Recently installed SP1 to an XP machine. (I am not completely sure that this was the onset of the problems, but I am trying to narrow it down). The computer is on a LAN with several other 98 computers. The 98 computers talk freely to each other. I can see the other computers from the XP computer, and even get into the list of shares on the computers. But when I try to access one of the shares, the XP computer locks up. It is similar when the 98 computers try to access the XP. I have removed the task manager check from XP registry, and tried the wmiprvse.exe service but no avail. Any help anyone can suggest would be greatly appreciated.
 
LAN is behind Belkin router, DHCP is enabled. All computers are in the same workgroup. XP edition installed is XP Home (gasp). Other computers are a range of 98 and 98se computers.
