Two possible/practical answers here
One is to setup a VPN connection from the remote location to the sme server, then you can open server manager in a browser, as if you were on the LAN.
Second is to setup a secure tunnel using Putty, via ssh connection and say port 443, then open your browser to
http://localhost/server-managerSearch the forums for how to do this, it is pretty simple to configure in Putty
It looks like this in the Putty Configuration under Connection, SSH , Tunnels, forwarded ports
L443 localhost443
Obviously you will need to install Putty (ssh program) on the remote workstation, but you could carry it around on a USB stick, along with the secure key file that allows passwordless access to the server (using the ppkey). I think there is a Howto about using public private keys.
The second method is very secure and is my preferred choice.
