Vaxstation 4000/60 DECwindows

Hello list - I have a Vaxstation 4000/60 running VMS 7.3. DW-MOTIF is installed, TAILOR=on, License OK... @SYS$TEST:DECW$IVP say: Copyright Compaq Computer Corporation 1988, 2000. DECwindows Motif for OpenVMS Installation Verification Procedure (IVP) This IVP is intended to test some of the functionality of DECwindows Motif for OpenVMS and to provide a quick method of verifying the installation. This machine is not a workstation. Please provide the nodename of a workstation on which to display the IVP tests. You must be sure that this account and node have security access to the display node, or the IVP will fail. To skip the display-oriented tests, press Ctrl/Z at the following prompt. Why IVP detect the Vaxstation as not a workstation? Serial Console is off... Any ideas?
