WSDL and namespaces

[AK]

Hello,

My OS is Windows XP Professional and my machine was recently reformatted. I
recreated a Web Services application from VS.NET and added web service pages
and compiled the application. The WSDL generated seems to be using a
different namespace than what it was for the same application before my
machine was reformatted.

When I create Web References, I notice that in the new WSDL, type attribute
is using a "tns:" prefix compared to "s0:" prefix in my old WSDL (before
machine reformat).

The code is completely the same as before reformatting. I even tried
creating the asmx pages with same name and just copying the code instead of
adding existing pages to the project.

When a new proxy class is created from the new WSDL, my client application
breaks with an exception that says "Exception in mscorlib: Length of Data to
decrypt is invalid."

Can anyone tell me if the changes I mentioned above coould give the above
error?

I can provide more details if you like. Quick response is much appreciated.

Thanks much,

AK
