Edge Client Configuration Data Corrupted

Mike, sounds like we're on the same boat. I've opened a case with F5 support and we've tried various things but have yet to reach a resolution. Let me ask you this, do you guys use redirected profiles for your AD accounts? Can you have an affected user login with their account to another machine that has the F5 client installed and see if they have the issue there?

We use redirected profiles and the issue appears to be user-specific and not machine-specific. I've tested with accounts that don't use redirected profiles and they work just fine on the same machines that other users have issues with. We've tried modifying, replacing, and removing the config file at C:\Users(username)\AppData\Roaming\F5 Networks\VPN\client.f5c with no change.

Interestingly enough, I downloaded the BIGIPEdgeClient.exe from another F5 (we have production and lab ones) and it seemed to resolve the issue for one user, yet another user continued to have issues. F5 support gave me another client to test that came from one of their F5's but it made no difference.
