Authentication failure - can't find domain accounts

We're getting an error where we can't add a login with the full dns name of a user - domain.xyz\user, for example. Get an error 15401, "Windows NT user or group domain.xyz\user' not found". The domain has a different Netbios name and DNS domain names, so we can add the user when we use the form "netbiosname\user". So far so good.

Unfortunately, we have another application - Office Share Point Server whose shared services provider won't run, giving errors in the event log every 60 seconds that "Windows NT user or group 'domain.xyz\user' not found".

It looks as if SQL insists upon listing users in the form netbiosdomainname\user, and applications that look for domain.xyz\user simply fail to authenticate.

Suggestions?

SQL Server only understands NetBIOS names for Windows principals (i.e. when creating a login), but authentication via SSPI should work normally.

Please let us know if you still require help on this issue, if so, we will need more details regarding the failure, if possible the SQL Server error number/message.

Thanks a lot,
