Hi Guys,

In Windows 2000 how to defragment SYSVOL on domain
controller.

My SYSVOL has bloated to 5.6 Gb. Require your assistance
for the same.

As a general rule, defragmentation doesn't really free up space but rather
reorganises things in a more logical order. Having said that, you can
perform an offline defragmentation of ntds.dit which might free up some
space http://support.microsoft.com/?id=232122

What is taking up all the space in Sysvol? Do you have any folders that
include _NTFRS in the folder name?
 
Hi Simon,

Thanks for ur reply. I have thoroughly checked the SYSVOL.
It does contain 120 folders with the _NTFRS name.

Pls. advise. Secondly why does those folders get created.

Regards..Tiju
 
These _NTFRS folders are called morphed directories and they indicate an FRS
problem. eg they can be created if there is a collision in FRS when the same
object is created simultaneously in two places.

It will most likely be these folders taking up all the space, this KB will
tell you how to remove them safely. You basically have to find which folder
contains the good copy of your data (the morph folder or the 'real' folder)
and then delete the other one.

It may also be required to perform a non-authoritative restore of FRS with
the burflags registry key to reinitialise FRS.

Things to check before you do anything:
Make a one off copy of Sysvol, just copy the folder to another location and
make that your backup.
Do a full System State backup
Check the System log for JOURNAL_WRAP errors. If these are present you need
to D2 the server with the burflags key.

Install SP4 on all your DC's. There are a lot of FRS hotfixes and changes in
SP3 and SP4.
 
That is incorrect. On-Line defrag does NOT clear out spaces in the database.
An Off-Line defrag does. This frees up space. This is why MS recommends
doing it on a regular basis to reduce the size of AD so you have improved
performance. I have seen it reduce the size as much as 50%
