I created a Workstation Import Policy that was set to import workstations at
system startup. Was working fine all morning. The last workstation to be
imported based on this schedule was at 12:30. Next, I noticed workstations
that had been logged in for a few days were not importing into eDirectory.
So, I changed the policy schedule to run at 2:30. The Workstation Import
service was running on my server. 2:30 came and went...no workstations were
imported at that time, particularly the ones that had not been imported into
eDirectory to begin with.

Any ideas as to what might cause this?
