Cisco VPN not receiving any packets, can't remote desktop?

[Busie23]

I have a windows 2000 box with the Cisco VPN client trying to connect to the domain so a user can hit their XP Pro desktop.

When the w2k pc is on our network (not added to domain, just plugged in for internet) it can remote desktop just fine. As soon as it connects to the VPN while on our network remote desktop goes out the door? The VPN is hosed I just can't figure out ho to fix the connection. I can do this same test with another box on our network and it will vpn in fine and remote so I know were good there.

The box had a ton of spyware/virusses, but that was all cleaned up with spybot, adaware, ewido, hijackthis, smitrem, SAV 9.0, etc. All clean. I think something may have gotten hosed up from it though connection wise. It also has some Alltel DSL system check software instaled. There is no firewall whatsoever so it's not like a port is getting blatantly blocked etc.

When I check the status of the VPN connection it is sending out data, but not receiving any? Zero data receieved.

I played with the MTU a bit...

Could the spyware hosed up something, or possibly one of the spyware cleaners? maybe one of them decided to block something the VPN needs?

Network card not cooperating? I'm in the process of swapping one out...

I can't ping anything once VPN'd except the box itself and the VPN concentrator, still no packets received though? Weird?

Any ideas?

have you tried using the IP address of the XP box to connect rather than the name? Or using the fully qualified name?

I have a reserved IP at work but at home on VPN I always need to use fully qualified names for some reason that I can't remember

I tried Ip addy, but not fully qualified. I'll give that a whirl right now... I'm still thinking no since I don't see any packets actually being received by the connection.

try the VPN outside your network, i think there are problems if you use it internally

at work we have a separate DSL line by the helpdesk to test VPN and other junk from outside the firewall

Sounds like NAT is involved somewhere and the vpn concentrator/client aren't setup for NAT traversal.

But most of the time LAN access is cut off when using a VPN. No split tunneling allowed.

I reset the TCP/IP stack and I'm getting packets now. Remote Desktop connects but it takes a long time. That will work for now.
I tried it on our DSL line for fun, but still same results. Good idea though. I hadn't thought of doing that all night!

Thanks!

speed will depend on your DSL speed and the company's connection to the internet as well as the client

MY XP box is 1GB RAM and I have enough bandwith to the mothership to run IP KVM's from home
