This is a very typical problem with LAN and Roadwarrior types. Especially
when your dealing with static IP's. As Tim Brody stated, the ip/netmask is
being associated with the NIC card and not the PPTP tunnel. 

Another alternative that I use (especially for non-technical management
types) is to create a separate windows hardware profile. i.e. Office/Remote.
Then in Windows Device Manager -- disable the Ethernet NIC for the "Remote"
hardware profile.

This approach has the usual pluses/minuses associated with it. 

PLUS: It fixes this problem by not initializing the NIC at boot up.
Dialup/PPTP and TCP/IP stack still function normally.

MINUS: When the user turns on their PC/Laptop, they will now be prompted to
select the appropriate hardware profile before windows fully boots. The way
I explain how to correctly answer this additional prompt to the non
technical managers types... Ask yourself the following question: "Where are
you powering up your Laptop? The Office or are you Remote?" So far, even the
most computer illiterate can correctly answer this prompt.
