CRM 2011–MSCRMKeyGenerator– Key not being regenerated correctly

Recently in a dev environment, when I tried to bring up our CRM environment, I was getting the following error:

Not very helpful. But if I look at the URL:

http://xxxxx/orgname/_common/error/errorhandler.aspx?BackUri=&ErrorCode=0x8004A106&Parm0=CrmKey%28Id%3aaa{GUID}%2c%20ScaleGroupId%3a00000000-0000-0000-0000-000000000000%2c%20KeyType%3aCrmWRPCTokenKey%2c%20Expired%3aTrue……

So there is certainly something weird going on here.

Looking at the application logs in the event viewer I found the following error:

Current key (KeyType : CrmWRPCTokenKey) is expired.  This can indicate that a key is not being regenerated correctly.  Current Key : CrmKey(Id:GUID, ScaleGroupId:00000000-0000-0000-0000-000000000000, KeyType:CrmWRPCTokenKey, Expired:True, ValidOn:11/03/2013 17:47:19, ExpiresOn:12/06/2013 17:47:19, CreatedOn:11/03/2013 17:47:19, CreatedBy:NT AUTHORITY\NETWORK SERVICE.

After some googling, I found that the reason for this was that the “Microsoft Dynamics CRM Asynchronous Processing Service” may not be running. Which indeed was true in my case. But, after restarting the service, it still was not working.

The final thing that I had to do was issue an iisreset against the server hosting CRM.
