Access Denied In windows 2008 Server R2

Question

Hi team,
I ma trying to implemet a Lab setup to impelment 2008 AD/DNS/DHCP and work on SCCM 2007 deployment concepts. We have two 2008 R2 server adn one Win 7 mahcine all in Workgroup environment.
I tried to Promote one of the Server to DC. As the initial steps, i loaded the AD DS binary files in the mahcine and renmed the machine name to something accrording to DC standards. I did all this logged in with the defauld Administrator acct.
We rebooted the machine and i cant login with the dafualt Administrator acct anymore. I am gettin Access Denied.
I connected to the computer mgmt snapin remotely created a new user, added to administrators group,Remote desktop users group and can login with the newly created account. but not the Deafult Administrator acct. Have anyone come across similar issues. Please
letme know what could be the issue, since i have never faced this issue before :-( :-(

Hiya,
It sounds like the following:
1: When you started working with your server you were using your local Administrator account, doing everything on the server.
2: When you promoted it to a DC, it no longer has a local Administrator account, but only a Domain Administrator account. You need to login using <Domain>\Administrator and not <ServerName>\Administrator. When you try to logon, it will have the
previously used local administrator account as the account.
3: When you remote connected you just wrote Administrator, which resolved to the domain administrator account, hence you were able to login and create the new account.
That would be my guess :)
