XP Pro concurrent connection limit.

Hello EEs,


I have installed XP Pro SP3 to give connections to my 18-20 users to access some share folders.
But whenever more then 10 users are connecting it is giving error:-
"No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept."
Then i start googling i came to know that it is a limitation of Client OS & i need to install server to solve my problem,

Since I have setup every thing & I want to use XP Pro which can serve to all my 18-20 users.

Kindly advice how can this be done with doing any registry changes or any other idea?

an earlier reply will be appropriated,

Many thanks

are you using simple file sharing if it is true then you need to disable it by going to tools>folder options view at last uncheck box the box "use simple file sharing" and now share the shares as you like

after disabling simple file sharing you will get option of "maximum allowed"

However if you are using the XP Pro box as a server then 10 concurrent connections is the maxmum permitted under the licencing terms for the operating system.

Good day,
Windows XP Pro is designed to only accept 10 incoming connections.

you can use a software to give access more then 10 computer the link is right here


This software does not use Windows file sharing, so that limit is not applicable to it. My Remote Files works on Windows 2K, XP. It creates HTTPS or HTTP server that can be accessed from usual web browser.

3rd party software, or a HTTP or FTP server is indeed the only way to overcome the license and real restriction of 10 users.

Something used sometimes, but flaky, is to limit the connection idle time to one minute. That should shutdown idle connections very soon, but introduces more issues than it is worth it, IMHO. The issues are "I have accessed the file some seconds ago, now I get this same error message. I have retry several times!":

net config server /AUTODISCONNECT:1
This is a limitation of the OS (as MASQUERAID already stated) , and it is a violation of the EULA to increase the amount of connections, by modifying system files, hence NOT LEGAL.


Those types of hack posts are not allowed here.

Buy a server OS. Thats al there is too it, the only LEGAL way to do what you want.....
Actually, it is a violation of the EULA, as it changes the way that a machine can be caccessed. This limit is imposed on each version of XP, 5 being home and 10 for professional.

The tcpip.sys patch removes the 10 connection LICENSED limit for inbound connections. If you want more than 10, you have to buy a server OS.....

My mistake on that patch though. I thought it was the other modifed TCPIP.sys patch that allowed more than 10 INBOUND connections. That one IS a hack and should not be posted, as it is a violation of the EULA.

"But whenever more then 10 users are connecting it is giving error:-"

Thats the patch that applies to this scenario......

Thanks to all of you to join me here & sorry for replying you late since i was on sick leave,

I read all of you valuable commands, what does this commands mean:-
"net config server /AUTODISCONNECT:1"

Kindly advice is it the last way for me to buy a server or what is your advice for 2-3 TB NAS.......any suggestion / idea?

Many thanks once again,

Are you sure you dont mean

""net config server /AUTODISCONNECT:-1""  <~~~ Notice the -1

-1 would configure the Server service to not Automatically disconnect connections to the server hosting the shares. 1 sets the auto disconnect at 1 minute, so if you configured this on the server hosting shares, then after 1 minute of activity they would be disconnected.....

"... after 1 minute of activity ..."

That should read "... after 1 minute of inactivity ..."
D'oh.... Ty.... :-)
