Re: [NetMeeting] Problems with NetMeeting 3.01

[Stephen Wenzler]

Alright, I'll look into this and see what I can do and I setup my 
account as admin by default and you are correct that I have Windows 2000 
Pro with SP4 installed.

I'll let you know if I can find the cause of the problems :) Thanks for 
your best efforts!

http://www.intel.com/pccamera/portals/testcall.htm has a test call setup (or
used to). I haven't tried it for a long time so it may now be defunct. If
you are behind a router though it definitely will not work. But as I said
you probably should leave the internet connection out of your test as it
complicates the situation.

I am not sure what Win2000 (is this Win2000 pro?) looks like "out of the
box" (I don't think there should be any policy settings that restrict
NetMeeting). You can check policy settings by running "gpedit.msc" from the
"Start" ->"Run" menu (assuming you are logged into an administrative account
-- are you trying the calls from an administrative account anyway?).
NetMeeting policies are in the Administrative template section ( of both
user and system).

Re: [NetMeeting] Problems with NetMeeting 3.01

Okay, Yes, I scan all the ports above 32767. and I left the settings in 
both ends by default like it comes right out from box the only need to 
set is the video and audio sources and intification info like my name 
and email addresses. Also I have tried to find a test site that I can 
call and test but unfortunely, there is none out there that I can verify 
and do 'loopback' test.

I am not sure what you are saying here or how the cell phone figures into it
(or how you did a port scan across the internet to your laptop) but I
suggest you leave over the internet connection out of the tests and your
thinking for the moment (as it brings a whole other set of possibilities
into the problem).

Is the call you connect on a data only call? 

A data only call would occur if:

1) you initiated a secure call or if you or the other end only allowed
secure calling. This could be done by setting policies at the Win2000 end or
could be initiated by user settings in the tools->options security tab. It
is also possible to have a version of NetMeeting on Win98 created in the
resource kit that forced this but I suspect that is not the situation in
your problem.

2) a data only call was specified. AFAIK there is no way to force this from
NetMeeting directly -- it can be done by using a callto:+av=false url
(probably not in your case though)  or could be forced by policy.

3) it would occur if some other program was using the H.323 ports (are you
running some other phone type program at either end?)

Re: [NetMeeting] Problems with NetMeeting 3.01

[Stephen Wenzler]

I'm back, I peformed port scan to verify that both Windows 2000 and 
Windows 98 are on my local LAN are able to communicate though the known 
ports and it turns out to be fine also I did the port scan across the 
internet to my laptop with cell phone and it has passed the test.

I do not know why Netmeeting wouldn't send out video/audio both within 
LAN and outside of LAN. it is a odd problem.

Re: [NetMeeting] Problems with NetMeeting 3.01

I have used DMZ on Windows 2000 and it didn't work at all so I'll try 
connecting my two PCs together to see what happened, I'll just set the 
IP addresses to fixed addresses so I can trouble-shoot and will get back 
to you when I have more info :)

Going through a router is always a problem for NetMeeting audio/video- I am
not sure what "disabling the firewall" in your router situation means but
generally to get two way audio video in a router setup (i.e. through the
router to an outside station) requires the router to have the inside
NetMeeting computer designated as the dmz machine (different routers use
different names but the majority use the "dmz" designation) so that all non
directed traffic to the router will get forwarded to the dmz machine.

That doesn't explain though why a LAN to LAN connection does not appear to
transmit audio/video. As I said the only thing that comes to mind in that
situation (the router settings should not affect you there) is a local
software firewall setting. There is an issue that can occur with the QOS
Packet Scheduler (http://radio.weblogs.com/0127028/2004/10/18.html) but as
far as I know that is an XP only issue.

Re: [NetMeeting] Problems with NetMeeting 3.01

[Stephen Wenzler]

Okay, I tried to disable the firewalls both router and software and 
tried it again and no help at all, on the windows 98 machine it does not 
have camera nor audio card installed -- it is a very basic system so the 
only PC have camera and sound are on Windows 2000 machine. the model of 
the camera is Phillips PCVG675K  also I noted in Windows 98, it has 
Microsoft TV/Video connection in the network properties so I am not sure 
why the 2K machine won't send video nor audio to any machines on the LAN 
even outside of the LAN though router. I do not know if you experience 
this kind of problems..

If you can see local video then the camera and NetMeeting are working
together.

I can't think of any reason why on a local LAN you cannot transmit
video(calls to outside from behind a NAT router or firewall generally have
no audio/video incoming unless the router is specially configured -- but I
presume from your information that the call was completely behind whatever
device connects you to the internet?). I presume that audio connection also
does not happen? What about the other way -- do you receive audio and/or
video on the Win2000 machine?

If a data only call were forced that would mean no audio/video between the
machines (the most common reason for a data only call would be a "secure"
call - is it possible a "secure" call was made?). The only other possibility
that comes to mind is interference by a local software firewall on one
machine or the other.
