Guest Andy Posted January 31, 2008 Posted January 31, 2008 I am recieving a failure audit message in the security log with event id 537. The reason for the error message is 'an error occurred during logon', and it occurs when I run NTBackup. This is on a DC with a domain admin account. Further down the 'Logon Failure' it mentions 'Authentication Package: NTLM' and it notes the DC I am on as the workstation name. One irregularity is that the FQDN is over 15 characters and therefore when it mentions workstation name it is missing the last few letters. I have also noticed that I can ping the two names and recieve a reply. Anyone with any ideas how I get round this as the error message is preventing me from backing up the system state.
