How to resolve the issue that a message indicating port occupancy is displayed when the U2000 is upgraded by means of patches on Windows 2003?
The message does not display the process that occupies the port. Therefore, perform the following operations:
1. Enter CMD in the Run dialog box and run the netstat -aon command to view the PID relevant to the occupied port.
The following message is displayed:
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING 1692
2. In the Task Manager, click the Processes tab and choose View > Set Columns. In the dialog box that is displayed, select PID.
3. Locate the process corresponding to the PID on the process side and end the process if the process is not used any more. Then, the issue is resolved.
