I have a server running on windows server 2008. Recently we created a domain and added it to the domain. Also it is promoted as an additional domain controller on the network. A domain user account was created with same username and password as my previous local administrator account. Now I unable to login using my local account. I tried loggin in using SERVERNAME\Username, but it is giving incorrect password error message. Is there any way I can retrieve or create a new local administrator account on a domain computer
Login on the machine using a domain admin account. Go into the Computer Management snap-in (compmgmt.msc from the command line). Drill down to System Tools | Local Users and Groups | Users. In there you can create a new local admin account or reset the password for you existing account. If you create a new account, be sure to add them to the Administrators group.
