NAV2009 addin with webservice, losing connection...

2mas

Hello Everyone,

I am facing the issue - NAV2009 add-in's web-service connection fails because of Proxy Authentication is required.

Maybe someone already faced the same issue before ? I will try to describe in more details bellow.

NAV Setup: Service tier is on Separate machine, all RTC Clients are used from the same installation folder.
All users have same permissions.

I have developed the add-in for NAV 2009 (first C# project ever) .
It is small .dll which lets user to connect to from NAV Page to the 3rd party web-service and retrieve addresses by sending only the post code.

So the thing is that our client uses citrix. Some of higher priority users such as admins can use it without any problems,
But simple users cannot connect to web service, so when this connection to web service fails, RTC client loses the connection.
I’ve inspected from server side, that application on its crash returns the error Message: The request failed with HTTP status 407: Proxy Authentication Required.
I have no idea what the different authentication or setup they are using, as their sysadmin says that everything is the same.

Also what I figured out, while web service call is not made, dll works fine.

Info from Event Log on Server Side:
