I "accidentally" ran chown and need help

I'm trying to set up a backup for a client machine running 8.10 Ubuntu using an Ubuntu 8.04 server running 2.6.1b1 - but the version on the client machine is an earlier one.

Anyway, I fat fingered something and changed the ownerships on all the files in /usr/libexec/amanda and I'm now getting an error message that says

Amanda Backup Client Hosts Check
--------------------------------
ERROR: 192.168.1.102: [/usr/libexec/amanda/runtar is not SUID root]
Client check: 1 host checked in 0.091 seconds. 1 problem found.

Right now, I have that set to root:disk - I basically copied the same permissions from the /usr/libexec on the server. Here's the directory with the owners/groups

ls -lh /usr/libexec/amanda
