this problem effects win2k and xp and is a windows issue with how failed dns quieries are handled.....due to vladd and pies utter stupidty in allowing RIAA to conect to the wpn and therefore flood the network and over load primaries nt5 machines tie them selves up in knotts trying to connect .......1 st solution is in settins host name resolution instead of using winmx to resolve host names choose the option to use a external source, here simply enter in your isp primary dns server on port 53.....
second solution is to go to this web site
http://www.speedguide.net/downloads.phpand download this patch winxp_dnscache.zip
this will fix this issue.
Description: Patch Windows 2k/XP not to cache failed DNS entries. By default, when a DNS lookup fails (due to temporary DNS problems), Windows still caches the unsuccessful DNS query, and in turn fails to connect to a host regardless of the fact that the DNS server might be able to handle your lookup seconds later This patch fixes the problem by configuring the DNS client to continue sending queries to an unresponsive network.
i have successfully tested this on my beta which has now been online for days with no problems at all,,,,,note it also seems to help with dl and up load timeouts.......long live winmx down with the pie fa****s
