Hello

Regarding a server that fulfills the Active Directory / DNS role.

What would be the best way to replicate the users and DNS zones?

Should I purchase a disaster recovery solution to include it in a replica from main site to contingency site?

Or can I create a second DNS server at my contingency site and replicate the zones and records from the primary DNS to the secondary DNS?

which is the most recommended way for these cases.

    Hi

    You can promote another ADDS/DNS server, and the record will be sync'ed between the two.

    You could use it on another site if you want to protect against a fire in exemple.

    I would recommand too to use the Windows Backup's role to do a full backup of your server, as another server serve in case of a crash, but if a event occur and you need to restore you need a backup plan of your AD too.

    Thanks

    Hello there,

    Adding the assigned IP, after configuring the Teaming, it continues with the same Multiple IP Addressess message.

    Performing an ipconfig / all, it indicates that the ip is duplicated, I show the results:

    134103-before-setting-up-nic-teaming.png134093-after-setting-up-nic-teaming.png134104-ipconfig.png

    Indicates that the ip is duplicated, perhaps assigned to another service on a different server.

    However I would like to see if there is something else that may be causing this message.
