1 PC cannot see our server.

Okay, strange problem here. We have been using a network for about 5 years on this system, with no real problems.

Setup as follows

1x Server, Windows XP Professional with shared drives for data and apps.
5x client PCs with Windows XP Pro, a Z Drive logging into the server.

All PCs are on the same IP range (192.168.0.x) and have Norton Anti-Virus, and have recently been updated to SP2 (though we have turned the firewall of temporarily)

1 of the client PCs cannot access the network. It CAN access the internet via the same network port, so I cannot see a problem with the hardware. This 1 PC cannot see the server (or any other workgroup PCs). All other PCs are working as normal. As far as I know, nothing has changed on the PC since yesterday when it was working perfectly.

I've tried a few obvious things, like manually setting IP addresses (DNS servers too), doing a system restore back to Friday, checked workgroup name etc., but to no avail.

Muchos appreciatus early resolution!

If you need any more info, please ask. Unfortunately I cannot get to site, but I am in phone contact with them.

Are there any errors shown in that client's PC event log?

1. Right-Click the appropriate network connection and goto properties
2. Goto to the propteries for TCP/IP
3. Click the Advanced Button
4. On the WINS tab, make sure "NetBIOS over TCP/IP" is enabled

Would this be on the client PC, server or both?

Have enabled "NetBIOS over TCP/IP" on both server and client PC, but this doesn't seem to have helped... Next suggestion...?

It would be on client PC.
To check EventLog: right clock on "my computer", select "manage".Then go to "system tools", "event viewer". You should check System and Application logs.

No problems seen in the log files to do with the server connection...

I can ping the server from the client PC okay...

On the computer that is not runnning, try the following:

1. Type IPCONFIG /ALL at a command prompt and note the "Node Type".  What is it?
2. Type "arp -a" at a command prompt and note if there are any IP addresses it is aware of.
3. Check that the computer name of this particular computer is not longer than 15 characters
4. If you have NetBEUI installaled, try removing it and rebooting
5. Double check that you have turned off the Windows Firewall on the proper network connection.
6. If you are using static addressing, make sure that you are specifying a WINS server.
7. Try typing \\ComputerName into a windows explorer and see if you can attach to a computer this way.

Okay - responses, but still no resolution...

1) IPCONFIG /ALL came back with Node Type: Unknown
2) arp -a came back with known servers of the server (192.168.0.10) and the internet router (192.168.0.1)
3) Computer name is THEBOSS
4) No NetBEUI
5) Firewalls turned off on all (temporarily)
6) Is this what we checked earlier? If not, how can I check this?
7) Just came back with cannot find computer

IPCONFIG /FLUSHDNS didn't help either I'm afraid...

Really foxing me this one GRRRRR!

okay okay...  calm down...  no need for growling  hehe =)

run "ipconfig /all" on the other clients:

Check the Node Type of the other clients who are working properly..  If they are not set to Unknown, but are rather set to Hybrid, then try this:
http://support.microsoft.com/default.aspx?scid=kb;en-us;310570


Check if they have WINS servers listed.  If they do, and the client not working doesn't, then you have to specify them in the advanced portion of the TCP/IP properties.  The same place where "NetBIOS over TCP/IP" section is.

Restart Computer Browser service on the computer that does'n't see the network. Try to ping the "server" with a larger packet than the default, to see what time of response you got. If at 65500 is loger than 20 ms, change the cable or verify the hub/switch port.

ping -l 65500 server

I presume you mean in the Advanced TCP/IP Settings, under WINS addresses... but what SHOULD be in there? Do I use the IP address of the main server?

that's why you should run IPCONFIG on other computer that are working, to see if they are even configured with a "Primary WINS server".

If other computers are using DHCP, then they are being assigned WINS server.  you can find out what they are by running IPCONFIG /ALL on those computer or looking at the DHCP settings on the server.  Then if you have a computer that is being assigned TCP/IP settings staticly, you must staticly assign the WINS servers too.

I am leaning towards this being a NetBIOS name resolution problem.

I understanded well, the "server" is a windows xp machine? There is no wins server, no dns, no dhcp?

None of the others seem to be configured with a Primary WINS server name.

All computers are using DHCP for IP addresses, but have Primary and secondary DNS servers set.

The "data" server is a Windows XP Pro machine, the gateway and DHCP server is a broadband router, which the computer can "see". It can also "see" the server through "pinging", but not through windows networking.

There is no wins server, and the dns is external. The router serve as dhcp server. Have you tried what I wrote before?

@ CHRISSAND "Restart Computer Browser service on the computer that does'n't see the network. Try to ping the "server" with a larger packet than the default, to see what time of response you got. If at 65500 is loger than 20 ms, change the cable or verify the hub/switch port."

Okay, have done the above. PING speed seems okay at 12ms, though the "node type" in IPCONFIG /all has now changed to Hybrid. Network still not accessible though....

Hybrid is when netbios is active. You know a xp can accept only 5 connection at a time, but I don't think this is the problem here. The network browsing seems to be the problem. I'll suggest to use browstat from here:

<http://www.dynawell.com/reskit/micr..00/browstat.zip>
<http://rescomp.stanford.edu/staff/m..ls/browstat.zip>

and run browstat status

Let's see the ipconfig /all answer on one working computer and on the not working one.

You can run browstat on any computer of the network, but especially on the one not working. It will show the browser master and the browser backup, if any. Then, go to browser master and restart TCP/ip netbios helper.

make sure the one that is listed as Hybrid doesn't still have WINS servers configured in the TCP/IP settings.  Even though hybrid will use broadcast name resolution, it will do so as a last resort.
