Step 1
Start the server in Directory Services Restore Mode
Windows Server 2003/2008 Directory Service opens its files in exclusive mode. This means that the files cannot be managed while the server is operating as a domain controller. To perform any files movement related activities using ntdsutil, we need to start the server in Directory Services Restore Mode.
To start the server in Directory Services Restore mode, follow these steps:
Restart the computer.
After the BIOS information is displayed, press F8.
Use the DOWN ARROW to select Directory Services Restore Mode, and then press ENTER.
Log on with your local administrative account and password. (Not Domain Administrative account)
Note: using service control (SC.exe) you can verify quickly ntds services are running or stopped. In command prompt type SC query ntds
Step 2
How to Move Active Directory Database and Logs
You can move the Ntds.dit data file to a new folder. If you do so, the registry is updated so that Directory Service uses the new location when you restart the server.
To move the data file to another folder, follow these steps:
Click Start, click Run, type ntdsutil in the Open box, and then press ENTER.
At the Ntdsutil command prompt, type activate instance ntds, and then press ENTER.
At the Ntdsutil command prompt, type files, and then press ENTER.
At the file maintenance command prompt, type move DB to <new location> (where new location is an existing folder that you have created for this purpose) and then press ENTER.
In this case, the new location for database is C:\AD\Database
Now to move logs , at the file maintenance command prompt, type move logs to <new location> (where new location is an existing folder that you have created for this purpose) and then press ENTER. In our case, the new location for database is C:\AD\Logs
To quit file maintenance, type quit. Again to Ntdsutil, type quit to close the prompt
Restart the computer. AD database and Logs are moved successfully to new location.

Replmon had the option to generate a status report text file. It could tell you which servers were configured to replicate with each other, if they had any errors, and so on. It was pretty useful actually, and one of the main reasons people liked the tool.
Repadmin.exe offers similar functionality within a few of its command line options. For example, we can get a summary report:
Repadmin /replsummary *
Several DCs have been taken offline. Repadmin shows the correct error of 58 – that the other DCs are not available and cannot tell you their status.
You can also use more verbose commands with Repadmin to see details about which DCs are or are not replicating:
Repadmin /showrepl *

The easiest tool to use to verify that both the GPC and GPT have replicated is GPOTool. This tool is free and very easy to use. It comes with the operating system and can be run from a command prompt. Just type gpotool <dcname> /verbose from the command prompt, like you see in Figure 7.
dfsrdiag ReplicationState /member:CONTOSO-BRANCH

Performing Offline Defragmentation of Ntds.dit
These steps assume that you will be compacting the Ntds.dit file to a local folder. If you plan to defragment and compact the database to a remote shared folder, map a drive letter to that shared folder before you begin these steps, and use that drive letter in the path where appropriate.
1. Open an elevated command prompt. Click Start, and then right-click Command Prompt. Click Run as Administrator.
2. Type ntdsutil, and then press Enter.
3. Type Activate instance NTDS, and press Enter.
4. At the resulting ntdsutil prompt, type Files (case sensitive) and then press Enter.
5. At the file maintenance prompt, type compact to followed by the path to the destination folder for the defragmentation, and then press Enter.
