I use Microsoft Access MDB file to store program configurations for my tools. Recently some users told me some of my tools start up abnormal because configuration data could not read from the MDB file. I installed a testing Windows 2003 R2 server and applied the latest patches, found that the problem can be easily simulated. I recreated such MDB file from a workable one and the problem was gone immediately, it seemed something wrong that I could not explain. I recreated the relevant MDB file for my tools and updated the file in SourceForge, please download the file if you also encountered this problem.
