Jack,
It makes total sense that it does not work in Safe Mode. Safe Mode
disables networking and only enables minimum services for OS
functionality. I would even suspect that you'd have issues in Safe
Mode with Networking as other dependent services would be offline.
If, however, you are suggesting that a normal reboot does not resolve
the issue but booting into Safe Mode and then a normal boot does then
that is particularly curious. For this I have no explanation. As for
continued troubleshooting, it would be necessary to perform a debug
on the Netvanta and look for clues there and on the client I would
make sure there are no conflicting VPN clients installed, AV isn't
interfering, drivers are up to date and the connection is stable.
Running some debug logs on the client side would also help in
narrowing down the problem.

Hi,
We have a user that has a laptop with Windows 7 Professional on it.
They have the Shrew VPN Client 2.17. The VPN gateway that they are
connecting to is an Adtran Netvanta 3430 firewall. The connection
works sometimes and other times it doesn’t. When it fails, it states
that the tunnel is enabled, but you cannot pass traffic. On the
Netvanta side, it states that IKE is up, but IPSEC is down. The last
time we had issues with it, we tried to connect with a different
windows 7 PC and it connected. Then we booted up in safe mode with
the original PC that failed the first time. It was unable to connect
when it was in safe mode, but when we took it out of safe mode, it
could connect. Any ideas?
Hi Jack,
Based on your description of the symptoms, I'd suggest that the Phase
2/Security Association is failing for that connection. The Adtran logs
may provide a hint as to why it is failing.
The Shrew client can also provide debugging output as Andrew suggested.
The instructions for providing a debug log are here:
