[K12OSN] Help!! All clients fail to log onto desktop

["Jim Christiansen" <christiansen_j hotmail com>]

Help!  I got to work this morning to find 30 students milling around the 
library computer all asking me to fix the server...

All of the terminals will boot up to our logon screen.  The boxes accept 
logons and progress to the plain icewm background- but no taskbar.

I had a student helper start a DMCP Chooser from a linux standalone in my 
room to logonto the library server...   Everythning is fine...  Full 
desktop.

I haven't made any recent changes to this server.

Please, any ideas are welcomed.

Jim
