[SOLVED] Unable to see other workgroup members

[mork]

I am a very experienced user, and encountered a preplexing problem:

• My computer can see only itself in the workgroup
• It also cannot see the network print server

This is a thinkpad T42, WinXP SP2 and up to date on all windows patches. Trend Micro antivirus - no firewall.

The strange part is that all the following are true (confirmed many times - after rebooting, checking etc)

• three other computers on same lan can see me and the print server
• I can ping the other computers and print server
• I can telnet or HTTP to the print server
• I can enter the other computer \\name\ and get explorer to open a folder to them
• The drives assigned to the other server shares are still functioning just fine
• netbios is enabled everywhere
• the netbios service is started automatically
• DNS and DHCP as well as LMHosts are configured and available
• If I install the netware IPX protocols on other servers, I can also see them on the explorer
• all other tcp/ip functions work just fine
• windows firewall is off
• there is no TCP filtering - all ports are enabled
• I am not running Norton - did that long ago and got rid of it
• I rebooted all the machines on the network and still see this problem

Just prior to this anomaly, my communication drivers disappeared and I had to reinstall the IBM/Lenovo Access Connections which provides drivers and additional configuration tools for the network. I have not yet uninstalled it, and am hoping to see if anyone has any suggestions

You can ping by name everywhere?

Have you tried safe mode with networking to see if it's something that's being loaded in normal mode?

No offense, but I'd like to look at the following results myself.

Hold the Windows key and press R, then type CMD to open a command prompt:

Type the following two commands:

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Actually the problem was resolved more simply.
I noticed two extra filters in my configuration of the LAN connection
TVT and AGN packet filters.

TVT - think pad vantage technologies
AGN - AT&T Global Network

Both are some kind of "uncontrolled" firewall type filter provided as part of communication packages that I use occasionally.

I uninstalled them and voila' - every thing works smooth as silk.

God - what a pain. Since they are not controlled, it is not possible to monitor or disable their features. I still don't understand why only certain operations were disabled - probably just a side effect of partial packet filtering.

That's the kind of data we were looking for.
