I got a error log(event id:1020) from our DHCP server and said "Scope,
192.168.1.0, is 84 percent full with only 64 IP addresses remaining" . We are
only 30~35 PCs in this subnet now, should be still have over 200 IP can be
used. There are no related information provided about how to solve this
problem on Microsoft website.

Any ideas about how to solve this problem?? Thanks a lot

It's an informative warning

"There is no means to customize this threshold for this event through the
registry because a value of 80% is hardcoded"

The IP's scavenge from the database every 4 hours after their "grace period"

One point that maybe worth checking is whether any machines have RAS enabled
that could request extra IP's. Also are some machines laptops that have
wireless and wired connections?
