Greetings Mark,
Firstly, make sure you've 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, 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're 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 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..
