Old MUP bug: 5 IRP stack locations

Several years ago, I’ve reported this on W2003. At the time, it
seemed solved, but it resurfaced again. This is the original report:

On XP/2003 machines that connect to a DFS share (not regular
shares), MUP will allocate a maximum of 5 IRP stack locations. Using one
for itself, this leaves space for 3 filters. Putting 4 legacy filters on
the system causes a IRP_NO_MORE_STACK_LOCATIONS.
Increasing DfsIrpStackSize under Mup\Parameters doesn’t affect
anything (it’s 10 anyway by default).

Tony, do you remember if you did anything regarding the dump I have
mailed back then?:slight_smile:
