We have noticed that several of our users often will get logon errors if
they try and sign in to the NW client/Windows as soon as the logon box
appears. If they wait say 30 secounds, it runs fine. I have been told
that even though Windows XP pops up the logon screen box, some of the
services might not yet be loaded. Thats why waiting seems to always work.

It typically happens to users the first boot up of the day, after the
computer has been off for some time, if you do a warm reboot or log off
then back on it seems to not happen. Any one else experienced this?
