Every time a user logs into their workstation, which of course is first thing in the morning, a backup application runs that copies their ID, names.nsf and a few other files, to their network home directory as a backup. Works pretty well. Too well. Seems that people are so excited to get into their Notes and start their day that they don't wait until the files are done copying. So while the files are in use by the app being copied to the network and the Notes client launches trying to access the files, bad things happen. But when the leave Notes alone until the backup is complete, everything is happy happy.
Another day, another problem solved.
