I would like to know how Remote Administration works. I know how to enable the windows firewall and what remote administration clients/MMCs are available, but I am wondering what services/processes are in concern at the remote server. Is there a specific windows service listening to remote administraton calls (which could be stopped using net stop)? Thanx in advance. Regards, Chris

There is a combination of services that work together to enable remote administration. Core services such as RPC, DCOM, WMI are needed to allow remote administration and also depending on what task you're performing other services will also be required e.g. for managing remote registry the Remote Registry service must be started. WMI relies on DCOM when used to connect to a remote server, access to TCP port 135 is required. Then, a dynamic TCP port opened by the WMI service is used for WMI requests. If a specific ports range for RPC services was configured on the remote server, ports dynamically allocated to DCOM servers are included in the range, including for the WMI service. Therefor I don't think you could stop a single service in order to disable remote administration of a computer. Sachin Gadhave (MCP, MCTS)

Hello, That depends of the remote tool itself. Just to add to Sachin reply: For AD, you can actually administer it using Powershell since Active Directory Web Services service is started (Like with Active Directory Administrative Center). Needed port is mentioned here: http://technet.microsoft.com/en-us/library/dd378856%28v=ws.10%29.aspx So, the conclusion is that it depends of the tool you are using because they are based on various technologies.
