Hi!

I have a strange error in a console application that is hosted by IIS 5.0
and invokes a web service hosted on the same machine.

A request form the web comes in and it is dispatched to a service class
which uses a helper class to create an instance of the automatically
generated webservice proxy class. The instance creation fails on this row:

_10._0._40._252.ETISXTeeService srv = new
ETISXtee._10._0._40._252.ETISXTeeService();

with this exception:

System.ArgumentException: Illegal characters in path

the full stack trace:

Error: System.ArgumentException: Illegal characters in path.

the same webservice is correctly invoked by a test client created using
windows forms.

Of course I have googeled, but i have yet to find a solution :( any help
would be appreciated
