I have been working a little with the Cisco VPN in Vista, but no error
relating to the original message in this thread.

Here are some issues I have found, but may not really help anyone....


We previously used the statefull firewall included with the software
with XP. This corresponded with our policy at server side, which checked
that the statefull firewall was in place.

The Vista version does not have the statefull firewall, hence failure to
log in due to a "policy mismatch". When I used the Macintosh login
credentials (for the VCF), this did NOT have a statefull firewall policy
and let the client in without a problem. SUCCESS!


I have found problems with "Reason 442: Cannot enable Virtual Adaptor
error" and cannot figure this one out so far... The *latest* VPN from
Cisco suggests a couple of reason why this happens including an XP
upgrade to Vista rather than a clean install, as well as the Vista UAP
causing problems, but I am still getting issues regardless.

I noticed that a clean install of the VPN would get me a connection, but
after a restart it failed. Uninstalling and reinstalling allows me to
access again - until the reboot once more!

I too have problems with the (Cisco) VPN Client, so if anyone can shed
any light.

I've got a VPN up and running and working really well with XP clients.
However, when I try to connect my PC at home that's running Vista
Business I
get an error "789: The L2TP connection attempt failed because the
security
layer encountered a processing error during the initial negotiations
with
the remote computer."

The router at home is a 3Com OfficeConnect 54g wireless which has IPSec
passthrough (NAT-T) enabled.

Has anyone come across this error before and know what's going on?


Cheers,
Tim.
