We recently moved from one lan system to another. On the previous lan we used subnet mask 255.0.0.0 and on the current system we use 255.255.0.0. The current system is using win 2k server. Ever since the cutover we have had a problem with some of our win98 PC that for some reason get the old subnet mask (255.0.0.0) in the IP Config and subsequently they can't log in until we do a winipcfg and the subnet mask is correctly change to 255.255.0.0

Be sure that the subnet mask has been chaged on your DHCP server and /you have deleted all existing leases/. You should force a renewal for all your clients after doing this by running a login script or rebooting each workstation.
