Windows 98 Logging into a Windows 2003 Domain

I have 3 Windows 98 workstations that are in one of our
branches offices and will not login into the domain. I
had setup these computers in the headoffice and sent them
to calgary. They had no problem logging into the domain
in Edmonton but in Calgary the receive this message:

"No Windows domain controller is available for
domain 'domain name'. The following error occurred:There
are currently no logon servers available to service the
logon request."

I am not sure why this is happening and there is also a
problem when I map a drive to the server (not logging
into the domain) it will disconnect after a certain
amount of time and than I will need to reboot and remap.

It's a real pain. Does nayone have any ideas?

Thanks in Advance!
