AD Agent Error E455
This is a probe error code that means "Access denied" -- the probes of that workstation are failing. If the user isn't being authenticated at all, it's likely that they're not logging in to the domain, or their login record isn't being parsed perhaps. But then when we go to probe the workstation, the probe is failing on a permissions error. There are a variety of possible causes, perhaps the machine's firewall is up, or it's not even a member of the domain, or the secure channel is broken to the domain controller, etc.
Some suggestions:
- If WMI probes are in use, run the new WMI configuration script (bin\WMI-Probe-Setup.vbs) on the target workstation.
- Detach the machine from the domain and then rejoin
- Turn off the firewall -- does the problem go away?
