Derek,
I had the same trouble with Windows Messenger Live 8.0 and tried all
the fixes mentioned in the various newsgroup threads, including the
following:
Router Setup:
- enable UPnP
Windows Setup (on both host and client computers):
Windows Services:
- ensure "SSDP Discovery Service" is running and automatically started
- ensure "Universal Plug and Play Device Host" is running and
automatically started
Windows Firewall:
- ensure "Remote Assistance" and "Remote Assistance - Windows Messenger
and Voice" are checked in the "Exceptions" tab
I configured all these on both the host and client computers and it
still didn't work, I kept getting the same message "Remote Assistance
connection disconnected. Please try again."
The critical item for me was this: my Netgear router supports an SPI
(I think this is Stateful Packet Inspection) Firewall as and added
security feature. I think most of the newer routers do (I've seen it
on a Dlink too). I had to turn this off in my router settings and it
finally worked. My Netgear has a "Disable SPI Firewall" checkbox under
"WAN Setup", the box was unchecked as default and I checked it. I am
still operating behind the router and have not had a chance to test it
from the internet. I will post an update to this thread when I do.
