Two domain controllers - yet when primary is down, domain still fails?

  • 772

I have multiple windows 2003 servers support a particular network, and when one particular server is taken offline, domain services begin to rapidly fail, such as users couldn't login.

What check list shall I look into to ensure that I can take my primary domain controller offline, for work, or any other reason, and have the domain still work as expected. I thought I had redundancy, but actually, it turns out that I didn't.

I'd like to look into this and figure out how to actually have redundancy for the domain services - and hints, tips, and comments very much appreciated.

  1. Please check all DC's are global catalogs. if not... a GC can not authenticate users.

    I moved the FMSO roles to another server to get around the problem I had with the original server.

    Authentications now work faster and logons are quicker, but I have not reached my aim of have 'complete' redundancy, but I have solved my problem doing this.

    Thank You
