Need help - Lost network 'names'

Windows peer-to-peer network using workgroup names (not a domain). I have a
laptop working fine for 2 years. Plugged the laptop into another network,
now when I return home I cannot see the workgroup or any computers on it. I
can access the internet, and if I specify IP addresses, I can ping and even
connect to the other machines, but if I use the UNC naming, it can't find
the maching. This happened one before, and I had to re-image the machine to
get it working. The catalyst in both cases was plugging in to another
network.

currently \\192.168.1.100\backup works
.... \\server01\backup does not !

and yes, the names still work from any other client, it's only the laptop
that fails.

I'm assuming that there is some obscure configuration setting that must have
changed when I plugged in to the other network, but I can't find it!!

Help
TIA

Please check on that laptop, the DNS server entry is correct.
Preferred DNS server should be same as on other client machines.

You didn't mention the operating system, but try enable NetBIOS over Tcp/Ip
on the connection. The other network may have appended lmhosts file with
some entries.

HKLM\SYSTEM\CurrentControlSet\Services\Browser\Par ameters

Set all but the pc designated as browse master to;

MaintainServerList = "Auto"
IsDomainMaster = "False"

Browsing wouldn't cause NetBIOS to fail. *However*, if his NIC is set to
obtain its NetBIOS settings from a DHCP server and it was told by DHCP
to disable NetBIOS, it might explain part of the problem.

Thanks for the feedback, but still no luck....

I'm running WinXP-Pro on the laptop.

I checked the registry and it matches other machines that work ...
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Browser\Parameters]
"IsDomainMaster"="FALSE"
"MaintainServerList"="Auto"

There are no specific DNS entries (although I don't know why that would
matter since the failures are only within the local network). NetBIOS is set
to default (use DHCP settings), but I did try to enable it and still had
same problem.

I also used the /flushdns option from the ipconfig tool, and no luck there
either ...
