Login does not exist - Error 15401

Hello,
Our IT Infrastructure group had recently renamed the Windows login username
from Bob_J to JBob. When I tried to add the new login with the new username
after the change, I received the error '15401: Windows NT user or group 'Cor
porate\JBob' not found. Che
ck the name again.' I used the sp_revokelogin to drop that login but it stil
l did not allow me to add the new username. I know the issue related to SID
but I had removed the login according KB324321.
If I added the login 'Corporate\Bob_J' back, it was fine. Under User Manager
, user Bob_J no longer exists. Have anyone had experience with this? If so,
how can I correct it? Do I not have a choice by either using the old usernam
e or create a new Windows l
ogin user? Any help will be greatly appreciated. Thank you.This could be ralated to the following article:
http://support.microsoft.com/?kbid=329420.
SQL Server uses the function mentioned in the article. If you have SP4 of
Windows 2000 installed this may not be the problem. The quick resolution is
to reboot all serves involved starting with the SQL Server to see if that
will resolve the problem and then the domain controller.
