WSE2.0 Security Exception ? -- dotnet web services enhancements

Hi,

I think the root of the problem lies in the security area. You are
getting a "Request for the permission of type
System.Net.DnsPermission.... failed".

Are you running the Client app in something else than full trust?

Hope this helps,

Hello,

I've been wrestling with getting a WSE2 enabled client installed on a
Windows 2003 server. It works from other machines (not 2003) but not
this one. I created a test application that consumes the same web
service, instead of my production application, and I get the exception
below.

What does this mean? How do I solve this problem?

Thanks,
-Ben

Hi Marvin,

I'm running both apps (production and my test app) off of a network
drive. I have permissioned them both with full trust via the .NET Wizard.

Thanks

Anyone have any idea why I would get errors running an app from a
network drive, but enabling the app to have Full Trust? I have no
problem running the app from a local drive.

This problem seems to be specific to 2003, as I can permission the same
executable with full trust on a Win2k box without error.

Thanks,

Hi,

One more thing that jumped into my mind (i donno if its relevant
but...) I know there was a change in drive mappings for different user
accounts in W2K3.

Are u using an UNC path?

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

Hi,

I'm using a mapped drive, when I reference the network executable. For
now, I have this issue resolved by running my app from a local drive.
Hopefully we'll be able to run it on a W2k3 networked drive eventually.

Thanks,
-Ben

The app I am using is running on a local drive. The error occurs when the app
(a windows service) attempts to read the app config file. The app has admin
permissions, so I do not believe that is an issue.

I did notice something strange however. In Win2000, when attempting to read
the app config file, whitespace is detected, which could explain the
exception. In XP, no whitespace is detected at all. I am still researching
why this is the case. Thanks for your response.

Regards
