When trying to use Small Business Server 2011 Remote Web Access we get this error, if I reboot the SBS server it will start working again for a day or so. Any suggestions on where to start troubleshooting?

"An unexpected error occurred, Please try again. If the problem continues, contact the person who manages your server.

The first thing to look at are the event logs on the server. See if there are any errors or warnings.

You didn't state when exactly that error is occurring (ie, what feature of RWA causes it to occur), but I suspect it may be when accessing a workstation remotely?

The answer to this problem is well documented:

Oh, and if it's not when accessing a computer remotely, there are a few other causes:

(RWA is essentially the same in SBS 2008 and 2011, so the article applies)

Ok, I finely found sometime to get back to this, sorry for the long delay

In Event Viewer I see Event ID 3 WebHost
Here is what it details, please advice:

System.ServiceModel.Activation.HostedHttpRequestAsyncResult/27625033
   System.ServiceModel.ServiceActivationException: The service '/Remote/BuiltIns/RDP/RemoteDesktopWebService.svc' cannot be activated due to an exception during compilation. The exception message is: Memory gates checking failed because the free memory (524255232 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.. ---> System.InsufficientMemoryException: Memory gates checking failed because the free memory (524255232 bytes) is less than 5% of total memory.

So, next time you close out a question -- please don't split points when someone just repeats what was already said.

Thanks.

Tried this fix on my system and it didn't help. I did an iisreset /restart and it fixed the issue...for now.
