what Prequations want to take before formate the server with Active Directory and DNS insstalled

Hai.

We are using normal server not SMB server.

1) Can u explain some what clearly.
2) Or else give me any suggested links

Thanks

Okay good, SBS changes things significantly. One more question on this, the new server, which OS are you installing on it? 2003? 2008? 2008 R2?

In general, the process for your upgrade is this:

1. Install the base operating system on the new server, setting name and IP address as usual
2. Join the server to the existing domain (in the same way as you would join a desktop system)
3. Run DCPromo on the new server, adding it as an Additional Domain Controller to the Existing Domain
4. Wait until promotion completes
5. Install the DNS Service (AD Integrated Zones will automatically appear after a short period, do not create any zones at this stage)
6. In AD Sites and Services, drill down to your new server. Right click on the "NTDS Settings" entry beneath the server and select Properties. Tick "Global Catalog".

That completes the server build. You will have two Domain Controllers looking after the same domain at this stage. Maintaining two is better than one, had you planned to decommission the older server?

Do you use DHCP on the existing server? Do you want to move that?

Does the existing server do anything else? MS Exchange, for example?

These 2 articles explains with details everything you need for different scenarios, including the one you want.

If you just want a safe and quick how-to take a look at this article (not for Small Business 2003 Server):

Hai Thanks for your valualbe explanation

1) Yes in my previous server have Dhcp and Ms exchange.
2) And one more thing, i heard some ware that if we format the server we should do some work with FSMO rules.
3) That FSMO rules are necessary for do that.

Thanks

1. Exchange complicates things significantly.

You cannot demote this server while Exchange sits there. You must be in a position to uninstall Exchange from that server first.

Which version of Exchange? Are you planning to install Exchange on the new server?

2 and 3 should not be considered until the situation with Exchange is resolved.

Chris

No, we are planing to remove the exchange server and use Linux mechine.

So, it is not important to take ms-exchange backup.

So, we concentrate on only Active directory database and Dns database.
