mau-yong Posted March 27, 2007 Posted March 27, 2007 Since I cannot find a connection limit (to add more than 10 simultaneous connections) patch to tcpip.sys on Windows 2003 Server, I tried the old LvlLord's patcher and it seems to be working.I also tried to confirm this on xp-Antispy by clicking on the menu Special -> Connection Limit... and it already shows 50 connections and looks patched nicely.Can anybody confirm this using other means?
nmX.Memnoch Posted March 27, 2007 Posted March 27, 2007 (edited) The limit is NOT for 10 simultaneous connections.The limit is for 10 simultaneous half open connections. You want to limit those because it can be a DoS vector... Edited March 27, 2007 by nmX.Memnoch
nitroshift Posted March 27, 2007 Posted March 27, 2007 Being a server platform, Windows 2003 does NOT have a limit of 10 concurrent connections, but as nmX.Memnoch said, 10 half-open connections and yes, they SHOULD be limited.
mau-yong Posted March 27, 2007 Author Posted March 27, 2007 The limit is for 10 simultaneous half open connections. You want to limit those because it can be a DoS vector...Oops... I had a totally different "grasp" on tcpip.sys patching. Thanks nmX.Memnoch and nitroshift for clearing this for me.You mean 2003 SP2 would still be considerable fast (also for file sharing) even if I don't increase the "10 simultaneous half open connections"? I don't know if it's just me, but I noticed just a little bit of decrease in network performance after I upgraded to SP2.

I don't know if it's just me, but I noticed just a little bit of decrease in network performance after I upgraded to SP2.Yes, it will still be fine. To be honest, I'm not even sure if Server 2003 has this limit imposed (although I would think it would).The network performance drop that you noticed was probably because XP SP2 turned the firewall on.
TheTripleX Posted March 27, 2007 Posted March 27, 2007 But isn't it recommended to have this limit to 50 - 100 when using P2P programs?
nmX.Memnoch Posted March 27, 2007 Posted March 27, 2007 Not necessarily.I've seen people mention this hack in reference to just general usage though. It gets me every time...
eXtermia Posted April 18, 2007 Posted April 18, 2007 Half open connections being limited does however limit the speed in which I do vulnerability scanning (Harris Stat Guardian and Retina) .So I do patch my TCPIP at least I did in XP Server seemed to have been higher limit but I haven't checked as of SP2.
