March 27, 200719 yr 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?
March 27, 200719 yr 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, 200719 yr by nmX.Memnoch
March 27, 200719 yr 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.
March 27, 200719 yr Author 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.
March 27, 200719 yr Not necessarily.I've seen people mention this hack in reference to just general usage though. It gets me every time...
April 18, 200719 yr 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.
