There are two LANRES programs provided by LANRES for disk serving. One is intended for use on NetWare Version 3 and is named EWXDISK3.DSK and the other is intended for use on NetWare Version 4 and is named EWXDISK4.DSK. Both programs are shipped on the LANRES diskette and the LANRES installation installs both into the SYS:\EWXNLM subdirectory. The installation program also determines what version of NetWare is running on the NetWare file server from which the LANRES installation program is being invoked and copies the LANRES disk serving program that is compatible with that version, to the SYS:\EWXNLM subdirectory as the program named EWXDISK.DSK. Invoking the LANRES installation program from a NetWare 3.xx file server, three programs, EWXDISK3.DSK, EWXDISK4.DSK and EWXDISK.DSK are installed to the SYS:\EWXNLM subdirectory and the EWXDISK.DSK program is a copy of the EWXDISK3.DSK program and must be loaded only on NetWare version 3.xx file servers. Invoking the LANRES installation program from a NetWare 4.xx file server, three programs, EWXDISK3.DSK, EWXDISK4.DSK and EWXDISK.DSK are installed to the SYS:\EWXNLM subdirectory and the EWXDISK.DSK program is a copy of the EWXDISK4.DSK program and must be loaded only on NetWare version 4.xx file servers. This error message indicates that EWXDISK.DSK is being executed on a NetWare file server that is running a different version from that which the LANRES installation program was invoked.
