Unable to increase the dynamic port range on Windows Server 2008
Solution 1:
You have to run:
netsh int ipv4 set dynamicport tcp start=32765 num=32765
This would set your dynamic port range to start at port 32765 and go through port 65530 (32765 ports)
Solution 2:
Try netsh int ipv4 set dynamicportrange tcp start=32767 num=32768
