Question : Watchguard DVCP VPN won't connect

I have a Watchguard Firebox III. The remote site has a soho 6. The remote site connects to the main site via DVCP vpn. It worked fine for years up until this morning. Nothing was changed with the configuration of this vpn, however an additional remote site was added to the Firebox III config around the time I started getting the problems. I have rolled back the changes, but several (not all) of the DVCP vpn's will not connect. It seems to be DNS related somehow based on the error messages below.

Code Snippet:

Answer : Watchguard DVCP VPN won't connect

When you rolled back changes did you also revert to backup flash image; the DVCP settings are stored in flash and not in the configuration file.

For the current problem; if you remove the tunnel and again, does this help. Are you using VPN manager.

Also, did you upgrade the software/firmware on any of the devices having problem.

Please provide details.

Thank you.
