Win 98 logging onto win 2003 domain

I have a Win 2003 server with about 8 computers on the
domain about 5 windows XP 2 windows 98 and 1 windows ME.
Today about 11am the server disconnected everyone and I
had to restart the windows XP computers to get them to
reconnect the mapped drives, and now the windows 98/Me
computer do not see the domain and cann't logon.
I have tried to force them using LMHOST and HOST to see
the domain but I continue to get the "No domain server is
available..." error on the 98/ME ones. I have taken one of
the 98 computers to another domain and connected it and it
works, so I'm pretty sure its not the computers them
selves.
Anyone got any ideas on this one?
