Orion Platform

Cause

An AntiVirus software blocking the creation of new sockets.

Resolution

Check the total number of of open sockets.
Run the following command from an elevated command line in Windows:
```
netstat -nao | find /i "ESTAB" /c
```

This will give you the number of connections. The default maximum for windows is 16,384. If the total open is below the default then the Anti Virus software can be blocking.

Remove the Anti Virus software or reconfigure to prevent it form blocking the creation of sockets.
Restart the server.
