Apache, there are two possibilities I can see.:
One is your network card, the UDP lost session to TCP followed by a hard lockup indicates there may be a hardware failure, driver failure, or some sort of software failure on the windows network layers. Do you run any personal firewall software?
Second is your cable hookup itself. The best way to describe cable is to compare it with a network hub vs a network switch. A cable segment is like a neighbourhood LAN. Other users on the segment can have a massive effect on your connectivity. If possible run a tracert with a package like visualroute or pingplotter. However, don't use the standard settings, change the packet size to 1024 bytes, and set it to 1000 iterations and see if over a long period of time (30 mins) there are any unusual network hits.
One last possibility, is if your aren't running a firewall of any type is some cretin on your segment running DoS attacks.]
In HTCs defense, I run AH from NZ, without any problems. I used to have a Celeron 1Ghz GF2 system, I recently upgraded to board and CPU to go to Athlon 2100XP GF3 system, neither had any major problems with recent iterations of AH (apart from the Ki67 CTDs).
