I'm having trouble joining a Windows Server SR2 edition to our existing Windows 2003 Standard edition domain. I didn't think there was any difference between the two for Active directory but there appears to be an issue. I had this problem previously when I was testing a new domain controller with SR2 and couldn't join it to the domain. I then rebuilt it with Windows standard edition and it joined without a problem so I'm figuring it's something todo with SR2. I'm getting the following error message
"The version of the Active Directory schema of the source forest is not compatible with the version of Active directory on this computer"
I would expect to get this error when trying to join a 2003 server to a 200 domain.
Has anyone got any Suggestions?
