I just joined one of our windows 2003 servers to our AD domain. It has been operating as a standalone server for a while. After joining the domain, when I go to assign permission to anything the only "location" available to choose in the dialog is the local computer. I can select the Locations button to list available locations - but the only one to choose from is the local computer. Any idea how to get the AD domain to appear so I can assign permission to domain users/groups?
You did log into the domain after you joined the server .. right? When you join a computer to a domain, you need to select the domain on the logon box as it defaults to the local machine. That's got me a few times.
Other than that, I'd check your network connection, and failing that I'd get the server to leave the domain and re-join it again.
