AFAIK, this limit doesn't apply for TCP/IP connections, only netbios

I know that NT4 Workstation only allows 10 concurrent network connections. I
didn't think that limit had changed for Win2k Workstation. Even though your
app is running on the same machine, it is still making tcpip requests which
would count against the limit. This is to force people to buy NT Server.

Subject: Connection refused under hight load 

I'm testing a servlet-application that is using Tomcat v 3.1 
without Apache) running on Win2K Workstation. 
The tool I'm using for testing starts a (configurable) number of 
each of which connects to the server, sends a HTTP-request and waits for 
the response. It runs on the same machine as the server. 
When I start many threads simultaneously, the server sometimes refuses 
connections (I get a ConnectException on client side). 
The tomcat logfile shows nothing unusual. 
Does someone know a possible reason for this behaviour or even a 
solution ? 
(I suspect that the "connection request queue" (I don't know the correct 
 term ) of the operating system is too short, but where can i adjust 
this ?) 

Thanks in advance,
