    Exclamation Lost access to Server 2012 Administrator account after removal of Exchange and Active Directoy

    I was doing a test installation of Exchange Server 2013 on Server 2012 (on one server). I did not have AD installed.

    After removal of exchange and AD the Administrator user account has been removed. It created a Administrator.domain folder in c:/users/ with the username of Administrator. But this is not my \users\Administrator folder. My other 3 accounts were removed as well, but the folders are still there -- same problem.

    The only accounts I can see now are the NEW Administrator.000 account and guest.

    The default Administrator account is not viewable anywhere and the c:\users\administrator folder is intact. I tried to create an account called Administrator, but it created another folder called users\administrator.000

    Also, my SSL certificate for my website got messed up in the process: Now I get this error: www.<domain>.com uses an invalid security certificate. The certificate is not trusted because it is self-signed.

    How to do I link the folder up to a user account or recover my default Administrator account? And any ideas on how to fix the SSL issue? I can access via http no problem.

    When you install a new AD on a server you lose the computer administrator account and gain a domain administrator account. When you remove AD you revert to the local administrator account. What the folder is called is not relevant, it's what role the account has that counts.

    You haven't explained where the SSL certificate is so we can't really advise on what went wrong, but the standard method of replacing a certificate is to import the backup copy you exported. If you didn't do that and only have the original certificate you should create a certificate request on the server, then import the original as a response to that request.

    cheers, Paul

    Thanks for the reply. The issues with Exchange not being uninstalled completely I decided to re-install the server from scratch. This took 4 hours compared to many more I am sure to fix what was there.

    I will be seeking someone who can do some training for the exchange installation.

    Exchange installation is easy, configuring it afterwards is the difficult bit. You need to sit down and write what you want and how - post it here and we'll advise. All things like AD, Exchange, SQL etc need planning long before a finger nears a computer.

    cheers, Paul
