OK, here is your problem.
I assume you are configuring the “Q” letter directly on the unit under Start-System Setup-Preferences, right?
In your wnos.ini you are saying to map all drives under letter “Z” (last line in your wnos.ini).
Both is not working.
Either remove the local or the wnos.ini parameter.
You can replace the last line by “SessionConfig=ICA DiskMapTo=Q ” to get the needed result.
Mapping disks under a special drive name will only work, if the disk is already attached when starting the ICA session. Otherwise you have to use “SessionConfig=ICA MapDisksUnderZ=yes”
