Hello! Having problems making a standard Windows 2000 Server machine connect to a Cisco 3000 VPN Concentrator.
Cisco doesn't state whether Win2k Server will run the client but according to their TAC guys it should.

Client = Windows 2K Server, VPN 4.0.3(f), Natted behind Cisco 515
Concentrator = Cisco VPN 3000
Last part of the log from the client is below (IP's removed for security)

Received ISAKMP packet: peer = XX.XX.XX.XX

Received a DELETE payload for IKE SA with Cookies:
I_Cookie=C37052AFD5B60D72 R_Cookie=F82BD4D339C2CDE9

Then it disconnects - any ideas? Unfortunatley i've not had much experience with the VPN 3000 so i'm stuck!

Thanks
 
Did you try enabeling NAT-Transparency? (Under tunnelling protocols/ipsec on the concentrator)
