Hi, I am making calls to WCF services on IIS7. After I make a call using a REST call from the ArcGISDynamicMapServiceLayer Map Service (esri.arcgis.client.dll) I get an NTLM authorization error to any future WCF calls. Do you have any suggestions on how I can get around this?  Looking at Fiddler it seems like the Map Service is removing the NTLM data. Thank you in advance for any suggestions.
