I noticed the same behavior when I switched to Vista. Even though I
thought I setup the Firewall filter correctly, the firewall log shows
a set of three entries each time I experience this delay, all similar
to:

2008-02-27 06:34:53 DROP TCP fe80::3058:c71:b98e:3118
fe80::3058:c71:b98e:3118 55686 2401 72 S 37720
02297 0 8192 - - - RECEIVE

I believe it has something to do with IPv6 name resolution, possibly
network name resolution.

If my older Win2000 laptop or older XP desktop is powered on, I don't
seem to experience the problem.

I have also seen the problem by trying to ping my box using the
machine name. Pinging 'localhost' does not seem to exhibit the problem
though.

Another observation: if I run Wireshark (network sniffer) first, I
don't see the problem.

Maybe someone with more IPv6 experience can provide some more insight
into this problem.
