L2TP/IPSEC laptop to Mikrotik server vpn

I have read manuals and the forums and for some reason cannot get my head around how to do this. What I am looking for is:

Laptop (dhcp address) ------> Router to internet -----> Internet ----->(public wan 1.1.1.1)Mikrotik server(private lan 192.168.100.1/24)

I would like to create a L2TP/ipsec vpn route from the laptop to the mikrotik server. I can get pptp to work no problem just unable to get l2tp to work. Not sure if this makes a difference but latop is using vista ultimate atm.

Anybody able to throw me a bone as to where to go on this. If just a basic idea as to what i need to do would be great help also.

Try to use this example,
