Hi, I’m doing a POC on Report Builder 3.0 Map Wizard. I’m using spatial data from AdventureWorks2008 and selecting Sql Server Spatial Query as source of spatial data in report builder 3.0. Now when I’m checking Add Bing map layer in Choose spatial data and map view options screen I’m getting an error as – The request failed with Http status 407: Proxy Authentication Required(The ISA Server requires authorization to fulfill the request. Access to web proxy filter is denied.). After saving the report when I try to run it I get an error as – The name dev.virtuaearth.net could not be resolved. Please note that I’m behind a proxy server. So, I did some modification with the Web.config file of Report Server and added the below piece of code to resolve the above error – <system.net> <defaultProxy enabled="true" useDefaultCredentials="true"> <proxy bypassonlocal="True" proxyaddress="http://myproxy:port"/> </defaultProxy> </system.net> After I did this modification the error “The name dev.virtuaearth.net could not be resolved” that I was getting when I ran the report went away and I’m now getting another error as – The request failed with HTTP status 502: Proxy Error(The ISA Server denied the specified Unified Resource Locator(URL)) when I’m trying to run the report. The other Http status 407 error is still there in design view of the report. So to summarize –I’m getting Http status 407 error in design view and Http status 502 error in run mode. Let me know If I’m missing out on something like Bing Map account or MapPoint Account or something like that or if there are some pre-requisites that I might not have taken care of. Please help me resolve this issue.Sourav

Hi SouravDeep, Generally, in order to avoid “The remote name could not be resolved:’dev.virtualearth.net” issue, we can add above settings between </runtime> and </configuration> nodes in the web.config file. Based on my research, the Http error 407(Proxy Authentication Required) indicates the connected client was not authenticated. The Http error 502 occurs that if a site and content rule in ISA Server is configured to only allow certain content groups. For more information, please refer to the article below: http://support.microsoft.com/kb/831140/ Personally, I think you should focus on the proxy server configuration and the firewall. Thanks, Bin Long

I added the following code between </runtime> and </configuration> in the web.config file fo report server- <system.net> <defaultProxy enabled="true" useDefaultCredentials="true"> <proxy bypassonlocal="True" proxyaddress="http://myproxy:port"/> </defaultProxy> </system.net> But it didn't solve my problem. It only changed my error message from "The name dev.virtuaearth.net could not be resolved" to "The request failed with HTTP status 502: Proxy Error(The ISA Server denied the specified Unified Resource Locator(URL))", when I try to run the report. I'm not sure what is the exact problem and how I can solve this. Any help would be appreciated.Sourav
