Does @WUSERID return a value for those Win95 clients which don't return @USERID?

code:
If @USERID $USERID=@USERID Else $USERID=@WUSERID EndIf

$HomeShr = "H:"
$Ser1 = "\\Server1"

use $HomeShr $Ser1+"\"+$USERID+"$$"
If @ERROR
   "FATAL: Failed to map drive to "+$Ser1+"\"+$USERID+"$$"+@CRLF
   "       Error: "+@ERROR+" "+@SERROR+@CRLF
EndIf
