SUMMARY
Do not put files that are managed by extensible storage engine (ESENT or ESE) on a compressed drive. Placing a Microsoft Jet database on a compressed drive may cause write-through delays that can cause Jet database corruption.



MORE INFORMATION
To avoid a possible data loss that may be caused by a corrupted database, make sure not to put the following items on a compressed drive. Note that this list includes any Jet-related files such as DIT files, logs, checkpoints, and temporary databases:
 * Active Directory (NTDS)
 * File Replication service (FRS)
 * Windows Internet Name service (WINS)
 * DHCP
 * Security Configuration Engine (SCE)
 * Certificate Server
 * Terminal Services Session folder
 * Terminal Services Licensing service
 * Catalog database
 * Help and Support Services
 * Directory Synchronization service (MSDSS)
 * Remote Storage (RSS)
 * Phone Book service
 * Single Instance Store (SIS) Groveler
 * Windows NT Backup/Restore
 * Exchange store
 * Microsoft Exchange folder (SRS and DXA)
 * Key Management service (KMS)
 * Instant Messaging
 * Content Indexing

Note Do not install Windows Server 2003, Standard Edition, on a compressed drive unless the drive was compressed with the NTFS file system compression utility. Uncompress a DriveSpace or DoubleSpace volume before running Setup on it.
