Problems installing vpn client / Deterministic network enhancer

[Cala90210]

Ive got a problem installing a cisco software VPN client. Installation goes fine, but when starting the vpn client i get the following error "The necessary VPN sub-system is not available... blablabla

After lots of search i found out that the problem is with the DNE-service (witch should be running, but isn't)
Some people say its a part of microsoft services other says its a cisco service that should be running ???

Is it in fact a part of windows XP networking ? How do I install it ? and what does the DNE-service ?

Extra Info :
Deinstalling, Reinstalling, etc... didn't help.
Finally we formatted and reinstalled the complete pc-system in Windows XP SP1 an immidiatly installed the vpn client (to have no conflict with other software)
The windows XP is fully patched and up to date.
The system is an IBM thinkcenter M50 pc, P4 2.6Ghz, 512MbRAM. Cisco VPN client 3.6.6
In the event viewer the following line is inserted when starting the client.
"Cisco systems IPsec driver-service is depended of the not existing DNE-service"

Any hint would be welcome ?

It is not a Windows native service. There have been known compatibility issues with the DNE VPN driver under
Windows XP. The DNE driver in your Cisco client may be outdated. Check whether the Cisco VPN client software has an updated version using a XP-certified DNE driver. DNE refers to the Deterministic Network shim used in 3rd party VPN clients.

Update your Cisco VPN client.
