Re: WSE2.0 Security Exception ?

Hi,
I am getting the same error here, but from a windows service application
that is simply trying to read its app config file. The service is able to
read its config file on my development machine with no problem, However, on
a Win2000 machine I get the exception.

The first thought was permissions, however I am running my service under an
administrator account. The problem (to me) appears to be when using the
System.Xml.XmlNode class. Below is a copy of the config file the app is
reading and the code that reads it (sorry for the poor formatting). Any
help, or thoughts are appreciated.

Regards
