Dear Gianni
You do not need to setup anything on the sme box except to specify the "number of pptp clients" in server manager remote access panel (at least 1).
With sme server v5.6 apply Update 4 which fixes some pptp problems.
Make sure that your local Windows workstation has 128 bit encryption, all standard instals of Win 95 and Win 98 & Win 98SE require a DUN update, different updates apply to each OS version so make sure you get the right one. Win2KSP2 and Win XP should be OK out of the box. Without the correct encryption installed the VPN connection will disconnect almost immediately.
On your Win PC setup a VPN connection in Networking with a hostname like
www.yourdomain.com (of the remote server).
When you logon to your local PC you must use a username and password that is valid on the remote sme server as well as using the same username and password to establish the VPN connection. Remember to establish your Internet connection first.
To map a drive on the remote server do
net use M: \server IP\ibayname
eg net use M: \192.168.X.X\data
or to map a drive on workstations on the remote network do
net use N: \workstation IP\sharename
eg net use N: \192.168.X.65\station5
Of course you will need to determine the IP of each remote workstation you wish to connect to, using winipcfg or ipconfig (or ipconfig /all). Mapping connections using servernames is not supported.
Hope this helps
