New Computer hidden (WXP-Pro)

[FleetOfFoot]

I've added a 10th computer to our Peer-to-Peer network. All IP settings are identical to other machines and IP address is set by router. New machine is not shown on network yet pinged successfully from other machines. IPCONFIG /All confirms other settings correct.

The new machine can access the network and internet but is invisible to other machines.

New machine was being shown on network until final software adjustments in MSOutlook 2003.

Any ideas? All machines using WinXP Pro.

Another strange thing I've just discovered. If I enter the computer name \\Name into the address bar of Windows Explorer, the computer suddenly appears in the folders bar (but not in the Right Hand window for networked computers)!

Problem resolved itself when I renamed the computer. I tried renaming it back to the original name HOST but it didn't like it. Perhaps HOST is a reserved name that shouldn't be used???
