RDP service running, but not able to create connection - Windows

Content
RDP service was listening the port - 3389, but rather RDP client, connection failed, I had to run a vmware console.
C:\Documents and Settings\Administrator>netstat -an

Active Connections

Proto Local Address Foreign Address State

TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING

To identify why RDP service was not normal, ran "qwinsta". Looked that was holding sessions when connecting it each time.
C:\Documents and Settings\Administrator>qwinsta

2 關機
3 關機
rdp-tcp#3                                                          4     閒置     rdpwd

To solve it, I, simply, rebooted the server because of scheduled for Microsoft patches.
