Hi Guys,
Good Day! I've read a the procedures in upgrading a Domain Controller
however, there are things that I need to know more before I proceed just to make
sure of everything:- The 1st Domain Controller (Server 2003 x86) running the Active Directory, DNS and DHCP.
QUESTION: What happens if I did not continue the upgrade but already run the adprep?
QUESTION: After the upgrade, will the AD, DNS and DHCP remain un-touched?
- The 2nd Domain Controller (Server 2003 x86) running Active Directory and DNS only.
QUESTION: Is the procedure the same (running adprep)?
- I have a Member Server (Server 2003 x86) that is a file server and SQL 2005 server at the same time.
QUESTION1: Is the procedure the same (running adprep)?
QUESTION2: Will the Security/Permission Settings in all the folders and SQL Database remain untouched after the upgrade?
- We already have a few member servers that is running Server 2008 x86 on the network.
QUESTION: Will this be affected after the upgrade?
Appreciate your advise. Thanks

Hello,
adprep commands are used ONCE in the domain and not on each server. Important is that ALL DCs are up and running when adprep is used.
Domain member servers are NOT effected from adprep commands, this belongs to the DCs.
Security permissions in the domain are NOT effected from upgrade of the DCs OS.
There is no problem running Windows server 2003/2008/2008 R2 together as DCs or domain member servers in the domain, they work without any problem together.
If SQL 2005 is supported with Windows server 2008 and how to upgrade/migrate please check with SQL experts in http://social.technet.microsoft.com/Forums/en-US/category/sqlserver/
For the DC change to new OS i suggest to do fresh installs and NOT to work with in-place upgrades, even if they are full supported from Microsoft, IF the architecture is the same, so 32bit can NOT be in-place upgraded to 64bit.
See here about details how to upgrade http://msmvps.com/blogs/mweber/archive/2010/02/10/upgrading-an-active-directory-domain-from-windows-server-2003-to-windows-server-2008-or-windows-server-2008-r2.aspx

Hi,
1. It is fine only adprep runs but no upgrade. Adprep command is used to extend schema.
2.
--> ADPREP /Forestprep on the w2k/w2k3 schema master (both w2k/w2k3 forests)
--> ADPREP /rodcprep on the w2k3 domain master (only w2k3 forests)
--> ADPREP /domainprep on the w2k3 infrastructure master (only w2k3 domains)
--> ADPREP /domainprep /gpprep on the w2k infrastructure master (only w2k domains)
3. It should be fine if you don't touch anything that related with SQL Server, but I would like also suggest you post a thread in the SQL Server forum.
4. After you upgrade your domain to Windows 2008, more features in Group Policy and so on.
Please also go through the below two similar threads regarding to upgrading Windows Server 2003:
2003 server to Server 2008
How to upgrade a Windows 2003 R2 domain to Windows 2008 R2?

Hi Guys,
Many thanks for your reply. Just a quick one with regards to this upgrade.
My Domain Controller OS is sitting on a RAID 1 DISK (MIRROR)
Q1: Is there any effect on RAID 1 during the upgrade process?
Q2: If yes what is the best way to achieve the upgrade without a problem?
ThanksAC
