I changed the name of a user account used for a program I developed from RTSQLCMD to RTScheduler. In the ADUC (dsa.msc), I changed the "User Logon Name," the "Display Name," and I right clicked on the account and changed the name using the "Rename" option. At this point, I assumed all was well. Then I hopped into SQL Server and attempted to add <DomainName>\RTScheduler as a SQL Login. I was told the account doesn't exist. So I tried RTSQLCMD, and the account was located. I don't get it. I went to all that effort to change the account name and the old name was still buried in the AD. Can someone explain to me what's going on and what my options are? Is deleting the original account and starting from scratch my only good option?
