Remove domain name in “Log on to field”

Hi all,

We have a Win2k Server SP 4 Domain Controller. We setup a child domain and tried to synchronize the data between the two domains. This was only a test and we removed the child domain from our network. When the users log in from a workstation, on the domain “Log on to field” it is still showing the test domain names. How can I remove these test domin from appearing on the workstations domain selection field.

Thanks and regards,

Minhaj.
