4.2.5 WinRM ZenPack 2.6.7

Had asked this in a similar thread, but figured I'd start my own as it doesn't relate to modelling the device.

When one of my monitiored Windows servers is rebooted, just as it has finished starting up there is an error generated inZenoss.

"HTTP Unauthorized received on initial kerberos request. Check username and password"

This only occurs when the servers are rebooted, and only once. I can continue to model, and monitor the server without problems.

I've run a packet capture as per the ZenPack recommendations, however I'm not capturing/seeing any error
