Hello All,

We have currently a forest as A.com and we are using Windows 2008 R2 Sp1 in that

We have 350 user accounts in that.

We are planing to introduce a new domain or Forest as B.com with Windows 2012 R2

This new domain should be able to handle 1000 user accounts.

kindly suggest me with hardware requirements for Domain controller 

Also How many domain controllers we need

Thanks,

Sam

Though this is not the correct forum for your question

Ideally I would recommend 2 DC for any Domain AT LEAST

Second for the DC hardware

More RAM:

The more memory available for caching the better. It's really that simple.

Disks:

Put the AD Database (ntds.dit) onto separate disk spindles (ideally RAID protected and as fast as possible).

Allow at least 0.5Gb per 1000 users when allocating disk space for the AD database. Given the price of RAM these days, this probably isn't a bad idea for growing the RAM allocation either.

Network connections:

Faster network will always help response but you will only see a return on money spent here if no other parts of the system are acting as a bottleneck.

Processor:

Multiple cores are king; these days its probably better to have (and probably easier to purchase!) more processor cores than fewer, but faster single cores. I'd say that anything more than dual core might be difficult to justify on a DC without testing, however, but you'd probably want to go quad core if you were planning to have more than 10,000 users.

Other Server Roles:

Be careful about how you mix server roles.

There are certain roles that typically get folded in with the domain controller in all but the biggest networks (e.g. DNS/DHCP/WINS/Cert Server) with little harm.

Hello Edwin,

Thanks for the detailed information

Thanks,
