I am getting an error when logging into a Windows 2003 Enterprise Server that i cannot figure out?The error pops up as soon as you try to log in. It is below"The system cannot log you on due to the following error: The Supplied user buffer is not validfor the requested operation. Please try again or consult your network administrator."There is no error code or anything? Funny thing is, some users can log in just fine but a handful can't? I have google'd this error and have found no resolution?Any ideas?JEff

This Problem is usually from the third party applications. To get the root cause Please do as follows: 1. Click Start -> Run... -> type msconfig and press Enter 2. Click Services tab and select Hide All Microsoft Services and Disable All third party Services. 3. Click Startup tab and Disable All startup items 4. Click OK and choose Restart 5. After reboot, check whether the problem still occursThanks and hope it helps Syed Khairuddin
