authenticating to member server from non-domain client

[Guest Mike D]

Hi,

 

I recently demoted a Windows 2003 file server from a domain controller to a

domain member server. (I have two other DCs.) Previously, when this file

server was a domain controller, non-domain computers could authenticate to a

shared folder using simply their domain user name and password. Now that

it's been demoted, it will no longer recognize a user unless they add the

domain name as a prefix.

 

Why would this be, and is there any way to change its behavior back to the

way it was? (other than reverting it back to a DC)

 

Thanks,

Mike
