Hi, We are continuing to analyze a very strange problem. Here's what's happening: Users are mapping a network drive on logon, connecting to a RH 7.2 machine with SMB 2.2.1a running. The mapping fails about 50% of the time, sometimes working just fine other times not. The password authentication is being passed to the PDC which is a Win2K server. For some reason when Samba sends the passwords it sometimes sends the correct passwords sometimes not. A successful login occurs with the "domain/id" with the password coming from the login variable that is set on successful login. An unsuccessful login occurs with the "login/domain/id" so it is appending the "login". We are using WindowsScripting host to map the drive. Net use works every time.
