Hi, Thank you for your post. According to your description, I understand that you encountered some error message in event view. If I am off base please let me know. Based on my research, it appears that we need to perform an offline defragmentation. Use the following procedures to perform offline defragmentation. Procedures are explained in detail in the following articles: Active Directory Operations Guide Appendix A - Tasks Reference http://www.microsoft.com/technet/prodtechnol/windows2000serv/technologies/ac tivedirectory/maintain/opsguide/part2/adogdapa.mspx#EUAA Appendix B - Procedures Reference http://www.microsoft.com/technet/prodtechnol/windows2000serv/technologies/ac tivedirectory/maintain/opsguide/part2/adogdapb.mspx#E0CE0AA 1. Back up system state. System state includes the database file and database log files as well as SYSVOL, NETLOGON, and the registry, among other things. Always ensure that a current backup exists prior to defragmenting database files. 2. Take the domain controller offline, as follows: If you are logged on to the domain controller locally, restart the domain controller in Directory Services Restore Mode. If you are using Terminal Services for remote administration, you can remotely restart the domain controller in Directory Services Restore Mode after modifying the Boot.ini file on the remote server. 3. Compact the directory database file (offline defragmentation). As part of the offline defragmentation procedure, check directory database integrity. 4. If database integrity check fails, perform semantic database analysis with fixup. Hope the above information helps, if you have any further issue, please let me know. I am standing by to be of further assistance.
