Today , I found my server could not be connected by Remote Desktop Connection. Google + Baidu , One solution is feasible:

1. Telnet the server
2. Show all user (use "query user" on the console interface)
3. Logoff unwanted user, OK!

But, unfortunately, my telnet was not open ! at last, MS SQL Server helped me faultlessly. Share the way with you:

1.Open the "Query analysis"
2.Input xp_cmdshell "your command words" ( As the solution)

Powerful xp_cmdshell, fearful xp_cmdshell !
