Xp sp2 sets the limit of concurent connections to 10, if you hit 10 it blocks all the connections for that program, this is supposed to protect against worms and what not but yea it makes your p2p speed suck
To see if you are getting the error
Go to administrative tools - event viewer - and look under system
if there is a yellow sign thingy with tcpip and the event id is 4226 then you probably need this fix...

I take no responsibilty for your computer getting screwed up if you do this wrong.
This fix will make the number of concurrent TCP connect attempts UNLIMITED.
First of all, make sure you backup your old tcpip.sys first!
Restart your computer an press F8 short after the Bios is done and start in safe mode.
Then we go into the directory C:\WINDOWS\SYSTEM32\DRIVERS and overwrite the existing TCPIP.SYS
with our patched one and then repeat this with the directory C:\WINDOWS\SERVICEPACKFILES\I386
and system dependend eventually with C:\WINDOWS\SYSTEM32\DLLCACHE.
We did it! Now only reboot Windows and the normal surfing will work again!
The original fix was made by LvlLord, but that fix only increases the number of concurrent TCP connect
attempts from 10 to 50 which is in some cases not sufficient.
if you want a unlimited number of connections heres the link for that
edit: fixed the link so ya'll don't have to register to download the unlimited one
