I've been scratching my head over a weird Windows network problem for a few months. I have six computers in a workgroup-style network and all but one of them is visible in every computer's list of networked computers. The sixth, however, never appears in any list of networked computers, including its own. That is to say, if I do 'net view' on the sixth computer, it sees all five other computers but not itself. I can, however, access the sixth computer's shares by name (e.g. "dir \\six\users" works).

The sixth computer runs Windows 7 x64. The rest of the network is also Win 7 with one XP box and a Win2003 server (providing DCHP, DNS, WINS, mail, and file services). All the Win 7 machines run Comodo firewall. Disabling Comodo on six and refreshing the network list a few times makes no difference.

Any ideas anybody?
 
Which versions of 7 and XP? Are you absolutely sure the non-working box is in the same workgroup?

Can you PING by name and number? Can you post an IPCONFIG /ALL for a working Windows 7 box and the non-working Windows 7 box?
 
I can ping box six from any other computer by name and IP. I can RDP into it. I can access all its shares by name. I just can't see it any network browse lists except for the Win2003 server's WINS, DHCP and DNS admin consoles.

Here's the ipconfig /all for box six:

Windows Broswer Service running?
Click to expand...

To make a long story short, it turns out the browser service requires the ICS service to not be disabled (it doesn't have to be set to automatic start; manual start is good enough) or the browser service will continually stop and restart, preventing the host computer from being browsable.

I had ICS disabled. Setting it to manual fixed the problem.

Thanks for putting me on the right track.
