microsoft last update for winxp sp2 changing "tcpip.sys" file. even you patched tcpip.sys with no limitation version , last update replacing it with limited version(10 tcp/ip connection limit). this is very bad for ed2k network users. you must eliminate it with a new version patch from lvllord's tcpip.sys patcher. othervise your emule performance will decrease dramatically. dont miss that.
.download tcpip.sys patcher
filename is "EvID4226Patch.exe" . you can find in ed2k network , use search. first , apply all microsoft updates from official microsoft website, then use "EvID4226Patch.exe". all limitations is gone
