Well, it wouldn't say unfortunately as a single login wouldn't be the ultimate setup and since the network you describe is more powerful and complicated than what Bill Gates' uses, it would be silly to have a single logon for the domain.
I was under the impression and HOPE now that I am misunderstanding Wendell more than you, because if he is only "configuring it" than that is no big deal.
I must say that when I install AC on my computers which is a simple domain using all XP Pro and one SBS 2003 Standard R2, AC automatically finds SQL Server. All other accounts log in and click on the icon and it finds the server database as well with no setup assistant. The only thing I can say for certain (which I imagine you are set up the same way) is all of my users are domain users with the same permissions for the database. When I say permissions in this sense, I am talking about when each staph member was set up as a user and made part of the domain users or Power Users, etc. It is possible that if the users had different permissions, they too, would be able to access the database without any issues.
I do have to say, though, that I, like you Walter, have had to set up many, many accounts. But, in the end, having to browse to the path doesn't seem like that big of a deal, no offense intended.
In fact, even though my staff comes running to me for many things, they all know that their bonus will be smaller if they are not able to browse to the AC database after being shown a few times.

I will step down now as it appears that Walter is eons above me in the network field, and I welcome him aboard to help all of us with networking issues.
