Can't invoke web service - error 500

[account]

I'm getting an error 500 everytime I try to invoke a web service.
Everything is running local on a Win XP machine. Any suggestions?

Thanks,
Brett

It could be something in the code you are writing.
Create a web service that does nothing but reply by a string, and see if the
error 500 still persists.
