I recently upgraded workstations at one of my sites from the Zen 4.01
agent to Zen 7sp1. The local IT resource at the site is saying that
since then and not consistently workstation will become practically
unusable. I have the Inventory scan set to run at shutdown, NAL
refreshes every hour. The search policy is limited to the local
container. Is there anything that could have caused it from zen 7sp1,
where as zen 4 never had this issue according to the users.

Any help would be appreciated.
