Re: Remote Desktop
Hi Paul, hopefully I can clarify a few things for you.
First of all, when you say your home computer is connected via a router to telstra ADSL... is this router independent of the ADSL modem and you installed it, or is it the only device between your computer and the phone socket? If it is the latter, it is not essentially acting as the router Gordon was suggesting. I believe Gordon was referring to common SOHO routers that have NAT firewalls in them, which can prohibit externally sourced traffic such as Remote Desktop. In fact it would've requried extra configuration for Remote Desktop to work at all, and since you did get it to work via your mate's computer, we'll assume it is just acting as a modem for now.
What Gordon was implying is that the modem at your house, and the similar one at your mate's place, allow open communication to pass both ways. That is, everything that is sent to the IP address will go to your computer for it to deal with. If you have no firewall installed, this can be a strong security risk. However at work, it is likely that they have implemented high security firewalls to protect from intrusions. In doing so, they block all activity that wouldn't be commonly used by users of the network. Thus, when your remote desktop client attempts to connect to your home computer, it is likely the company's security will stop any communication between the two computers because it is not common traffic.
If it is necessary for you to utilise remote desktop from work, I suggest you talk to your network administrators as Chris suggested.
In future, when using a support forum, try not to repeatedly ask for a solution; the questions from Gordon were to assertain your situation and just because he didn't give an answer straight away doesn't mean he isn't working on it. Sometimes questions can take a couple of replies to answer.
I hope this helps with your understanding.
Ollie.
