I had the same issue when upgrading.  I also tried uninstalling and reinstalling, with no joy.  What I eventually discovered was that the log (C:\Program Files\ArcGIS\Server\framework\etc\service\logs\service.log) was saying (upon startup): Found flag file C:\Program Files\ArcGIS\Server\framework\etc\upgrade.txt. Starting in upgrade mode. So I renamed that file to upgrade.txt.old, restarted ArcGIS Server, and voila! Manager and admin page suddenly worked.  Problem solved. I don't know why it wasn't starting, but that at least got me to a fresh, functional installation. ... View more

Isn't the System.Action Anonymous and takes 0 args? would we have to create a new delegate with a Graphic set as one of the args.... ??? I have been trying to get this to work for days now and still can't seem to get this thing going 😞 System.Action is anonymous in this example, but it can take an argument (or more than one, if needed; see the link), so it doesn't need to have a delegate. ...

No problem, glad I could help.  I know we're not the only ones facing this. FYI, since I posted the code, I've refined it somewhat for our needs.  We created another application for which I used the same basic code, but we also needed HTTPS, request interception, plus a couple of other bells & whistles. My point is that if you have issues getting the posted code to work, shoot me a message and I can dig up the updated code for you. Plus: LOL. ... View more

I couldn't figure out how to use Fiddler with an authenticated proxy, since Fiddler overrides the proxy settings itself.  However, I think I know what's going on anyway, for the most part: client -> proxy: request proxy -> client: 407 authentication required client -> proxy: authenticate proxy -> client: 200 OK client -> proxy: request proxy -> server: request server -> proxy: 200/401/404/whatever proxy -> client: 200/401/404/whatever ...or something like that. Regarding overwriting the WebRequest, that would require access to the WebClient, which isn't there. At this point I suspect that the API functions are using a standard WebRequest; however, if you were to create your own standard WebRequest behind an authenticated proxy, it will automatically pick up the proxy server and port, but doesn't automatically set the credentials.  That must be handled by the specific implementation.  It can be retrieved from default, but isn't automatically set.  The problem here is that since the API doesn't expose the WebRequest object (which in turn exposes the Proxy object, which in turn exposes the Proxy.Credentials object), we have no way to set the proxy credentials to respond to the 407 response from the proxy. In the end, our solution was to build a small TcpListener-based proxy into the application, which will pick up the default credentials (or we can specify them) and pass them to the real proxy.  We then set the ProxyURL on all of the API objects to "http://localhost:port/" established by this local proxy. This works, apparently quite well so far, but it would have been significantly easier if the API had allowed for proxy authentication to begin with.  On a side note, it's worthwhile to know that we tried HttpListener first - this was a bad move, as HttpListener has some serious security issues and requires administrator actions to make it usable on each client.  Not cool.  Anyway, I can post code for the proxy for whomever is interested. ...

Thanks for your reply, Jennifer.  However, as I stated, this is NOT a silverlight application.  This is WPF, a thick-client desktop application.  There is no web server to server a proxy page from. See this comment on the page you linked.  It says : [...] this will not work in WPF [...]. The services and tasks available in the WPF API offer only a string ProxyURL property, without any proxy authentication properties.  The Credentials property doesn't work for a proxy, it is for authenticating with secure ArcGIS services, not the proxy itself. So - what options are available for WPF? Edit: For clarification, here is the summary: 1.  WPF desktop application - no web servers involved 2.  Proxy, requiring authentication to get anything from the internet 3.  Non-secured ArcGIS REST endpoints (in this case, we're just using ArcGIS Online) ...
