v3.0 Cisco IPSec client on W2K

[Alastair Morrison]

I have a Cisco 3030 concentrator running v3.0 code configured
with a group (internally configured) enabled for IPSec.

I have an NT4.0 machine running the v2.5 Cisco IPSec client.
A W2K machine running the v3.0 Cisco IPSec client.

The NT machine establishes a connection.

The W2K machine fails with message
- Remote peer is no longer responding.
The corresponding Event log message(s) on the concentrator being
- Duplicate first packet detected.

Both clients are configured the same (such as they can be).
I have tried changing various of the IPSec settings on the concentrator
to no avail.

I would appreciate any views on how to get the v3.0 client on W2K working.
Please reply to my personal address as well as the list as I receive the list
digest and the sooner I get some guidance on this particular issue the better!

Thanks,
