Ten users at your office run an accounting application on their Windows NT Workstation 4.0 computers. The application stores its data in a shared network folder named Accdata on a Windows 2000 Server computer named Server1. You upgrade all 10 computers to Windows 2000 Professional and verify that all applications are compatible with Windows 2000. After the upgrade, some users report that they are receiving intermittent data-corruption error messages. They are also receiving data file-version mismatch error messages. When these errors occur, your only method of recovery is to restore the entire contents of the Accdata folder from a known good backup copy. You need to prevent these errors from occurring in the future. What should you do? （）

A. Configure Accdata folder to allow a maximum of one user.
B. Configure the Accdata folder to disable client caching.
Create a group policy that removes the Bypass Traverse Checking user right on server1.
D. Create a group policy that increases the amount of idle time required before a session disconnects on server1.
