What is the Default Maximum Number of TCP Connections on the serve

What is the Default Maximum Number of TCP Connections on the server ?

Can this be increased and how ?

Recently, we experienced an unusual delay in starting our application.
Using the NESTAT command, I can see over 100 TCP connections in various
states.

TIA

100 does not seem like "squat" to me.

Maybe the limitation is the Application,...and it probably is not the number
of connections specifically,...but rather the amout of load created by all
the connections combined,...which is going to be related to what the users
are actually doing within the Application at a particular given moment.

Re: What is the Default Maximum Number of TCP Connections on the s

Acutually, there are more than 500 TCP connections (as per NETSTAT).

Is there a Registry entry that limits the number of TCP connections and can
it be changed ?

Hi,

If you are still looking for a possibility to alter the number of
TCP connections:

In HKLM\System\ControlSet\Services\Tcpip\Parameters

MaxUserPort:
Increase the number of TCP ports to allow more open ports.

TcpTimedWaitDelay:
Decrease the number of seconds, until a TCP port is released (down to 30).
