Windows 7: Remote Assistance over net doesn't work

Remote Assistance over net doesn't work

Tried asking for help in the Networking forum, but nobody would reply, so I thought I'd try here before giving up altogether.

Twice I have been unable to make a connection to offer RA to a friend. Our basic system specs are as follows:

Both have DSL (different providers).

My end: Windows 7 Pro; Linksys WRT54GS (v6) router with UPnP enabled; Windows firewall set to allow RA.

His end: Vista HP; a Netgear WGR614 (v7) router with UPnP enabled; RA allowed in firewall.

We can easily establish a chat connection using Live Messenger (latest version). I suggested on both occasions that he request RA from me via Messenger. After entering his RA session password at my end, it is unable to make the connection. Only vague, general possible reasons for failure are offered by the RA software. Microsoft offers a connectivity diagnosis tool online, but it is not compatible with Windows 7, so I cannot run it for reliable results on my box.

Reading in "Windows 7 Inside Out" (published by Microsoft Press) about RA, it notes that with the advent of Vista, RA is supposed to easily traverse a pair of NAT routers to link a pair of computers. Well, apparently not in my case, which is why I'm asking for help here.

Maybe I'm just too bleary-eyed from frustration to see where I'm missing a critical setting either within Windows (Windows 7 & Vista) or in router setup. Can someone guide me through steps most likely to make this work?

I should note that I have subsequently tried TeamViewer, and did successfully link to my friend's computer, but I would still like to have RA available as an alternative.

Thanks in advance for any help offered.

Making some headway...

Alright, so it occurred to me to "just try something, anything" in hopes of finding a clue. My desktop consistently fails when trying to initiate a RA connection via the Easy Connect method (either to Invite Someone, or Help Someone). It churns for bit, then returns with "Easy Connect is not available .....Can't connect to the global peer-to-peer network ."

This usually leads to a suggestion to run MS's Internet Connectivity Evaluation Tool, resulting with a "Not Supported" for the NAT Type test, and "Not Run" for the UPnP test. UPnP is definitely enabled in the router (actually, in all three of them I've tried).

So, for the hell of it, I tried a household laptop (Windows 7 too) via wireless to the same router (currently D-Link DIR628). Easy Connect on the lappy succeeds every time in linking to the "global peer-to-peer network". It either presents me with a password to convey to my "helper", or a RA terminal waiting for me to enter the "requestor's" password. Weird. Good, but weird.

If I run the Connectivity Tool from the laptop to the same router, it returns a "Supported" result for NAT Type, but still "Not Run" for UPnP. At least something seems to be working right.

Now the obvious question would be why my desktop cannot do the Easy Connect thing, but the laptop can, with same OS and behind the same router. There must be some software setting in 7 on the desktop at fault. I briefly enabled a wireless adapter in the desktop (then pulled the ethernet cable), but had no success, so I think I've ruled out a quirk with the ethernet (my normal connection to router).

Any ideas?

Ok, so I decided to scour through networking related settings, comparing my laptop and desktop side-by-side. Found one thing:

Network and Sharing Center > Change advanced sharing options (on left pane) > Public > Public folder sharing --on the lappy Turn on sharing so anyone...... was checked. On my desktop Turn off Public folder sharing was checked instead. After changing that one setting on the desktop, magically Easy Connect began working--my desktop will now find the "peer-to-peer network" when trying the Easy Connect option. I was easily able to use my laptop to "request" RA help from my desktop via Easy Connect, and vice versa. Would not work before. I have not been able to try a RA session to another computer across the net and behind its own router yet, but I suspect it will work now provided the other computer and router have appropriate settings.

Edit: And now the Internet Connectivity Eval. Tool test categories all result in "Supported" for my router after making that small settings change. Problem seems to be solved on my end.
