INT 2F - NETWORK REDIRECTOR - FINDNEXT

	AX = 111Ch
	SS = DS = DOS DS
	ES:DI -> CDS
	ES:DI -> DTA (MSDOS v5.0)
	[DTA] = 21-byte findfirst search data
	      (see #01626 at INT 21/AH=4Eh)
Return: CF set on error
	    AX = DOS error code (see #01680 at INT 21/AH=59h/BX=0000h)
	CF clear if successful
	    [DTA] = updated findfirst search data
		    (bit 7 of first byte must be set)
	    [DTA+15h] = standard directory entry for file (see #01352)
Note:	this function is called by the DOS 3.1+ kernel
