I'm having some problems with remote assistance. Today a customer requested
remote assistance, which I accepted. The dialog box that says 'connecting to
xxxxxx's computer' was displayed and nothing happened after that.
My PC is running XP Pro and is behind a NAT UPnP enabled ADSL router (ZyXel
Prestige 652-R11). My customers was behind a Dlink DSL-504 NAT UPnP enabled
router.
Later I tried some experiments between my PC and my laptop, both
disconnected from my router and dialled into to different ISP's, both with
ICF enabled on each dial-up account. I was able to perform remote assistance
each way with no problems, although it was very slow being on dial-up.
When I request remote assistance from my laptop (on dial-up) to my desktop
PC behind the router, the laptop is able to take control, but the other way
around it will not work.
I read in knowledge base article 301529 that if both novice and expert are
both behind a NAT that remote assistance won't work if you are using Windows
Messenger, but that it would work if 'Save Invitation as a File' or the
'Send Invitation as an E-mail' method is used when the expert is behind a
NAT.
I'm going to do some testing, but it seems like a strange limitation. I
though perhaps there's a problem with my router, but now I'm not sure!
