Hi,

I work with netmeeting connecting 2 computers by phone line
and modems without internet. The first computer is
configured with a incomming connexion. The second computer
dials up to connect to the first computer. Then the second
computer establish the netmeeting connexion using the first
computer name.

I used this process hundred times with two windows xp sp1
computers and all worked fine every time.

I've updated the first computer to windows xp sp2 and now I
encounter big troubles. No problem with the computer
connexion but :
- the netmeeting connexion is slow
- sometines the connexion of the two whiteboards is slow or
impossible
- when I disconnect netmeeting from the second computer, it
seems that the first one doesn't know that the connexion is
closed
- sound delay or losses
- etc...

It seems that these troubles are not related to windows sp2
firewall (I shut down firewall and nothing changed).
Moreover they are random troubles, sometimes they appear
sometimes no.

I tried to change the services configuration but I didn't
find a sure solution : sometimes adding a service seems to
solve the problem but when I try again the troubles appear
again.

So, my questions are :
- what services are necessary for netmeeting with sp2?
- what services are harmful to netmmeting with sp2 ?
- did the troubles come from the fact that one computer is
under sp1 and the other is under sp2 ? (but I worked with
success with netmeeting between xp sp1 and win 95 !)
- perhaps another configuration problem ?

Thanks for your answers,

Pascal

A common problem on upgrade to SP2 is caused by the enabling on the "QoS
Packet Scheduler" for the connection. I am not sure if that could be an
issue here (I am not even sure if it can be used on a dial up connection)
but it might be worth looking at.
(http://radio.weblogs.com/0127028/2004/10/18.html has some information on
disabling).

I can't think of any other SP2 changes that could be issues.

Thanks for your answer. I'll try it tomorrow but one thing
is currious :
I've ben using netmeeting with students and windows xp sp1
and I've tried to disable all useless windows services on
their computer (it was to lighten their computer, increase
the speed and avoid conflict problems). I observed that
(with windows xp sp1 and dial up connection) QoS was
necessary : when disabling QoS there was no sound in
netmeeting. I'm supprised that QoS is necessary under sp1
and harmful under sp2 !

But I'll try. Thanks.

Generally this is not a good plan in my opinion -- it usually creates more
problems and conflicts than it could possibly cure.

The suggestion is not disable the QoS service but to disable the binding to
the "QoS Packet Scheduler" in the NIC. This problem(with QoS Packet
Scheduler bound) can happen in both SP1 and SP2 though it seems the
triggers are different in the SPs.

It's also shadowed for the outgoing connection. It seems
that QoS is needed for a direct connection by modem between
two computers : the box of QoS is checked and shadowed in
the connection properties window of the two computers.

OK. See my other message. I thought QoS was necessary for
NetMeeting but I think now that QoS is necessary for the
direct network connection by modem between the two
computers (the box of QoS is checked and shadowed in the
connection properties window of the two computers). Maybe
there's no solution for me under sp2.

So the modem has the QoS Packet Scheduler in the bindings in its but it
cannot be deselected?

OK. I try to explain it. Thanks for your help.
First of all, let me tell you that I use a french version
of windows so I'm not sure that my translations in english
of the dialog boxes are the right ones.

On the first computer there's an incoming connection.
[This connection was created with the "New connection"
assistant : fourth choice "Configuring an advanced
connection" ; "accept incomming connection" ; only the
modem is selected for this connection ; no VPN ; a user of
this first computer is selected.]
In the control panel : double-clic on "Network
connections", right clic on the incomming connection icon
and clic on "Properties", "Network management" tab, and the
QoS Packet Scheduler is in the listed elements below "This
connection uses the following elements :", it is selected
and shadowed.

On the second computer there's a outgoing connection to the
first computer.
[This connection was created with the "New connection"
assistant : second choice "Company network connection" ;
"remote access connection" ; a name and a phone number ;
then the user name and its password is asked at the first
time connection is used.]
In the control panel : double-clic on "Network
connections", right clic on this outgoing connection icon
and clic on "Properties", "Network management" tab, and the
QoS Packet Scheduler is in the listed elements below "This
connection uses the following elements :", it is selected
and shadowed.

I didn't see any place where QoS is linked directly to the
modem but only places where QoS was linked to connections
used by the modem.

OK I guess that makes sense. It may all be a read herring(the QoS issue)
though and not worth pursing further.

I don't know what is the source of your problem.

though and not worth pursing further.

I think I've found a solution. I tried a thing that seems
to work.

On the first computer, the one with sp2 and with the
incoming connection, I uninstalled the link to QoS Packet
Scheduler in the "Network management" tab of
the "Properties" window of the incomming connection. In
fact, this uninstall the link to QoS for all connections
of the computer.

Netmeeting seems to to work well now. I tried a dial up
internet connection from this computer, it works well
without QoS.

The QoS RSVP service is still in manual status in the
service management console but it doesn't start.

What's the role of QoS if everything works (better)
without it ???

On the second computer with the outgoing connection, the
QoS RSVP service (in manual status) starts with the
connection.
On this second computer, I did'nt try to uninstall the
link to QoS because I use this computer with ten students
who work with xp sp1 and I don't want to get troubles with
that ten connections. But, when I can I'll try it.

Best regards,

Pascal
