CRM 2011 – Failed to get priv user group information

I had a bit of fundamental CRM 2011 error today, no one could log on and a Microsoft CRM error report was filling the screen

Error Description:

I think I have had this error before but I couldn’t find much when I did a google search.

Basically when you get an error which effects all users and is a security guid/id error it’s almost always due to the CRM 2011 Async service and for some reason it won’t be running.  There can be lots of reasons for this, things like the servers being restarted and the CRM servers kicks in before the domain controller, password on the CRM async service  expiring.

So I logged onto the server and restarted the CRM 2011 services

there are four or so services and they all start with Microsoft Dynamics, start them up.

I also restarted the CRM website just for good measure
