We currently have over 3000 Registration Rules set up in ZCM.

Is This too many?

We have 12 Primary Servers, and Probably only about 5000 pc's so far in the system. We stopped as the system is really unstable. Most computers will stop getting policies. Stop getting bundles, etc etc.

I just want to know if the system can handle this or is it screwing everything up.

3000 rules is because every machine goes into a group for a printer. We have around 3000 classrooms. So 1 rule for a class.
