Well, your problem is probably not the
same.
If the patch submitted under the same
subject doesn't help you, read on.

I suffered from the same problem a lot.
It appears to be this:

--------D-216C00-----------------------------
INT 21 - DOS 4.0+ - EXTENDED OPEN/CREATE
	AX = 6C00h
	BL = open mode as in AL for normal open (see also AH=3Dh)
[]

BUG:	this function has bugs (at least in DOS 5.0 and 6.2) 
when used with
drives handled via the network redirector (INT 2F/AX=112Eh):
- CX (attribute) is not passed to the redirector if DL=11h,
- CX does not return the status, it is returned unchanged 
because
DOS does a PUSH CX/POP CX when calling the redirector.

In case you suffer this BUG (applies also to a
PC-DOS), then the only solution would be to
switch to FreeDOS.
This bug plagued all the DosNavigator users
to death when they tried it under dosemu.
