MUVPN Established W2K Connection w/ IAS but Drops Connection

[CRadford]

I have MUVPN establishing a tunnel with my W2k network using IAS. It works fine except after a few minutes the tunnel drops the user. Has any one seen this?

I read everything I can find on their web site but nothing matches. Their support is the worst!

What do your FB logs say? Also, what version are you running on your FB? I'm not aware of any FB related issues with this. Any other info you can provide would be helpful.

We are running version 6.2

There is nothing interesting on the log but on the traffic monitor there seems to always be the same sequence.

RECIVED KEEP_ALIVE REQUEST
SENDING KEEPALIVE_ACK MESSAGE
TO “remove ip address” IF_HDR "xxxx" ISA_HASH ISA NOTIFY
DELETING SA: PEER “remote ip address”
MY_COOKIE
PEER_COOKIE
IPSEC_NL_WRITE: FAILED WITH (-1) NO SUCH FILE OR DIRECTORY
COULD NOT UPDATE TUNNEL 0 FOR RGW “xusers” PUBLIC IP 0.0.0.0
DROP HOST “virtual ip address” “xusers” “xuser” SUCCEEDED

I'm running a W2k network in native mode. The current virtual ip addresses are unused addresses on my subnet out of the scope. I tried using a different ip range in case it was a MTU problem but I get the same thing...The docs say you can use addresses from you subnet? Perhaps a keepalive issue? Is there a way to set that? Yesterday I got it to run for about 20 mins before it dropped out so I'm baffled.
