[Kolab-devel] [issue2689] Starting/Installing Kontact on initiates irritating DNS connections

[Bernhard Reiter]

New submission from Bernhard Reiter <bernhard at intevation.de>:

Tested Kontact-Installer_20080412.exe on Vista       
and it did a couple of DNS connections for that we should know the reasons.     
(They seem to be unnecessary.)     
     
Details     
     
At Install time:     
kbuildsycoca4.exe  DNS     
(probably our script running kbuildsycoca once).     
     
starting kontact:     
     
kolabwizard.exe DNS     
klauncher.exe DNS     
kdeinit4.exe DNS     
kded4.exe DNS     
knotify.exeDNS     
kbuildsycoca4.exe DNS     
kontact.exe DNS     
     
korgac.exe DNS

So it is probably windows. Till guesses dbus.
