10 Connection Limit reached without any network connection

[Sven Erik Matzen]

Hi,

I've a development machine with winxp prof. for development of iis
applications. From time to time I've the problem that my IE tells me (while
testing my application on my local machine) that the limit of concurrent
connections is reached. How can this be with no network cable plugged in?
I'm using the same port (HTTP 80) for all request to the local IIS. I know
that IE is cunsuming multiple connections when connecting to an http server
(which is different to the documentation at KB122920).

Another thing about this: KB122920 tells me that a session is built for
every "transport level connections" - does this include inbound
TCP-connections to 3rd party services? We have a service that needs to be
accessed by multiple PCs directly using TCP/IP-connections (this "Main-PC"
is the reference PC for licensing and will be connected by the software to
query the license information), so I have to tell our customers if they need
to invest in a Win2k-Server OS.

Thanks,
Sven

no, i run a 3rd party telnet service that is similar to a chat server. it
typically runs with 70-80 users connected at a time. it also handles a
dozen or so connections on other ports incoming and outgoing to other chat
servers in our network. so its not a tcp/ip stack connection limit. that
machine also runs iis and still can serve 10 incoming users there.
