Unable to request remote assistance

[paquette]

Since I reinstalled SP2 (critical updates installed) on my XP Pro
home-office machine from the full installation file I have no problem
accepting remote assistance calls from others. Tonight, however, I
wanted to show my daughter something on my machine and tried sending
her a remote assistance request to that end. She accepted the call and
the remote-assistance loader got as far as the "connecting to" message
but I never saw anything at my end. I am behind a NAT router by port
3389 is forwarded.

I have tried sending a remote assistance request from a laptop on the
same home LAN. It worked! Whatever it is, it is specific to my main
home-office machine and it has survived a complete reinstallation of
SP2 from the full installation file.

Does anyone have ANY ideas????

What if any software Firewalling do & your daughter use ? Did you
have her check the ticket and verify that a uPNP of WAN IP was
in the address and not a LAN Routed IP>

Thank you for your prompt response!

The only active Firewall is the one in the router with 3389 forwarded.

uPNP is enabled on the router. What "ticket" are you referring to?

 

[R. McCarty]

On the recipients end, the RA Assistance file itself. It is a "Flat"
text file which can be opened with Notepad or Wordpad. In it
will be the RA Source PC's IP Address. If uPNP is enabled, it
will translate the LAN (Router IP) to it's outside WAN (Internet)
address. If the recipient gets a non-translated IP, such as one
like 192.168.2.2 the ticket cannot be resolved as the IP will not
be found. In that case you need to inform the person using the
ticket what your WAN IP Is and modify the ticket accordingly.

Thanks again--potentially very helpful!

File name or location?

I presume you are referring to the assitance file attached with an
invitation by email. If that is the case and it contains a
non-translated IP, how would one prevent the use of an untranslated IP
both for email-initiated sessions and for invitations directly from
remote assistance itself?
