Changing SQL Server service account My team foundation server is running its databases locally and the person who originally installed the system decided to just use LocalSystem as the service account for SQL Server instead of actually planning the accounts out. 

I am trying to create a backup plan (via the TFS power tools Backup Plan extension in the TFS admin console) and it is requiring a domain account in order to complete the plan.

My plan is to quiesce tfs, go into SQL Server Configuration Manager, change the service accounts to a plain 'no rights other than domain user' account, start the mssql services and thne unquiesce tfs.

Are there any problems or concerns I should be aware of before doing this? Will simply changing the LocalSystem account to a domain account cause any problems?
So I finally got the outage to do this yesterday evening and to summarize:


I opened an admin prompt, changed to the 'C:\Program Files\Microsoft
Team Foundation Server 2010\Tools' directory on the application tier
and quiesced TFS (TfsServiceControl.exe quiesce)
Changed all of the databases from LocalSystem to my service (domain)
accounts from inside sql server configuration manager.
Rebooted (I had windows update nagging me for a reboot)
Ensured all of the sql services started
Unquiesced TFS (TfsServiceControl.exe unquiesce)


The only problem I had is somehow inheritance on the Users folder where profiles are stored had some issue that prevented my service account from working. Once I fixed that everything worked just fine. I'm not sure if the profile issue was related to the account change.
