The same problem was asked by someone else last year (https://www.techrepublic.com/forumqa/thread_detail.jhtml?thread_id=48706&src=search) but none of the solutions are appropriate for us.
Here's the problem: We have several hundred workstations, and occasionally some of the Win98SE's end up with the wrong subnet mask. (i.e. instead of 255.255.252.0 they get 255.255.0.0 or 255.0.0.0). We have only noticed it on Win98SE's. We have ruled out switches, NIC's, or workstation hardware as there are no consistent variables. We are using W2K DHCP server, but noticed earlier when we had NT 4 DHCP server.

You have to make sure that dial up networking is disabled in these computers. The problem only occurs when you are searching the network and the dial-up adapter tries to access the network. You could just disable TCP/IP for the Dial-up adapter. This worked for me anyway. Hope this works for you.

easier way..go into device manager and just remove the dialup adapter form all the win98se machines....tcp\ip will go with it(in terms of only going away for the dial-up adapter)..
