I have seen many articles on this subject, but have yet to resolve the issue.
I have IIS on one server and SQL Server 2005 on a second server. Both are stand alone servers and not part of a domain. The SQL Server is sitting behind a firewall with the proper 1433 port being opened. With the firewall set to passing everything and no
restrictions, the same error occurs.
Here is what I have thus far:
I don't know what I'm missing.
If the servers are added to a domain and a domain user is used, everything works fine. However, the security policies I need to work with prohibit public webservers from being part of the domain and this particular database must also be isolated from our
internal LAN and domain.
I've seen many posts on this and I think that I'm doing everything that is said to do.

What does your connection string look like? You may also get better help over at

Here's the connection string I have. It is an instanced SQL Server btw.
"Server=SQLSERVERINSTANCE; Integrated Security=SSPI; Persist Security Info=false; Initial Catalog=DBNAME; Pooling=true; Min Pool Size = 12; Connection Timeout = 30; "

Do you have to use Integrated Security? That always seems to be problematic, especially in non-intranet scenarios.

Yes I am. And yes it seems to be.
What do your recommend?

SQL Server security, and set the username and password in the connection string.

I was hoping to not have to do it that way if possible. But I will encrypt the user name and password.
