Article Summary: This article provides information on an error that may occur when you attempt to connect to a remote machine via Remote Web Access (RWA) in Windows Small Business Server 2011.
You may receive the following error when trying to connect to a remote machine through Remote Web Access (RWA) on a Small Business Server 2011 server:
This computer can't connect to the remote computer because the Remote Desktop Services Gateway server is temporarily unavailable. Try reconnecting later or contact your network administrator for assistance.
In this situation, you will be able to log into the RWA page without a problem; the error will not appear until you try to use RWA to connect to another machine on the network.
There are several possible causes of this problem, one of which is that a third-party Web application has been installed on the server and has enabled 32-bit application support on the DefaultAppPool application pool in IIS. To see whether this is the case, follow this procedure:
If Enable 32-Bit Applications is set to True, this is probably the cause of the problem. Setting the value to False will likely fix it, but this will also break the third-party Web application. If the Web application can't be removed, check with the application's vendor to verify that it requires 32-bit support. If it does, see the following TechNet blog entry for instructions on getting the application to run properly: How to Run a 32bit Web Application on SBS 2008/2011 Standard.
If 32-bit application support hasn't been enabled on the default application pool, the issue may be caused by incorrect authentication settings on the RPC virtual directory. The supported authentication methods on this virtual directory should be set to Basic and Windows authentication, but Exchange may be causing it to revert to Basic authentication only. To fix the issue, perform the following steps:
