System.Runtime.InteropServices.COMException: The system cannot contact a domain controller to service the authentication request. Please try again later. (Exception from HRESULT: 0x80090350) ---> Microsoft.Crm.Reporting.DataExtensionShim.Common.ReportExecutionException: The system cannot contact a domain controller to service the authentication request. Please try again later. (Exception from HRESULT: 0x80090350)
Interesting to say the least and something I had never seen before. My inclination was that a domain controller was down or somehow the connection to AD was severed (but then again, how was I able to log on the server). I ran a set command to check the logon sever and was able to ping it fine, along with all of the other DCs. Next stop was at the DNS/Gateway settings on the NIC – compared everything to another SQL/SSRS server that was working fine. Again, nothing seemed out of place.
Off to the handy dandy event viewer! Immediately I noticed a flood of errors indicating that the automatic backups and log shipping were failing. Amidst those errors I found a familiar message:
Whatever was causing the reporting issue was also causing the backups to fail. I made my way through the events until I reached the beginning of the flood and there it was, in all its glory:
Easy enough – the SQLAdmin account running SSRS (and the other SQL services) cannot authenticate because it’s disabled.
Had the customer check AD and sure enough, the account was disabled. Once enabled, reports began working again.
In all, this was a very strange error message for the actual issue. It could have really led us on a wild goose chase into the networking side of things. Probably saved 2-3 hours by reading through the error logs and being thorough in investigation before going back to the customer with the wrong answer. Moral of the story: do your homework.
