Question : Windows Server 2003 immediately logs me out

When I try to login into my Windows Server 2003 I immediately get logged out with the following error:
"Windows Product Activation

A problem is preventing Windows from accurately checking the license for this computer. Error Code: 0x80070002."
I found a patch that may be related, (link below) but I cannot run the patch on the effected server because I can not login to safe mode or regular mode.

Answer : Windows Server 2003 immediately logs me out

If that solution doesn't work, see if you can see if you can start the machine in safe mode and look in the Event Viewer.  Check the System event log and look for an Event titled "Windows File Protection" with Event ID "64005".  The error may display that some files are missing, such as:

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

Try and restore the missing files from another machine or use the command "sfc /scannow" from the Run command to attempt to automate the task.

Scan for viruses/spyware when you are up and running normally, as this is another possible cause.
