Win2k Machine contacting Root Server???

[Alex <incidents () alex gotdns org>]

Hi,

I recently ran "netstat" on my personal laptop (running Win2k) and was 
shocked to see that it had been making TCP connections to the root servers 
(to their domain port). I know that some DNS queries are performed using 
TCP, but I find it somewhat disturbing that the root servers were 
involved.

I did a little googling and found a few remarks that Win2k machines 
sometimes do this...   But mine has the lastest updates....

So I'm a little concerned.  Is this normal operation for a win2k machine, 
or could something more amiss be going on?    Norton Antivirus and SpyBot 
Search & Destory didn't find anything wrong.

Thanks

(I realize this is probably a normal thing,  but I still find it 
disturbing)
