I have two computers in a DSL wireless network, 1 XP Pro ("New"), 1 XP Home ("Old"). Internet sharing and printer sharing are working fine. File sharing used to work, but yesterday, in the midst of a file transfer from Old to New, I had an inadvertent reboot of Old. New froze up and had to be rebooted. Have lost file sharing on both computers, and repeated reinstalling of network hasn't helped. Get error message when trying to access workgroup, "My Network Places>Entire Network>Microsoft Windows Network>mshome". The designation of the two computers under "Shared Documents" has disappeared. Thanks for any help.
