An av (mcafee is on here btw) or firewall would be what I suspect normally, but it's only on the TS servers. So could it be the ac protocol itself isn't getting through? When tested, a whole lot of mcafee connections come up on time wait. So... time to look into the mcafee settings. BTW, xpsp2 is what's being run here.
EDIT: Turned off Mcafee, and still freezes. Another odd thing is that 2 q2 instances come up in the taskman, but still only one r1q2.exe thread.
