Hello everyone,
Today I need some help to solve a strange problem. In our company we recognized issues with files.
User A opens a file (excell sheet) and after that User B tries to open the same file. And it works! But it shouldn't.
I already enabled the security option in MS Office (Excel) to protect a file against multiple access.
So that cannot be the problem.
After some research I figured out, that this issue occurs more often when opening a file in the morning and keep it opened all the time until evening or 'til the middle of the day.
Is there a default timeout for keeping file_handles / lock states?
Is it possible to change this timeout?
Generally, why is it possible to access a file by multiple Users when oplocks are enabled and office settings deny multiple access?
Thx 4 any answer.
