I am currently trying to fix a problem with one of our VPN users' computer. We have a Cisco Pix 501 firewall which handles our VPN connections to work, each of the VPN client machines are running Cisco VPN Client 3.6.3. There are no known problems with establishing a connection, I just don't seem to be able to get the client software working properly on a Windows XP Professional machine. The program installs fine, however when it is run the error message I get is:
'The necessary VPN sub-system is not available. You can not connect to the remote VPN server.'
I checked the Services from Administrative tools and the Cisco VPN Server (cvpnd.exe) was not started. When I manually start the service the VPN client connects without a problem. However, this is not practical and I can't work out why the service will not start when the system is booted. I tried uninstalling/reinstalling/installing a more recent version, each leading to the same problem. After checking event viewer the following error occurs during startup:
'Faulting application cvpnd.exe, version 0.0.0.0 faulting module unknown, version 0.0.0.0 fault address 0x0012e74c'
If anyone has fixed this problem before I would be grateful for your help.
Thanks in advance
