I would expect more than this because we have a large network, approx 32 
class C's and some private address ranges as well.  The machines in the 
Open Access rooms have short leaases, approx 20 mins, as some leases are 
'stolen' if a student plugs a laptop in.

Also, a lot of the machines where turned off over Christmas, so the 
leases would have expired, therefore I would have expected a lot of 
updates when these new leases were allocated.

When it was working, all the files had corresponding .jnl files, now 
only two files have them.

Is there any way to force a client to release/renew it's lease from the 
server end?
