Hi Jeff,

Are you using an account that is also on the local machine (like
Administrator)? If yes, and you leave out the domain, the server might
use the local account instead of the domain account of the same name
in which case you might see a difference in bahavior.

This is a wild guess though. You could test this by a) using an
account that is only in the domain or b) use the local machine name as
the domain (look at netbios name in ipconfig /all on server but it's
almost always the first label of the DNS name). If you no longer see a
difference in behavior then that would suggest the server is using
different accounts that happen to have the same name.

This is why you should ALWAYS supply a domain in your credentials.

If tha'ts not the problem, whats is the server? Is it special in any
way (like a NAS appliance or really old)?
