Temporary Solution:-

This is the error i came across OnCommand running on windows 2008 R2 server.

The solution is to increase the connection in windows 2008 server.

1) Open the windows command line and check how many ports are opened.

C:\>netsh int ipv4 show dynamicport tcp

Protocol tcp Dynamic Port Range

---------------------------------

Start Port      : 49152

Number of Ports : 16384

2) Increase the number of ports with the command

C:\>netsh int ipv4 set dynamicportrange protocol=tcp startport=5000 numberofports=60536

3) confirm again

C:\>netsh int ipv4 show dynamicport tcp

Protocol tcp Dynamic Port Range

---------------------------------

Start Port      : 5000

Number of Ports : 60536
