installed. After we get internet connectivity, further devices can be similarly installed using the Software or by going with a more easier approach. This involves installing Driver updating softwares, which automatically finds the drivers for uninstalled devices and updates to obsolete drivers. One can either get them by paying around $ 30 or for free by some rigorous, very very rigorous and painful searching. Some of the good ones are "Radarsync pc updater", "Advanced driver updater", "driver reviver" "Driverscanner" and many more. One advise for people going for the free ones ( find them on www.piratebay.org, www.4shared.com ) is to be very careful when installing them, as these may carry virus, so be extra alert, i have experienced this first hand.
If nothing else works, for devices installed in pci slots, remove them, note down the brand and model and lastly use my best friend GOOGLE.....

Best of Luck !!!

Exchange 2007 and outlook 2007 through VPN

While setting up a new machine in the network, everything work fine, till i used the vpn. When opening outlook through vpn, it started with a password prompt, then giving an error regarding certificate, pressing ok, it would give 2 other certificate prompts, wont call it errors thought. And all worked fine. But the password prompt, and error of certificate, had to be removed. The solution was to remove the outlook profile, manually configure the users outlook profile without auto discovery. This solved the problem.
