Hi

I copied my .NET Application from a W2K SP4, SQL2000 to a W2K3, SQL2000 Server.
When i try to run the application, i get the following error:
-------------------------------------------------------------------------
Server Error in '/ApplicationName' Application.
Specified cast is not valid
Description: An unhandled exception occured during of the
current web request. Please review the stack for more .....
Exception Details: System.InvalidCastException: Specified
cast is not valid.
-------------------------------------------------------------------------

On the old Server everything works fine.
Any idea?

Thanks a lot
Chris

Did the server move also move it from .net 1.0 to .net 1.1? It is possible
that this is related to one of the breaking changes.

Yes, the server moved from .net 1.0 to .net 1.1.

But what could be the problem?

Can you post the full error message? It should tell you what is actually
causing the problem.

Here is the full error message:

Would appear to be a config file problem. I'd try comparing your web.config
file to a fresh v1.1 config file. I know there were a few changes, but I
cannot find documentation on them and no longer remember what they were.
