Microsoft Jet Database Engine error '123' Solution

I re-installed the operating system today. To learn about Asp.net, I changed the system disk to the NTFS format. The ASP files I usually use for debugging are stored on the d disk (partitions in FAT32 format ), previously able to debug normallyProgramNow, once the database is connected, an error occurs. Even if ODBC is used, the connection fails. If jet is used, the error '000000' is reported. I went to Baidu to check some information, I suddenly thought about the security between NTFs and FAT32, for example, write permission. I know that access to the NTFS drive letter by the FAT32 operating system will fail, but now the opposite is true.
I can't give up after thinking a little bit. I opened the IIS manager and right-click my server to select permissions, prompting me to store the files to be accessed on the FAT32 drive letter, which does not guarantee security, in this case, I found the root cause of the problem. The user accessing IIS does not have the permission to access the FAT32 disk. Therefore, on the Directory Security tab, I found the user iusr_a0f4685a93e2479 accessing IIS, since this user has insufficient permissions, the permission group must have low permissions. Therefore, I right-click my computer and choose manage to find the local user and the user name in the group, re-assign the Administrator group to him, and refresh the browser. No, no. Try restarting the following IIS. The result is OK. You still need to restart IIS, haha.
