Hello guys.

We have an installation of SCSM 2012 SP1 running well, however we have two remote sites with low speed (<2mbps) WAN links.

Over those two sites, the Self service portal opens but the Silverlight content does not load. It shows the [Arg_TargetInvocationException] and when I look into the trace file on the client PC it shows this:

Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.0.20125.00&File=mscorlib.dll&Key=Arg_TargetInvocationException ---> System.TimeoutException: [HttpRequestTimedOutWithoutDetail]

Is there a setting I can tweak to increase the timeout for the portal's HTTP requests?

Is this really a timeout issue? When I ping the portal server, ping is 50ms on average which, despite the lame WAN link, is pretty decent.

Thank you.

Tomas

EDIT: I forgot to say that the portal works fine over the LAN. The problem arises only over WAN links.

The full error stack is this:

And it definitely shows a timeout exception.

Anton, I tried what you said, however it is still timing out.

A few minutes ago, during lunch time the portal did open over the WAN link, so it does seem to be related to latency or channel saturation, however, it won't open again, so the problem is not the initial load but also consecutive ones.

The silverlight object does not seem to cache on the local PC.

EDIT: I set the timeout to 20 minutes as you suggested but the Silverlight box times out after less than a minute. Am I missing something?
