I have had issues for about a month now and I am grasping as straws here.. I have about 200 users and about 10 of them every morning have the firewall blocking them from getting to any websites (different users sometimes but mostly the same few running different versions of windows, 7, 8.1, and 10). I go in and check the user status and I find them in the "Unauthenticated users" section and have this error: Agent returned no user name
I can do a test via DC logs and Netapi/WMI and it always comes back fine. After about 2 hours the user will "magically" pop into the firewall via SSO and be able to browse once again.
Now for the things I have done: Updated both agents. Created a new agent on a new server. ( I have 2 agents ) Ran tests to verify DC logs, Netapi, wmi were all working when testing against the IP address of machine. Turned local firewall rules on our domain network OFF via GPO.
Sonicwall support has been ZERO help. We have called them at least 5-6 times. Any help is appreciated.
