Follow all the steps below to determine why a computer is not showing up in
My Network Places.
1) NetBIOS over TCP/IP must be enabled if you want a computer to show up in
My Network Places. If NetBIOS over TCP/IP is enabled but the computer still
cannot be seen, go to step #2.
2) File & Print Sharing must be enabled
3) No host-based firewall blocking the NetBIOS ports 137, 138 & 139
4) Open a command prompt and run the following command on the problem
machine:
Net config server
If the output of 'Server hidden' displays 'Yes' that's the problem. If
value is 'No" go to step #5.
5) The machine description cannot be more than 48 characters or else the it
will not appear in Network Places.

6) Verify that the TCP/IP NetBIOS Helper service is running
7) On the problem machine, go into Network Connections > LAN Connection >
Properties > General Tab. Deselect the checkbox for File and Printer
Sharing for Microsoft Networks > click OK > Check the box to enable it again
> click OK.
8) Restart the Computer Browser service on the Domain Master Browser (The
PDC of an NT 4 domain or the PDC Emulator of a Windows 2000+ domain).
Although this may not be necessary it can't hurt.
9) A Master Browser (1D name in WINS) may have been recently turned off or
re-started. If no machine on the subnet has been turned off or re-started
recently, go to step #10.
10) This can be caused when a Master Browser, while functioning as such (has
the Computer Browser service running), has the setting IsDomainMaster=FALSE
in it's registry. Go to the Master Browser and examine this setting under
the following path.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Browser\Parameters\IsDomainMaster
