Change Hostname of Backup domain controller

Hello Experts,

I have a network with one Domain controller with Windows 2008 R2 Standard 64BIT. Before some days back, i got one issue within the GPO in my Domain controller. So my seniors asked me to create one additional domain controller. So i have created one simple server with same OS configuration as per the primary DC. But i forgot to change the Hostname as windows server 2008 media will automatically assigned random hostnames. Now i have installed and configured this server as my Additional domain controller. And now i got to know that i have to change this weird name.

Can u please suggest any issues will come if i change this?

Please help.

Why would you demote the DC, it doesn't matter if it's a BDC or DC, the renaming process stays the same.

You can rename the Domain Controller without too much problems.

1) Rename Domain Controller (via System properties or netdom)
2) Update the FRS or DFS Replication Member Object.

That should be it ... The only issue that could happen is that AD and DNS replication slowness might for while prevent clients locating or authenticating to the renamed DC ... As you would expect.
