I demoted a 2008r2 domain controller. Now I cannot log into SQL server. SQL was installed on this DC because at the time because this was there only server. Made 2 Manage software runs on this server and the database for this software is installed on SQL. I didn't realize that this would break SQL. Anyone know any fix for this? I won't be back to work until Tuesday to address this, but I an trying to research this now. Hopefully I will have a fix for this by Tuesday to get our M2M software backup and running.
