Hello!

I looking for what is the max number of concurrent tcp connections on windows 2012 r2 essential..

I didn'f find answers on here or on the web

Any help wold be appreciate.

thanks

Hi,

There is no official article related to that. However, based on my experience, there is a registry key to define the maximum number of connections that TCP can have open simultaneously.

You can check the key of TcpNumConnections in registry editor under the path below:

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

If there is no such registry existing, you can add one and configure the value from 0x00xFFFFFE(REG_DWORD). (0 means that you cannot establish any connections)

What exactly is your goal here?

This server can't do web hosting

Can't do RDS/TS.

So what's the reason for the question so we can better answer it.
