Finally I understand

This is what I have Done:
1. At the Office where the SME Box Resides on the Router make sure you Port Forward Port " 1723 " to the SME Box.
2. On the Office SME Box " Security / Remote Access / PPTP Settings " type in the amount of Users you need to have VPN Access to the SME Box eg. 2 or 55 etc. and then click " save "
3. On the Office SME Box " Collaboration / Users " go to the User (Yourself or admin or whomever) and under Modify choose " VPN Client Access "
for that user and change it to " yes " then click " save "
4. Make sure you know what your SME Box IP Address is eg. " 10.0.0.50 " or whatever it is that you installed it with. Also as Previously stated the Windowz PC that you created the VPN Connection must be on another IP Range eg. 10.0.
2.10 <---Windowz PC IP Address.
5. At the REMOTE PC (Your Home or Client's Windowz XP outside of the SME Lan) goto " Network Connections " and then " Create a New Connection " making sure that you choose " Connect to the Network at my Workplace " and enter the Name of the Connection, Your SME Box User Name and Password. After you have Created the VPN Connection just click on the Connection that you just created on the Windowz PC and you should be connected to your SME Box.
6. On the Windowz PC just open the IE Browser andf type in the Host Name (or IP Address) of the SME Box eg.
https://smebox/server-manager and you have Lift Off. Full access to the Server Manager.
Thanks Guys.
SME Server is Simply GREAT
