win 98 machine not loging on to windows 200 domain

i have a win 2000 server domain.

there are roughly about 600 desktops which have either
XP, 2000 proffessional or win 98 as OS

i have a DHCP network.

recently the win 98 machines have not been logging on to
the domain if i configure them to get the ip assigned by
the DHCP server.

There is no problem in the IP getting assigned but the
machine does not log on to the domain

i get an error saying that there is no domain server
available.

if i give an fixed ip to the same machine, i am able to
successfully logon to the domain

i tried installing the DS client also but there is no
change?

what could be the problem ??

Dheevar,
What kind of DHCP server are you using?

Is the DHCP server providing all the correct required
information, IP Address, Subnet Mask, Default Gateway,
WINS and/or DNS servers?

Does this machine have more than One NIC installed?
