Microsoft Access database intermittenly reports that the database file is "Read Only" on opening. Ths issue seems to occur randomly even when the user is an administrator, and the administrator is the only user with the file open. The database is used by about 20 users. The error is not a locked file error, it's a read only error. Checking the attributes in the properties window of the file does not indicate that the file is read only. It usually happens around 3-4pm in the afternoon, 3 times a week. Will post the error code when I see it again.
