NO AUDIO OR VIDEO

[Tor-Eddie]

I've been struggling for the last week trying to get
Windows Messengers Audi/Video functions to work. I'm
running Windows XP Pro, hard-wired into a Linksys WRT54G
router (latest firmware upgrade) using Messenger v5.0.

Have had Linksys tech support help, checked with my ISP
(Covad) for possible firewall issues (none) and searched
high and low for help online.

Tried to activate the UPnP function in XP, but when
running setup I'm asked for a file (upnpui.dll) and to
insert Windows XP Service Pack 1 CD. Since I downloaded
SP1 from MS' web site, I don't have a CD. It doesn't work
to insert the original XP CD either. What do I do?

In the past I was able to accept incoming A/V conference
using XP, Messenger 4.7 and Linksys BEFN2PS4. Not after I
switched to the wireless.

Advice or comments?

If you are still trying to communicate with the same

people and they have not changed either ISPs or Net
Connections, you have probably run into the widespread
NAT/SIP problem. When you changed you probably got
yourself behind a Network Address Translator and/or a
Sessions Initiation Protocol which blocks Video and Audio
connection, either on your side of the Net Connection or
on the other side. So far, no one that I know of has
found an answer to this problem. This does not normally
affect Instant Messaging.

Greetings Tor-Eddie,

Although it shouldn't be required, I'll gladly e-mail you this .DLL if you like, it may help
the problem.

However, here are some other issues to look into -- make sure both you and your contact have
gone through the Audio (and Video) Tuning Wizard in Messenger. To do so, open the main
Messenger window, click the Tools menu, then Audio Tuning Wizard, then go through the wizard
to select and test your audio/video devices.

Then, both you and your contact should verify that the Windows XP Internet Connection
Firewall isn't on -- click Start, then click the Control Panel. If you're in category view
click Network and Internet connections then click Network Connections. Right click your
network/internet connection, then click Properties. Click the Advanced Tab, and verify that
the Internet Connection Firewall is unchecked. As well, if your contact is using some type
of third-party firewall (ZoneAlarm, Norton Internet Security, etc.) have them make sure that
Messenger is set to "Permit All", "Allow All" or "Medium" (ZoneAlarm).

If that's not the case, and if you or your contact are using a router (with UPnP support),
you may need to remove the current port forwardings. To do so, click Start, All Programs,
Accessories, Communications, Network Connections. Right-click the "Internet Gateway" (should
be under the Internet Gateway heading) and choose Properties. Choose the Settings button,
click each 'msmsgs' or 'msnmsgr' entry and then choose 'Delete' to each one. Then close
Messenger (right-click the Messenger icon, choose Exit), then restart Messenger.

Finally, you and your contact might try turning off the QoS Packet Scheduler. To do so,
click Start, then click the Control Panel. If you're in category view click Network and
Internet connections then click Network Connections. Right click your network/internet
connection, then click Properties. Uncheck the QoS Packet Scheduler, then reboot and try
again.

Also, make sure that your contact is able to have an audio conversation with someone else, to
rule out the problem being on their side.
