Land Rover Repair: Rolling in park, and water leak, watter, water leak

Question
I just purchased a used '98 Discovery and I love it.  The only major probles I've noticed thus far is a problem with being in park and a small watter leak.

1.  When I am on any kind of slop at all (even less than 1%) and the truck is in park it still rolls.  It has been suggested that a cable may just need to be tightened, but I'm not sure how to do that.

2.  After a STRONG rain last night I noticed some watter leaking in at a slow rate just above the mirror in the head liner.  Is this a leak in the seal around the sunroof making its way down?

Thanks for the help.  It's good to be in the club.

Answer
This is out of my area, but the cable you are referring to is probably the hand brake cable.  When it is in park the transmission should stop any rolling, there is probably something minor wrong with your transmission.

The leaks is most likely the sunroof seal.
