Adding a second DC in 2003 server and replication

When I add another DC to my domain  Will the replica of AD include replication of IIS as we use this for our intranet. It is essential really that if the main server goes down the other DC will keep the Intranet running. All the files are stored on a NAS server so we wont lose access to them.

Just to clearify my first posting. That will not replicate the web site as Chris-Dent says but it will releive you from the problem of different ip since both servers will have the same virtual ip
You can create a NLB cluster that will do this. See the following link:

This course will introduce you to SQL Server Core 2016, as well as teach you about SSMS, data tools, installation, server configuration, using Management Studio, and writing and executing queries.

Hi TD,

AD replication will not include replication of the IIS Metabase - the two are completely seperate.

You can create a copy of the site on the second DC and have it access the same files, however you will find that the address used to access the site will also have to be different or the address will have to be manually changed in the event of the main server going down.


This is also an application from MS that will allow you to automatically replicate and give redundancy to web sites:

It might be easier to use something like the IIS Migration Tool to get a copy of the site setup on the second server. I forgot all about Network Load Balancing, but that seems like quite a good way to go with it.

The above link Is how microsoft says to configure a IIS Fail over system.  If it detects that the Primary IIS Server is down it updated DNS Records to point to your backup server.

Active Directory will be replicated between the 2 Domain Controllers.  IIS will not.  Follow the link above to configure your second DC as a fail over IIS server.
