My problem with the USE "Z:" seems to be remedied, but now my Win98 clients won't map to (USE X: "\\server00\@userid" + $)see under.
I'm thinking, could it be a problem that it's the last drive beening used (eg first a problem with Z then with X). I will try a dummy mapping to "z" and get back to you.
If anyone has a suggestion in the meantime, please advise.

IF INGROUP ("HOMELESS")=1
$Drive = "X:"
$Share = "\Home" ; Home dirs
$SrvList = "00"
GOSUB "Connect"
ELSE
USE X: "\\server00\@userid" + $
ENDIF
