See the paste below, it's getting worse, restarting the wm doesn't help
anymore, now i've got to restart the server to get it functioning again.
Is there a way to give the wm a good kick, so i don't have to restart the
whole server? i tried restarting all the zen services, run zwsreg
unreg/reg but it just won't pick up the missing policies...

paste from wrong forum:
Ive got a setup with w2003 and citrix presentationserver 4. I use zen7 to
manage the application distibution, policies, schedules and startmenu. It
all works fine, but the workstation manager seems to lose its connection,
which is visible in de wmsched.exe, where the serverpolicies disappear &
newly created/updated workstation apps don't distribute.
When i restart de wm, it all works again for a little while. i inserted a
local 'wm restart' schedule, but this shouldn't be necessary...
First i thought it could have something to do with dual/teamed network
cards, but on a testserver, which only got one adapter enabled, the wm
also loses it's info.
