Probably a Microsoft Support ticket, but thought I'd try EE first.
On a Windows Server 2008 with SQL 2005 which is a member of a SBS2008 domain, within the past days, several services fail to start with Access Denied. Webroot is the security and shows no compromise.
The services that fail are ADFS 2.0 and all Microsoft Dynamics CRM services. SQL services start and are running with the exception of SQL Server VSS Writer which fails as a Local System account. SQL Management Studio is working. There is a mix of user accounts for the MSCRM services and ADFS is Network Service.
A couple recent changes might be possible clues, but there is no evidence to support them being the cause. I changed a domain admin password a couple weeks ago. I did MSCRM solution updates a couple days ago. My first attempt to repair this was to restore a SQL database backup of the MSCRM data prior to the solution updates. That did not solve the problem, the services still fail to start. I changed one of the CRM services from its user account to Local System but that did not make any difference, still fails with Access Denied.
Application Event viewer shows only IIS-W3SVC-WP errors with several ID's 2214, 2268. System Event viewer shows ID 7000, Access Denied for the associated services that fail. ADFS Events show ID 364 from 5-7-2015 8:48am through the present time. Administrative Events show MSCRMMonitoring errors ID 18690 starting 5-6-2015 6:16 pm.
Reboots do not help, system is fully up to date. I'll try a DSKCHK as well.
There does not seem to be a problem with domain membership, I can login, even remotely, without trouble. The problem seems to have happened overnight, and a day after the solution updates were done. But MSCRM was working after the updates.
Thank you for any help.
