Communication Problem

Post by RU1M » Wed, 05 Dec 2007 03:05:01


I am trying to use messenger between two Vista Machines. The invitations go
out and area accepted. The person trying to accepts inputs the passwords.
However no prompt comes back. When the roles are reversed (i.e. I request
assistance), and the password is provided their computer tries to connect to
mine (requesting assistance). It gets an error that the connection cannot be
established. Does anyone have any suggestions on how this can be resolved.
I thought it might be a firewall issue but even when I lower the firewall it
does not seem to work. I cannot seem to get the diaglogue box with the other
persons desktop.

If there is anyone who has an answer to this, any help would be appreciated.

Thanks

Hi EML,
I'm having same problem and have posted a question on this forum. Jonathan
Kay replied and said that one thing one can do is to go into task manager and
end process mrsa.exe and try again. I think there is more to the problem than
that so I'm sure discussion isn't over yet. I also connect with XP machine
from same Vista desktop and don't have some issues although not perfect.

Hi Nick.....Tried that, still does not work. Do you think it might be a
firewall problem. My feeling is that it is not since I have dropped all the
firewalls when using this and it still does not work. In this case it
actually does work the other way. When I have the other person request the
assistance, rather than me offer it they get as far as their computer trying
to connect but I again see nothing. Their computer comes back and says that
it is unable to establish a connection. Than ks very much for the response,
I hope that we both find something on this one.....it has been driving me
crazy for the last several days.

Hi EML, I don't think it is a firewall problem either as on occassions, often
after a reboot, it works. Did you end process on both machines or just on the
one? I haven't tested it myself as it was Jonathan Kay that gave me the
advice same day. I have similar problems that might relate to this one. For
example it happens quite often that I cannot access the Internet from MSN
Messenger, IE7 and Skype, yet Windows Live Mail can! Running the Connection
test suite in Live Messenger I get report that there is a problem with Key
Ports. I've tried all kinds of things like turning off firewall (Mcafee) etc
but cannot solve problem. I thought perhaps it was a problem in my Router
(Netgear) but other machines going through that router seem to be OK.

reetings Nick,

This is on Vista right? If so, what you're describing is usually a incompatibility with
Vista's new network auto tuning feature.

To turn off this feature, open up an elevated command prompt and type the following:
netsh interface tcp set global autotuninglevel=disabled

If you're unsure what I mean by an "elevated command prompt", this explains it:

onathan,

Yes it was on Vista? I've typed the command in so I'll have to see what
happens over next few days. I'll let you know. How long will that command
last? If only until I restart machine then is there a way I can go through
Network & Sharing Centre to set it up permanently.

Many thanks

Nick

i Nick,

It's permanent. The only way to turn it back on is to go through the process again with
autotuning=enabled.

i Nick I have seen the discussion between you and Johnathan. I will also
try this. The word I got back from microsoft is the enabling of the 3389
port. Did that and it also does not appear to work. I will try what
Johnathan is suggesting although I am not sure whether this will work. I
will let you know.

Nick:

Do you have the port 3389 enabled? If so did this work for you?

i Johnathan/Nick:

I tried you autotuning and it dis seem to work. However, the other person
can see my destop but when we reverse roles I cannot see their desktop. We
have disable tuning on both computers and have adjusted the ports 3389. It
is very strange that it seems to go one way but not the other. Any ideas that
you might have would be greatly appreciated.

Thanks Johnathan/Nick

Hi EML and Jonathan,

First of all I have to report to Jonathan that the autotuning=disabled
problem did not cure my problem. I still get the situation whereby IE7,
Messenger and Skype cannot access the Internet but Live Mail can. I will try
EML advice with the port if someone can tell me how to open it up (I use
Mcafee security center)? I'm slightly unsure about this option as I don't
think Skype uses same port as IE7 and Live Messenger.

Hi Nick and Johnathan:

Well I got half the problem fixed. Nick, when I got both people to open
port 3389 one person got through no problem. This was suggested by
Microsoft. Still having problems from my end. The other person is OK. I
have sent a diagnostic file to Messenger support so that they can run a
simulation and see what the problem is. That is the best that I have for
now. If you get any further I would appreciate if you let me know. BTW te
autotuning did not work for us either.

I'm still investigating my communication problems so have decided to look at
System Event Logs that McAfee security center keeps. First of all I can
report that Port 3389 has been marked as open all the time. However if I look
at the inbound events under System Services log I see UDP ports in
31000-60000 range being logged and no doubt blocked. Maybe Jonathan knows
what these might be?
