You're right that it was to do with certificates! In the end, I had to alter Group Policy slightly to affect the certificates the clients were trusting. I had inadvertently set them to only trust enterprise CAs and not trusted root certificates.
We have the same message on a Windows XP machine running the VPN 5.0.02.0090. We tried updating the certificates using ROOTSUPD.EXE, and by right clicking on vsinit.dll and installing the certificate in the instructions above. However we are still getting the same error message.
We have also run a virus/spyware scan and it didn't find anything. If you can give me anything else to try fixing the problem it would be appreciated!
