subnet mask keeps changing to 255.0.0.0 from 255.255.0.0 1

[Scruby]

I have a user on a Windows 98 box her subnet mask keeps changing to 255.0.0.0 from 255.255.0.0, I always have to run winipcfg command and release and then renew to get the subnet mask back. I have updated her computer, reinstalled TCP/IP. Has anyone seen this before? P.S. When she tries to logon intermittently she will receive this error message that’s how I know the subnet mask has changed.

ERROR: the domain password you supplied is not correct, or access to your logon server has been denied.

Thanks in advance, Scruby

Some Win9x obtain different subnet mask

Symptoms: In your domain network, some computers (most are win9x) obtain mask 255.255.255.0 instead of 255.0.0.0 randomly and they can't logon to the Domain. IPCONFIG /renew doesn't fix the problem. If you assign static ip and correct mask, the computer will be able to logon without any problem. If you check the WINS, you may find many bad records.

Possible reasons: you may have another network device (possible a router) except main DHCP functions as a DHCP
