When I run 60 second virus scan from Bitdefender I always see a section
in it about Open Ports on this XP box where svchost is using a Port.

The entry says it is Listening on Port 135 and I start worrying because
I remember reading on GRC.COM something about Port 135 shouldn't be
used because it could be used by something nasty.

Last night I was poking around in my Admin Account by clicking Tabs and
Advanced buttons and found out something about RPC.

Client for Microsoft Network Properties says something about
RPC Service and has two choices:

Windows Locator and DCE Call Directory Service

Windows Locator is what I saw that was selected on that setting.

I'm going to look in XP Help & Support to learn something about RPC but
I thought to also ask here to see if someone can clarify the issue for
me, thanks.

... Any task worth doing, was worth doing yesterday.
