Read Only Domain Controller issue

Hi,
    Im having a domain named abc.com with a sinlge RWDC1 and then i had promoted RODC in another server. After promoting RODC. In Active Directory user and computer console defaultly i can able to create users and delete users because its console is not RODC console its RWDC1 console . How its is possible. After i changed to the RODC console its not possible to create or delete users. So in RODC their are telling unidirectional replication. If i use RWDC1 Active directory Console in RODC its possible to create users and delete. How its possible it is  unidirectional. Why after installing RODC its shows RWDC1 Active directory users and computers console instead of RODC Active directory users and console. Please dont give reference links.

I think I understand what you are saying.

Can you confirm which Domain Controller the snapin is connected to? Right click atvthe top if the tree and chose select domain controller.

After promoting RODC . Its connected to RWDC console only also its possible to change to RODC console. My doubt is that. If RWDC Active directory users and computers console available in RODC means its possible to create users and delete users. So there is no secutiry. its my doubt
Glen KnightCommented:
The RODC is mainly for use in an area with lack of physical security.  It will not stop the ability to create or delete users because the console will simply connect to a writeable DC.

No. After connecting to Writable DC Console in RODC.iits possible to create and delete users . How its possible.
Glen KnightCommented:
Because the writeable console will connect to the writeable DC.  Check and you will see.

Yes its connecting to writable DC only. Thats not my doubt . My doubt is if i connect to RWDC console in RODC means its possible to create users and delete users . After promoting RODC first it shows RWDC Active directory users and computers Console instead of  RODC Active directory users and computers console.. Whether its the default console for RODC or i had did any mistake.
Glen KnightCommented:
What you are seeing is correct.
columbusengAuthor Commented:
Fine. Is it possible to block change console option in active directory users and computers by using Group policy to prevent accessing RWDC Console.
Glen KnightCommented:
I don't think so.  It's a snapin for the MMC console.  You can blickbthe MMC console but that will block everything that uses the MMC console.

If you are able to make changes on RODC, its not a writable DC as data can't be written on RODC,because of unidirectional replication mechanism.
