I know merely having an ipv6-capable Linux system makes libc go down the AAAA track. I don't know what OS you are using, but disable ipv6 and reboot and see if that fixes it.
Under linux, "echo alias net-pf-10 off >> /etc/modprobe.d/blacklist-ipv6.conf; depmod -a" and a reboot will totally disable ipv6 Also, getting wireshark up first would allow you to check without guessing. If you see bunches of AAAA lookups that timeout - that's definitely your problem -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
