User can't accept calls - window does not appear on screen |
|
|
A user is running XP SP2, NetMeeting 3.
When someone tries to call to the user PC, one can see the phone calling
(ringing) the user. However, the user on the other end does not see the
person dialing in order for him to accept the call. The small window showing
the phone ringing in order for him accept does not appear on the screen.
I've removed and re-installed netmeeting and that didn't help. I've moved
the PC to anonther network port where I know it works and I still have the
same problem. I have isolated the problem to the PC.
The user appears on the directory and he can call anyone and the other
person accepts calls with no problem.
Only when they call him, he can't accept calls. The windows that appears
allowing him to accept calls does not appear on the screen.
Any thoughts?
Thanks in advance!

How are you making this call? Are you sure you are calling the correct
computer?
Is the called computer behind a router or border firewall and the caller
not?

If the problem is truly the PC (I am guessing though that wherever you
moved it too is behind a different router so that the problem is still that
the user is behind a NAT and not reachable)-- then the only thing I can
think that might be an issue is a local software firewall blocking the
incoming call. Is NetMeeting set as an "exception" in the XP SP2
firewall(it would have to be to allow incoming calls)?

The most likely cause is that the called computer is behind a NAT router or
firewall of some kind and cannot be called. A local firewall not configured
to allow NetMeeting server or exception access would have a similar affect. |

Well I appreciate your reponse but I know for a fact it has nothing to do
with NAT routers or firewall. The reason I know this is because we have over
3000 PC's in this company and we've seen this on 4 other PC's. The only way
we've been able to fix it is to re-image the PC's. We set the PC's back to
the same location and it works fine again.
The only thing that is consistent with these PC's is that they are all
laptops. One of the 4 had window 2000 installed. We also disable the
firewalls on the XP machine.
This is why I know it is PC related and nothing to do with the network.
Might sound like a network but we've gone through here. We've even moved the
PC to a location where netmeeting is working and once we try calling one of
these laptops, the caller doesn't see the call come in. He can connect, the
calling window just doesn't appear.
Oh well, once aigains thanks.

How are the calls being made?
I can only think of these possibilities (assuming NetMeeting is running
waiting for the call on the target machine and there is no interfering
network device):
- you are not calling the machine you think you are (the IP address used to
make the call is not the correct one). You could try a direct call --
determine the IP address of the machine (via the help -> about in
NetMeeting) and call directly to that IP address
- there is something on the machine blocking incoming calls -- tcp 1503 and
tcp 1720 are the two listening ports for NetMeeting - a local firewall,
IPsec setting could block incoming calls

calling window just doesn't appear.

The physical location of the device is possibly not the determining factor
-- the IP address of the device and default gateway would determine the
virtual location in the network. How are IP addresses assigned in the
network? Are the IP addresses in the problem machine determined using the
correct method. |
