Well in my testing using any of the Map UDF (without shelling to NET USE) was unable to remove the drive mapping.

I still say that there are situations where KiXtart can not remove the drive mapping, but NET USE can. So to me I think KiX needs to be reviewed by Ruud to determine what is being done differently in NET USE then his code.

i.e. Maybe KiX needs a FORCE switch or something.
