Microsoft Network type

Most of our servers are Windows server 2008 with our DNS server and FSMO being on a Windows 2008 Server.
However, we saw a setting in Active Directory that indicated our network is considered a "Windows 2003" network. We cannot find this listing again.

Where can we find what type our network is and how can we update this to 2008?

Any assistance offered would be appreciated.

Open properties of active directory  domains and trust you have listed and it will tell you domain functional level and forest functional level

Okay. That was it. The Domain function level is at Windows Server 2003 and the Forest function level is Windows 2000. Is there a link for how these can be raised and the consequences of doing so?

1. Run DSA.MSC and right click on you domain name then click on "Raise domain Functional Level"

2. Run DOMAIN.MSC and right click on you domain name then click on "Raise forest Functional Level"

Note: Raising the functional level is not revertable.

Okay, so if the Forest functional level is Windows 2000 and we don't have one single Windows 2000 server inhouse then it should be okay? What exactly is the benefit of raising the Forest functional level?

Hi,

1. Raising the functional level will always enable the more function to your domain.

2. if you dont have any windows 2003 and windows 2000 OS running as domain controller then you can raise your functional level to windows 2008 .

3. And even you dont have  "windows 2008" OS then you can use FFL & DFL to windows 2008 R2.

We do have some domain controllers that are windows 2003 but we do not have any windows servers that are windows 2000 os and the function level is currently Windows 2000. It is prompting to go to Windows 2003

yes please, if you have the windows 2003 server and running as domain controllers then pls go to "windows 2003 FFL and DFL" only.

We have four domain controllers. Two are 2003 and two are 2008. Where are the FFL and DFL only?

Okay, thank you. And we are currently running a back of the domain settings but the scenario we posted should be okay?

":)

FFL-forest Functional Level
DFL-domain Functional Level

 1. Run DSA.MSC and right click on you domain name then click on "Raise domain Functional Level"

2. Run DOMAIN.MSC and right click on you domain name then click on "Raise forest Functional Level"

We can only raise the forest function level as we have windows 2003 and windows 2008 domain controllers. Will this hurt us if we only raise the forest functional level from windows 2000 to windows 2003?

Again, you dont have any windows 2000 server that is running as Domain controller in forest, then you can raise the both FFL and DFL.

its very safe. To know more about  raising the Functional level see the url.. http://technet.microsoft.com/library/understanding-active-directory-functional-levels%28v=WS.10%29.aspx

"Again, you dont have any windows 2000 server that is running as Domain controller in forest, then you can raise the both FFL and DFL."

We can't do the domain function level. We are getting the message: "Current domain functional level: Windows Server 2003. This domain is operating at the highest possible functional level."
