Heuristics Don't Disable MS-DOS Workstation Write-Behind (98417)
This article was previously published under Q98417
SUMMARY
There is no effective way to disable MS-DOS workstation write-behind
using heuristics.
- Heuristic 0 sets the write-through bit on write SMBs telling the
server not to return until the data is written, but does not disable
the redir write-behind.
- Heuristic 1 applies only to write&X when X is submitted by the user
application (as in CLOSE).
- Heuristic 4 does not, as documented, apply to writes: only to READs.
- Heuristic 10 applies only to FLUSH--COMMIT: not writes.
New heuristic (16) in LAN Manager 2.1a allows you to disable write-behind,
but only on files opened in compatible mode, not in deny-none mode.
