When you select the server and click Restart in the IIS Manager console, the Terminal Services Gateway service will be stopped and not restarted, even though the World Wide Web Publishing service is restarted. If you are logged into the server via RWW or a TS Gateway session, your connection will be dropped and you will not be able to get back in via RWW or TS Gateway. In addition, the following event will be logged in the Microsoft-Windows-TerminalServices-Gateway/Operational log.
Log Name: Microsoft-Windows-TerminalServices-Gateway/Operational
Event ID: 400
Task Category: (3)
User: NETWORK SERVICE
The TS Gateway service is shutting down. To diagnose possible causes for this problem, verify whether the following services are installed and started: (1) World Wide Web Publishing Service (2) Internet Authentication Service (IAS) (3) RPC/HTTP Load Balancing Service. Also, check Event Viewer for Network Policy Server (NPS) and IIS events that might indicate problems with NPS or IIS.
Keep this in my mind when working in IIS Manager on the SBS server remotely. Use iisreset /noforce instead or restart the World Wide Web Publishing service in the Services console.
