Usefull command line utilities

I decided to put some command line utilities what I use and always forgot here. I will update the list:
Terminal services
works on Vista
qwinsta - query terminal services connection
rwinsta - logoff terminal services connection or any local session

General:
Works on Vista and Windows 2008
query { PROCESS SESSION TERMSERVER USER }

Network:
netstat - Displays protocol statistics and current TCP/IP network connections

* all utilities have help just add /? after the utility name or Google it.

Windows domain time synchronization

I had a problem with a Windows 2003 DC (PDC role), it refused to provide NTP for the domain (despite I did all advised configuration in Registry), so solution was to change GPO for "Default Domain Controller Policy":

Computer Configuration\Administrative Templates\System\Windows Time Service\Time Providers\Enable Windows NTP Server to Enabled.

You need to use windows w32tm.exe utility with different option to diagnose NTP problems on the domain.
