| Description | %1 (%2) %3An attempt to open the file "%4" for read only access failed with system error %6: "%7". The open file operation will fail with error %5. |
| Event Information | According to Microsoft: EXPLANATION: An error occurred while a file was being opened. Probable causes include: 1. The file is locked or in use. 2. A virus checker might have mistakenly quarantined a file, or a backup process might have temporarily denied access. 3. A flat file backup system or anti-virus software might be running against the database, the check file directories, or the M drive. 4. The permissions on the folder (such as MDBDATA) that contains the files for the information stores are not sufficient for the stores to function correctly. 5. A disk input/output (I/O) problem prevented access to a requested page in the database or to a check file. A disk or controller failure may have occurred, and access to the entire drive was lost, perhaps temporarily. This issue can occur when the path for the check file (such as E00.chk) is not correct. 6. The path for the log files or the check file was changed before the system was restored. 6. The check file (such as E00.chk) is corrupted. |
