We have 5 computers on our home network. But on one computer, it suddenly has stoped working. When you open "my network places" you used to be able to see all the computers on the network but now it no longer shows any of them. We also have a network hard drive that no longer shows up.

All other computers work fine except they cannot access this one problem computer? If I try to connect to MSHOME it shows this problem computer but it wont allow you to open it. -Its like there is some kind of block.

This problem seems to have happend after I pulled a CAT-5 wire out of the router and re-conected it. Which shouldnt have caused any problems but maybe it did.

Additonal info; Our computers are networked like this: Cable modem: to Netgear wireless router: to Linksys workgroup switch: to 5 computers.

Have you checked your firewall settings. I know they shouldn't have changed, but stranger things have happened.

That could be it. I will try altering the settings to Norton Firewall..
