SP2 patch KB884020?

[Gnaedinger, Greg [SKY:QZ12:EXCH]]

I already posted on this topic (attached below), but thought I'd repost with
a specific reference to the SP2 patch KB884020. It is this patch that was
recommended to resolve the problem of calls dropping through NetMeeting.

Any insights into the recommended Microsoft patch KB884020? Is the use of IP
addresses in the 'loopback address range' relevant to connecting through the
VPN using desktop sharing (NetMeeting/Timbuktu)?

Thanks!

Hello,

Regarding frequent call/connection drops using Timbuktu, NetMeeting, (VNC?)
after SP2 installation...

I contacted Microsoft about this problem. I use NetMeeting through a VPN
to remotely control my work-based PC desktop. Same problem: after no more
than a moment of inactivity in my session, the NetMeeting call is dropped. I
enabled the firewall logging and saw that indeed it looked like the
connection was forcibly closed.

Anyways, the reply I received from the MS tech was to install the following
patch:
http://www.microsoft.com/downloads/...d2-5034-4bbb-b74d-ad8430a1f7c8&displaylang=en.
Overview:
"This update helps resolve an issue on computers running Windows XP Service
Pack 2. Programs that connect to IP addresses in the loopback address range
may not work as expected and you may receive an error message indicating you
cannot establish a connection."

I haven't yet tried the patch, and am hesistant. It doesn't seem to describe
the same symptoms (i.e. the problem is not that I cannot connect...only that
the connection is forcibly dropped after a very small window of inactivity).

Does anyone have any comment on this MS patch? I don't know what is meant by
the 'loopback address range'. Is this relevant to connecting through the VPN
using NetMeeting?

Thanks in advance!
Greg

Hi

Why not just install KB884020 and see if it helps, and if not, just
uninstall it again if you feel hesitant to have it installed in
that case.

Possibly. The loopback address range is 127.0.0.0/8, but without that
patch all but connections to 127.0.0.1 are blocked which would match the
behaviour you describe.

The patch itself consists of just one file, actually and I haven't encountered
any problems so far. Or in other words it's not a very intrusive patch and
if you wish to uninstall it later on this won't much of a hassle in any case.

Cheers,
