NETLOGON error

I recently renamed a BDC “LN03” to “LN01” which was the name of the PDC. When renaming the PDC offline to “LNS01” I got a warning about losing logon info. I proceeded as I had already renamed the BDC. After this logon info like Domain and Privilage was not available to the Logon script. However, users appeared to logon properly except for the drive mappings being incorrect. I then restored the WINNT directory and registry to the PDC (now “LNS01”). Everything appears normal except. 1. Users get an Error 2455 at logon but the rest of the logon proceeds fine. 2. The BDC also gets a NETLOGON error with “Access Denied”. Again the rest of the logon appears normal. How do I get reed of these error messages?
