Few days back i faced hardware issue with one of my DC in my AD environment (Windows server 2008 R2), and the only option with me was to make that server on new hardware with same name and IP.
So i start for cleaning the meta data of old DC as per recommendation of Microsoft.
After cleaning the meta Data of that old DC i check replication through the following command and got the error "(1753) There are no more end points available from the endpoint mapper"

After that i check replication as mentioned below.

Then i started building the new server with the following steps.
- Install same OS version on new hardware
- Assign the same Name
- Assign the same IP
- Joined to the domain
- Start/Run DCpromo on it
After that i check replication as mentioned below.
