Hiarcs uses "Volume Serial Number" (VSN) of the hard disk volume where it was installed to encrypt several files in a hidden directory (which it puts inside hiarcs6 directory). When you run it, it gets the volume serial number (a 32 bit number from MS-DOS call int 21h, ax=440D, subf. 66h), decrypts the files and is happy until you unload it. So to install it on your NT Server, you would install it on a DOS machine, then copy manually the hidden directory (and its hidden subdirectories) to the NT volume, and install a small TSR (in asm it would take a hundred bytes at most) which will fake the MS-DOS Get VSN call (440D,66; which NT ignores on non FAT drives) and return the same VSN as the DOS drive had.
