Hi Joe! Thank you so much for the quick reply. After re-reading my post, I realize I didn't make it very clear

.
I have my current DNN site running as norm on a W2K3 server with IIS and SQL Express. Everything works fine. Now, I want to move the database portion to a second server running W2K3 and SQL Express. I configured the new SQL EXP server with the same users, etc, and to allow remote connections and can connect to it remotely using SQL Server Management Studio Express. I then created a backup of the DNN DB from the local server, configured users and the database on the new remote server, then restored the DB to the new server. All of this works fine. Then I edited web.config to point to the new server by changing "DataSource=DBSRV\SQLEXPRESS". I then point to the URL and it blows up, giving a generic Runtime Error message.
So, what have I done wrong? I shouldn't have to do anything with the URL or IP address, should I, since the flows still use port 80 to access the IIS server.
