In this case something very bad has happened and you are best off throwing away the UPA service application and starting over.Hacking out a solution is not a good idea, and will almost certainly cause you further problems in the future.No really, I can’t count the number of times steps have been missed or I get a response like “oh, I didn’t think I needed to do that”.If you follow the procedure you will be successful unless you are hitting an environmental or other known issue.Amazingly, this article has already been viewed over 260,000 times! Of course the Microsoft documentation in this area is weak at present, and UPS is what you could call a “rough edge” of Share Point 2010. Furthermore the amount of time I spend helping others with UPS related problems as a result has inspired this follow up article which will cover the most common issues people experience.Before I dive in, I must stress that the number one reason people have problems is that they do not follow the procedure!
When we hit Start in Services in Server a series of tasks are run, which are akin to running the second stage of the Forefront Identity Manager setup.
After around 20 to 45 minutes the status will return to Stopped, and you can attempt to start it again.
In some cases, the status will remain as “Starting” even after reboots.
You can however, manually kick things back to the state before the starting of the UPS service instance. the account that the two FIM services run as (which is the Farm Account).
This can be necessary in some cases, but again, I strongly recommend you start clean by deleting and recreating the UPA. Incorrect Permissions are the number one cause of the infamous “Stuck on Starting” behaviour. If you don’t set the permissions correctly things won’t work, its that simple. And the Synchronization Connection account, this is the account which actually performs the sync. So there you have it, a summary of the rights required. Well before you start, ask for proof in the form of a screenshot that they are set correctly.
This is a tremendous growth opportunity for a candidate who possesses a mix of technically strong modeling skills and advanced interpersonal skills.
