Dear friends, 

        I am trying to create a web application to produce some 
statistical result using R. In order to avoid high CPU usage of  web 
server caused by R, I have to create an ASP.NET web service in another 
server to involve R. 

        But I am facing the unauthorizedAccessException when I call the 
web service, even I have assigned access and launch permission to everyone 
using DCOMCNFG.exe 

        The sample code is shown as below, and the 
unauthorizedAccessException  exception is occurred when myR.Init("R") is 
        myR = New STATCONNECTORSRVLib.StatConnector 

        Does anyone know this solution and please advide me?  Your help is 

With Best Regards, 
WeiQiang Li
