Any issues running a 2003 R2 64 bit DC alongside 2003 R2 32 bit DC's

We are running a 2003/2003 forest and domain function level environment. Currently all of our domain controllers are server 2003 R2 32 bit.

We have a very small office that will only have a DC present. Normally we would use a 32 bit OS for this but this server will also need to be a print server sharing 64 bit drivers.

Are there any issues with adding a 64 bit DC to environment? Any additional steps I need to be aware of or look out for?

Thanks

Hi, there should be no issues.  It won't affect AD.

You will need to prep your domain/forest for 2008 R2.  You will be using adprep32 for that since your current DCs are 32 bit.



Thanks

Mike He will be using 2003 R2 not 2008 so what I think that he won't need to use adprep32
He can add new DC with no additional efforts and issues

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

 
Mike KlineCommented:
good point, yeah use adprep, in your case use it from disk 2 on the R2 set....have you thought about going to 2008 R2?

That is something we are looking to do in the future but currently some of our other systems dont support it yet. Mostly our older Cisco phone system.

Just to be clear, no adprep is needed at all, since your current DC is already running 2003 R2.  The 32- and 64-bit versions are the same as far as AD is concerned.

xxdcmast :-No additional activity needed Just add as if you are adding a DC with same OS version

No need of adprep or adprep32 those would be needed if you r putting a 2008 DC in Domain
