Increasing the number of concurrent remote desktop connections is easy. Do the following steps:
Go to “Start” => “Administration Tools” => “Terminal Services Configuration”
Opened up the “Properties” of “RDP-tcp” in the connections tree and selected the “Network Adapter” tab:
“Unlimited connections” is grayed out so in “Maximum connections”, increase the value to whatever value you want.
A word of advice though, if you will notice that you cannot go above the value of 2, this is a licensing issue. Without purchasing Terminal Services CALs, you are limited to at most 2 Remote Desktop connections. So you may need to possibly upgrade your license or get new ones in order to accommodate the maximum number of connections that you want.
By default, Remote Desktop’s port is set to 3389. If you wish to change it to some other port for whatever reason you have, you can do so with the easiest way changing the registry value using a Windows program called RegEdit which modifies registry name=pair values.
Follow these steps.
click START > RUN > type regedit and the regedit program opens up.
navigate to each key starting from
double click the PortNumber key, and choose the decimal radio button to reveal the value set by default as 3389.
change to whatever port number you wish
When connecting remotely using the Remote Desktop Client with the changed port, you can just add a colon + the port number after the domain or IP address.
The client connets to the IP address 192.168.8.XXX with port number 1234.
