We recently switch all of our computers and users to a new domain using ADMT. Since the migration we are having trouble accessing one of our Windows 2000 FTP sites by using a particular username. The error that we receive is the following:
530 User <username> cannot log in.
In reviewing the system logs I get the following error:
The server was unable to logon the Windows NT account <username> due to the following error: Logon failure: uknown user name or bad password. The data is the error code.
If I use domain\username or localhost\username then it works. If I just use the username without the domain distinction then it fails. This was not the case before, however, only the username was required. I have validated that the user has file level permissions as well as FTP operator rights. Also, the user has log on local rights in the local and domain local policies.
I know it might seem simple enough to just use domain\username and get on with my life but unfortunately it isn't that simple. We have several clients that have scripts with the username hardcoded and it would be unrealistic to ask them to change their scripts in this scenario.
