Thanks for your suggestions, Dave. I was beginning to go down the lines
you suggest when I found out two other pieces of the puzzle: (1) It
*might* be affecting all users. I have now determined that more users
than I first thought are experiencing the problem, and (2) of those
users who have reported the problem, it seems that the issue might be
happening the first time (in a day) they attempt to access a particular
folder on the server. All users access a share on the server via a
mapped drive (connected through a common login script), and the folder
in question is a subfolder of that share. I don't at this time know how
reliable the user reports are of this (I hope to verify details after
the weekend), but for now I have re-created the folder tree in question
and will see what effect this has. I have also found all sorts of
shortcuts in the share that individual users have created to other
folders and documents in the shared folder tree, some of which are
valid and some not. I have deleted these to narrow down possible
causes, and will have to educate them to keep personal shortcuts just
that: personal (and in their own My Docs folders).
Other than that there is no WiFi on their LAN, and I have verified the
ipconfigs of affected workstations: indeed, I have spent considerable
effort of late to harmonise all workstation configurations and
troubleshoot DHCP, DNS, group policies, profiles and folder
redirection, etc. This network was in a complete mess when I inherited
it, having been set up and managed by so-called IT experts who hadn't a
clue what they were doing and no knowledge of SBS at all. Apart from
this knotty issue, everything appears absolutely fine now, though, and
set up the way an SBS network should be.
