The specified domain either does not exist
In a small office we had our previous server is Windows Small Business Server 2003(SBS 2003). We are trying to have a migration in our data to new Windows Small Business Server 2008 because some of its new feature is really needed in our database program. Going back, after a full installation, configuring network address, and some configuration of this new server, we launched the DCPROMO in SBS 2003 and got a message box Active Directory Domain Services Installation Wizard. We try to isolate the said trouble in physical network connection but no luck. Please help us with this error encounter. Your good ideas are really appreciated. Thanks in advance!
