Local WS permissions running Windows Server 2003 vs. SBS 03

[Terry]

Using Windows Server 03; Logged on a local workstation as the Domain
Administrator I want to give a domain user administrative rights to the local
machine. I go to users and groups select the administrators group, click add,
and select from the "Entire Directory" sub: "domain.local" select the user I
need to add.

However on a Small Business Server Domain; a local workstation logged in as
the Domain Administrator if I want to give a domain user administrative
rights to the local machine. I go to users and groups select the
administrators group, click add, there is NO “Entire Directory sub:
domain.local” only the local machine name.
Thus I cannot add a domain user to the administrator group on the local
machine.

Is this unique to Small Business Server or is there a problem with the
network. If this is a network error, can I assume it is a DNS or NetBios
error?

It should be as you describe for Server 03 in SBS 03 also. It sounds as if
the computer is not a domain member or some other network problem. Probably
not NetBios, but DNS is a possibility. Did you use the wizards in SBS to set
up the DNS and the client computers? If so, did you then connect the client
computers to the domain using http://ServerName/ConnectComputer?
