SyncCenter prompts error: "System net sockets exception: only one usage of each socket address is normally permitted.", why?

[Product Manager]

The error message means that some other processes are using the VCOrganizer's ports.

VCOrganizer uses UDP broadcast IP 255.255.255.255 port: 11000 for service discovery, and port 8182 for data communication

In the future release, we will allow user to change the communication ports.

In the meantime, you can try to find out which process is using the ports and then stop or kill the process from Windows Task Manager. Here is the netstat command that you can run from your Command Prompt to find the processes,e.g.:

C:\>netstat -ao

Active Connections

Proto Local Address Foreign Address State PID
TCP 0.0.0.0:8182 cow7:0 LISTENING 2508
UDP 0.0.0.0:11000 *:* 2501
.....

In this example, the process 2508 and process 2501 are using the ports.

In your Task Manager, select "View -> Select Columns .." from the main menu.
In the "Select Process Page Columns" windows, make sure the "PID(Process Identifier)" is checked.
Then, in the Task Manager, try to locate the process from process table in the Processes tab and kill it.

Start the SyncCenter again.
