I wrote a bash script to do it and run the script every monday morning. We use 14 day DHCP lease times so doing this once a week seems to do the trick for me. I have over 3,200 computers in my ARD and it was pretty much unusable before this.
If anyone is interested, here's my script. Use it at your own risk, etc. Works for me though.
#!/bin/bash
SCRIPT_VERSION="1.0"
# verify ARD Admin version
# quit ARD Admin - if running, wait 10 seconds
# kill cfprefsd
# rename plist
# sed
plist_path="$HOME/Library/Containers/com.apple.RemoteDesktop/Data/Library/Prefer ences"
plist_name="com.apple.RemoteDesktop.plist"
plist_backup="com.apple.RemoteDesktop-backup.plist"

major_version=$(echo "$version" | cut -d. -f1)
minor_version=$(echo "$version" | cut -d. -f2)
bugfix_version=$(echo "$version" | cut -d. -f3)
if [[ "$major_version" == "3" ]] && [[ "$minor_version" == "7" ]] && [[ "$bugfix_version" == "1" ]]; then
