Hi All,

I have to move the DotNet Nuke web site and Database to a new server. I belive the DotNet Nuke is 1.x version, very old. Used to run on Win2k and Framework 1.0.375 version.

New Server Config
Windows 2003.
 IIS6.0.
SQL 2000 
All running on the same machine.
Frame works installed.
1.0, 1.1, 2.0.
IIS configured to run ASP.NET 2.0(tried to run under 1.0 too).

Migration Steps:
creaetd virtual directory under default website and pointed to the folder where .sln file is located.
Manually created Database and imported data and schema from the old DB.
Modified the Conn string parameters in the Web.config of dotNet project.

But when I browse to the desktopdefault.aspx page I get the following error. PLease help. This is production isuue.
*************Error********************
Server Error in '/DotNetNuke' Application.
