Programs That Lock 0 Bytes at Byte 0 Lock Entire File (161838)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q161838 SYMPTOMS
The client program opens a file on the server and locks 0 bytes at position
(0). After this "lock_0_bytes_at_position_0," the same client cannot lock
any other byte_range of that file (lock_i_bytes_at position_j, with i>0,
j>0).
CAUSE
The locking mechanism incorrectly calculated the lock to be the entire
file, instead of 0.
RESOLUTION
Run a different application that can lock a byte range other than 0 bytes
at location byte 0 before running the application that will lock 0 bytes at
byte 0. This will then cause the 0 byte locking application to function
correctly.
-or-
Apply the hotfix for Windows NT 4.0.
STATUS
