What is the difference between Microsoft VPN and Cisco VPN? Are they just separate implementations of the same protocol?
I seem to remember hearing somewhere that they were not compatible with each other, and I have never seen any one connect to a given network with both clients…

Microsoft VPN is usually PPTP, Cisco uses IPSEC. These are completely different protocols so a client won't typically support both.
Microsoft also support L2TP and more recent versions do support IPSEC, although the implementation is a bit clumsy (imho).
PPTP has had several bad security problems in the past, but the latest version is reasonably secure and is easier to set up than IPSEC.
IPSEC is more of an industry standard and is very secure when configured properly.
