Ultrasound has detected that changes are being made to the
volume faster than FRS can detect them in the USN journal and log
them in the FRS database. The recommended USN journal size is
128 MB per 100,000 files on the volume. If the USN journal is
too small for the number of files on the volume, including those
outside of the replica tree, a USN journal wrap error can occur,
which causes replication to cease and requires a nonauthoritative
restore to correct.
Default USN journal sizes are as follows:
Prior to Windows 2000 SP3, the default journal size is
32 MB and the maximum journal size is 128 MB.
In Windows 2000 SP3, the default journal size is
128 MB, and the maximum journal size is 10,000 MB.
In Windows 2000 SP3 with the post-Service Pack 3 release
of Ntfrs.exe, described in article 815473, and Windows 2000
SP4, the default journal size is 512 MB.
In Windows Server 2003, the default journal size is
128 MB. After you install the pre-Service Pack 1 release of
Ntfrs.exe as described in article 823230, the default journal size
is 512 MB.
You can increase the size of the USN journal by modifying the
registry, but keep in mind that after you increase it, you should
not lower it again because this will cause a USN journal wrap.
Increase the USN journal size to 128 MB per 100,000 files
on the volume.
In the Run dialog box, type regedit.exe, and
Right-click the Parameters subkey and choose New

Type NTFS journal size in MB as the new value name and

Click Decimal, and then in the Value data field,
type the size in megabytes that you would like to make the NTFS
Click OK, and then close the Registry Editor.
At the command prompt, type net stop ntfrs & net start
Do not edit the registry unless you have no alternative. The
registry editor bypasses standard safeguards, allowing settings
that can damage your system, or even require you to reinstall
Windows. If you must edit the registry, back it up first and see
