Hi All,

I hope this is the correct forum for this problem, apologies if it isn't.

At present, I can easily remote access my server, using RDC, as both the server and my PC are permanently connected to the Internet. I connect to other PC's using UltraVNC but again, both are permanently connected to the Internet. I have a need to remote access a PC that is connect to the normal phone line via an ordinary 56K modem. This remote PC is not permanently connected to the Internet, I need to be able to dial into this remote PC as and when necessary. There is nobody physically near this PC so it cannot be connected from that end.

Has anyone had this problem and, if so, what's the solution? I've looked at PC Anywhere but it's expensive and a number of people on the forums seem to prefer VNC.

not realy sure i understand it.

am i correct that you are asking how you can force an offline PC to somehow connect when you see fit?
if that was possible, then this would be extremely insecure and a lott of bad people would exploit it to force your off-line machine to dial in and drive your phone bill through the roof.

making the connection will always need to be initiated from the offline machine (for instance, a little scrip that executes a dialer, requests a page that returns a 'stay connected' flag (or connects and reads form a db) and then disconnects or remains connected, depending on the flags value. this script could run automatically (using a CRON or scheduled task) every few seconds/minutes/hours.
you could then change the flag when you want the PC to remain connected and wait until the script has ran.
so you then aren't exactly saying 'connect now' --> you'll need to wait till the scrips is ran (depending on the frequnecy of your cron/ST, this coul mean a delay of a few seconds/minutes/hours).

of course, this can be a very expensive sollution if you need to pay your ISP some standard fee for each connection...

<edit>turns out the remote PC runs XP Pro so setting up a RAS-server and allowing it an incomming connection from your home PC is probably the way to go.</edit>
