[OK]

Do you have a WINS server at each site? Are they replicating their data with each other?

What happens if you try to do "net view \\ipaddress" from a prompt?

Are the clients XP? Have you enabled NetBIOS over TCP on them?

What about the servers? What OS are they?

Are you running active directory?
If you are then you need to make sure every machine is using the DNS on the main domain controller. AD uses DNS for lookups so if you don't have the DNS server configured correctly machines cant find each other.

If you are not running AD or don't have all machines on the domain then set up a WINS server for all nachines to use.

Wins is setup on main site server and DHCP on the Remote PIX hands out both DNS and WINS.  There isn't a server at the remote location.  Machines are part of the AD.  Server is running SBS 2000 SP4.  No Netbios is not running and yes the clients are running XP.

Thanks for the responses...

 

It would be worth enabling NBT (NetBIOS over TCP) as a test. I have seen issues in the past with WindowsXP machines not being able to access resources across a "WAN" link (including VPN) when NBT was not enabled. And, with this protocol, WINS is a necessity. Make sure that the machine functioning as the WINS server lists itself, and -=only=- itself, as the Primary AND Secondary WINS server.

Enabled NBT.  No effect...  All ok with the WINS server...

The part that appears odd is that the communications *appears* one way. In reality, there is two way communications happening because at least some of the traffic is TCP-based. It sounds like there might be something else in the way that is filtering packets.

Check for the following:

Windows Clients running a firewall software program? Or, XP running with the firewall service enabled on the NIC?

A router passing the traffic that may have access-lists to filter traffic.

Try turning the monitor level logging on the PIX up to debug, shell in, and run a "terminal monitor" to see if packets are being discarded for any reason.

You could also try debugging IPSEC.

One other thing of note - I have been told by Cisco engineers that setting up some components of the PIX software through the PDM causes issues as it doesn't complete the configuration. They did tell me that it was VPN-related sections of the configuration, but that's all I know for sure.

Hello all.  We fixed it.  For sh!ts and giggles we swapped out the PIX and applied the config to it and it works.  We are sending the "Broken PIX" back.  As the old addage goes.  "Check Hardware first, then software"  How true is that?  I appreciate all the comments and help.
