0x80070002-A problem is preventing Windows from accurately checking the license for this computer

A problem is preventing Windows from accurately checking the license for this computer.
Error Code: 0x80070002

When Windows XP boots up, after the Welcome Screen a message comes that shows the above message, and it does not allow you to login.
Solution!

Boot into Safemode

Press F8 While booting just after the BIOS screen or during the OS Selection menu.

Then do the following in the command promt.

cd %system root% \ system32
regsvr32 licwmi.dll
regsvr32 regwizc.dll
regsvr32 licdll.dll
regsvr32 jscript.dll
regsvr32 vbscript.dll
regsvr32 msxml.dll
regsvr32 shdocvw.dll
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 dssenh.dll
regsvr32 rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 sccbase.dll
regsvr32 slbcsp.dll
regsvr32 cryptdlg.dll

Reboot and check if the problem persists.

If not check if the following files are present in the System32 Folder

%SystemRoot%\System32\secupd.dat
%SystemRoot%\System32\oembios.dat
%SystemRoot%\System32\oembios.bin

If any of these files are missing, restore these files, from the setup disk, I386 folder or from another system.

To restore from a setup disk, put the CD in, and browse to the I386 folder copy the file with extension XXXXX.XX_ where XXXX.XX is the file name with first 2 letters of the extension. Rename it to a .cab file and extract the file to system32.

Reboot the system and now try again.

Your problem must be solved.

If still your problem persists try the following from Microsoft knowledge base.

4. Quit Registry Editor.
5. Restart the computer.

Reset the drive letter of the system drive

Best of luck...

Official Gmail Blog: 9 reasons to archive

Guess GMail wants all its users to archive their mail often.

We hear reports that many users don't archive their email. If you don't regularly click on the "archive" button or never even thought about it, here are some reasons you might want to get in the habit. Archiving just means moving mail out of your inbox and storing it for safekeeping. Your messages will be waiting for you when you click All Mail or search for them.

9. Phone numbers and addresses
You never know when you'll need a phone number someone emailed you or an address that was in a signature.

8. Procrastination
Sometimes you want to get a message out of your inbox, but you don't want to deal with organization, and you don't want to trash it.

7. Posterity
Just because you’re not famous now doesn’t mean that in forty years (or fifteen minutes) you won’t want to write your memoir.

6. Winning arguments
“But on May 5, 2005 at 8:43pm EDT you said….”

5. Mailing lists
Do you really need to know what Clintobamccain is doing every day? Auto-archive* their messages until you want to donate again.

4. Birthdays
Search for “grandma birthday” and voila, find the message you sent her last April. Aren't you glad you archived instead of deleted?

3. That guy
Remember that guy you thought you’d never need to get in touch with ever again?

2. Because you can
May as well use the free storage space. Plus, clean inbox = clean mind.

1. Fate-tempting is bad. You just never know
Thirty-one days after you send that message to the Trash and it gets permanently deleted, you're going to need it. Don't tempt the fates.

Guess Mails are filling up the harddrives, archiving might zip the contents and store it so that they take less space. Does gmail really have enough HardDrive space to give everyone 6GB+ of free email space ?

What do you think?

microsoftpowerpoint.exe win32 usb worm manual removal

MicrosoftPowerPoint.exe

MicrosoftPowerPoint.exe is a worm that spreads throught the USB Memory Sticks/Pen Drives from computer to computer. It slows down all usb operations.

Manual Removal
Since the virus automatically hides all the files, you cant easily find it.
First run msconfig, and look at the start up values to find the location of the virus.
Remove that entry by unchecking the tick mark.
Reboot the system.
Do the steps given below in the registry to unhide hidden files.

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Explorer searchidden en 1

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Explorer searchsystemdirs en 1

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Explorer\Advanced hidden en 1

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Explorer\Advanced showsuperhiden en 1

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Explorer\Advanced superhiden en 1

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\NOHIDDEN CheckedValue 1

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\NOHIDDEN DefaultValue 1

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL CheckedValue 1

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL DefaultValue 1

Find the location where it resides, from msconfig and delete the contents of the folder. Usually in /Documents and Settings/User/Local Settings/Temp/.

Now the system must be free of the virus.
Disable the autorun
to prevent further infections.

To prevent infections again to the usb, delete the contents of MicrosoftPowerPoint.exe and place a 0byte file with the same name.

Thats all
:)
