Ran DCPROMO on servicedesk server and cant set permissions to domain

I have been cleaning up my domain and one of things was building a new DC with 2K8.  I did this and wanted to get rid of one of the 2003 DC's which was one who happened to be doing all sorts of SQL stuff and held the servicedesk.  After running DCPROMO, all the access was stripped from the database and the windows internal database would not start and no domain account could access servicedesk.  I set the windows internal database to local logon and it started but no domain accts could access it.  I can logon as administrator but the issue is it has no rights to do anything.  Can I get into the SQL database and set those rights at all?  All my information for the company is in the servicedesk still.
 
Any ideas appreciated
