As per Microsoft: "This issue can occur if the FRS Jet database or one of its logs has been corrupted.". The ME264607
detailing the problem has been removed from Microsoft's site. This probably means that the information was not really accurate. Here is a summary of the article:
"Microsoft Knowledge Base Article ME264607
- Event ID 13507, 13552, and 13555 Messages Occur in the Domain Controller
In a Microsoft Windows 2000 domain controller with Microsoft Terminal Services installed in application server mode, errors may be displayed in the System event log. Cause: When you install Citrix MetaFrame Server version 1.8 on a Windows 2000 domain controller, you are prompted to re-map the server's drive letters (C-M), so that clients do not confuse their drive C with the server's drive C. When the drive is remapped, File Replication service (FRS) does not work correctly; FRS looks for drive letters that no longer exist. (updated 8/31/2000)".
The suggested solution:
1. Install another computer with Windows 2000 Server, and promote it as a domain controller.
2. Use "Dcpromo.exe", in order to downgrade the domain controller on which Citrix MetaFrame was installed, to a member server of the domain.
3. Use "Dcpromo.exe", in order to upgrade the member server again to a domain controller. In this way, the system files are rebuilt.
4. Stop NetLogon and the replication on the new domain controller.
5. Delete the file "Ntfrs.jdb" from the <windir>\Ntfrs\Jet directory.
6. Delete the file "Edb.txt" from the file <windir>\Ntfrs\Jet\Sys
7. Delete the file "Edb.txt", from the file "Res1.txt" and the file "Res2.txt" from the <windir>\Ntfrs\Jet\Log directory.
8. Restart the domain controller.
