Increase tcp/ip CONNECTION??

i downloaded and try it....but it does't work...

Exactly what concurrent connection limit do you want to raise?

If XP is acting as a server (file/print, ftp, web, anything else) it is limited to a maximum of 10 unique IP addresses connecting to it.

Sounds like when your using P2P and you reach the limit of 10 inbound connections.

There is a patch here but be warned it could fry your router

The article that  is reference twice now:

http://www.speedguide.net/read_articles.php?id=1497

Has nothing to do with the maximum number of IP addresses that can access a XP computer as a server, which is 10.

The article and patch is about limting the number of outbound connections XP can make going out in a specific amount of time.

A unpatched system can not try to connection to more than 10 systems in a second.  It can connect to as many systems outbound that it wants, but it can't try more than 10 in a single second.  This was MS attempt to slow down how many other computers a infected XP system could try and infect.

hutnor, you need to tell us, is this inbound (XP is limited to 10 and you legally can't change it) or is it outbound.

If outbound, is it to a single computer or more than one.  IIRC all current Windows systems are limited to about 4,000 connection to a single IP address.  There is a registry setting that limits the highest random port to 5,000, which gives you just about 4,000 possible ports (5000-1024).
 

so..wht should i do?

pls help me.....is der any software to solve this problem?

That patch is not working.

You need to describe exactly what you are trying to do.

Again, as a server, XP can only allow 10 other comptuers to connect to to.

As a client it can only have about 4,000 connections outbound connections.

Are these inbound (XP as a server) or outbound (XP as a client)?

The patch does not fix EITHER of the above situations.

If you want to run a server, buy server-class software/licenses (in your case probably from Microsoft), or run linux.  There's a reason you're having problems doing what you want - it's because you didn't pay Microsoft enough $$, in their opinion.

sir,
actually my problem is..
we  developed one software. Which works in LAN.  This software has a server part and a client  part. In server we need to share some audio and video files through our software. In the client side, we need to access that files from server through our client software. This process should works at same time. Now our problem is the server can transfer files upto 10 machine only.  Our OS is windows XP. We can't change it in to a server os.

pls help me..

Sorry you are out of luck.  XP is limited to talking to up to 10 unique IP addresses when it is acting as a server.  PERIOD.  There is nothing legally you can do about this.

MS wants you to get a Windows Server license if you need more than 10 concurrent clients.

There are only two legal ways to get around this:

1) Get a MS Server OS.

2) Get just about any other OS that can act like a server (Linux, NetBSD, FreeBSD, are some examples) and have to serve up the audio/video files.

The problem is ,our software is a windows application.

I think XP SP1 OS has no limitation for concurrent connections.

Now i want to know one thing. Can i use XP SP 1 tcpip.sys file in XPSP2 ????

--> I think XP SP1 OS has no limitation for concurrent connections.

Nope, every version of Windows Desktop OS's (95, NT, 98, ME, Vista) desktop has been limited to 10.  I do beleive that there was a "patch" that would increase/remove the limit.  However, installing the patch was a violation of the EULA.

If you can't use a Linux server to serve up the files, then you must get a Windows server OS, or get a bunch of Window desktops and spread your users across multiple desktops.

How, do you do the actual file transfers?  I am assuming you did not develop your own file transfer protocols, so I am assuming you are using either Samba, NFS, FTP, or HTTP.  A Linux computer can act as any/all of those types of servers.

hmmmm.....i didn't get a proper solution....

i think it is impossible.....

It is impossible because it is illegal.

"i didn't get a proper solution...."

Wrong.  You did not get the solution you wanted.  You did get the proper solution, if you want to stick with Windows, then get Windows Server.

finally can i ask one thing?

if a chenage my XP SP2 tcpip.sys file in to XP SP1 tcpip.sys....what will be the result?
