IPAQ remote access to XP machine via GPRS

I have an HP IPAQ running MS Pocket PC 2003 with a GPRS modem inbuilt. While out of the office, I would like to be able to access my network and read email (Exchange server).

One idea was to utilise an analog modem hanging off an XP Pro machine. Could this be a viable solution - if so, how would I go about configuring the IPAQ & XP Pro machine for remote access? Then how do I go about accessing the shares & Exchange server from the IPAQ?

Many thanks in advance for your comments, tips and ideas.

what provider do you use for your gprs service? this will probably influence your decision to use gprs (or csd - circuit switched data) or not as some carriers charge for data transferred. just so you know, in actual usage you will probably see only 30-40kbs on gprs while seeing 9.6kbs over csd.

if you decide to go the gprs route, you are already online so you can type in an address and get to your xp machine (barring port restrictions/firewalls on the carriers side and your side).

We use Deutsche Telekom/T-Mobile as a provider.

The XP machine is not visible to the outside world. The network has a dynamic IP address it receives from it's provider, so without using dyndns (or similiar) to gain access to the network, configuring the firewall, setting up a VPN etc., it would not be possible. Also, lots of work here.

That's why we thought dialing directly to an analog modem on the back of the XP machine - a quick and dirty solution - but not really sure how this would work. The iPAQ has an intergrated phone in it. Thanks for your comments.

sure, no problem. then your only option would be to use csd and dial directly to the modem hanging off of the xp machine.

setting up your "call" to the box is simple, it is just like dialing any other number. you will need to make sure that data is enabled on your account (at least here in the states it is not always set up and has to be requested via t-mobile) and that you have some sort of terminal services/vnc/tightvnc setup on both your ipaq and xp machine.

may i suggest some additional resources in helping you get this setup?

these may give you some additional information, especially with setting up (at the very least) vnc on your handheld.
