This option is not visible by default

You first need to uncheck the box before "use simple file sharing" under the tool-folder option.

Then when you right-click the partition drive letter and folders and files, select Properties and see the Security option in its options.

The immediate output err.Number shows-2147467259, while err.De ion shows an "unknown error".

Problem analysis:

The above error actually occurred because the MS Jet engine did not have write permission to the temporary directory "C:\ Windows\ Temp", causing the database creation to fail.

My solution is as follows:

1. Set IIS anonymous users, assuming that it is now set to ISUER_ studyer

2. Add full control permissions for ISUER_ studyer on the folder C:\ Windows\ Temp (temporary directory). Specific actions: right-click the Temp folder, select "Properties"-> "Security"-> "Edit"-> "add"-> add the user "ISUER_ studyer", and give full control.

3. OK, troubleshooting.
