Recently I spent about three hours of my life trying to determine why the SharePoint 2010 Central Administration site refused to startup on a client’s install (it had been working fine for months). The site consistently returned a HTTP Error 503. I checked all the usually things that would lead to this specific error (e.g. bad password, locked service account, etc.) but none of that helped.
An error in the event came from the User Profile Service stating the following:
HTTP Error 503. The service is unavailable. in SharePoint 2010 Central Administration
Log Name: Application
Source: Microsoft-Windows-User Profiles Service
Date: 9/28/2011 11:45:04 PM
Event ID: 1500
Task Category: None
Level: Error
Keywords:
User: …
Computer: …
Description:
Windows cannot log you on because your profile cannot be loaded. Check that you are connected to the network, and that your network is functioning correctly.DETAIL - Access is denied.
So, I knew there was some type of access problem but again I had tried all the usually things. But then I tried one more thing…deleting the profile (Control Panel > System > User Profiles) for the farm service account and the admin site was back in business! Somehow the user profile from the farm account had become corrupted.
