Hi All,
We've just completed a disaster recovery test, and it caused a bunch of problems with Production servers and the domain. Can anyone help me with this?

We are replicating our servers to our DR site. The procedure is to bring the recovered box up in isolation (without network connectivity), change the name, IP address and put it into a workgroup. Then bring it live on the network and add the "new" server to the domain.

The problem is that a couple of days after doing this, some of our production servers removed themselves from the domain.

So either the isolated, replicated server saved the request to be removed from the domain until it could contact the DC?
OR the SSID of the server remains the same and removes the old computer account when the new computer account is created?

Anyone have any suggestions??
Thanks in Advance,
Gary

One final step, you will want to Sysprep the systems, although many applications will not take kindly to being renamed, especially Exchange. SQL will require some work as well.

Why do you add the DR servers to the "Live" domain? Can you not just test in the recovery environment, disconnected from the "live" network?

There are many solutions out there that let you do automated DR testing in a virtual environment, including the XenServer and Hyper-V solutions from my company, SteelEye Technology.

Hi David,

Thanks for the reply. One of the good/bad things about our setup is that a lot of our services are hosted elsewhere around the world. So on one hand, some applications and services are someone else's problem, but on the other hand we need the DR servers back on the live network to test connections to the remote shared services.

Thanks for the input and the links though!

Cheers,
Gary
