Testing plan for 3 domain controllers

I know i can use dcdiag just looking for a plan and also which switches to use

I also want to check replication with repadmin /showrepl is this the best way to check replication?

Do not run
repadmin /showrepl

Open in new window

rather run
repadmin /showrepl *

Open in new window


There's AD health PowerShell scripts that you can schedule too

Are these three new DCs in a pre-existing domain or are you building the forest from scratch?  Virtualized or physical?  How many sites?

Thanks Shaun will check it out

@Jason these are preexisting virtual servers, just the one site

In that case you don't need anything fancy.

1. run cmd.exe as administrator and run dcdiag.  Address issues as needed.

2. Configure NTP.  On your PDC run these commands:

net stop w32time
w32tm /configure /syncfromflags:manual /manualpeerlist:"0.us.pool.ntp.org,0x1 1.us.pool.ntp.org,0x1 2.us.pool.ntp.org,0x1 3.us.pool.ntp.org,0x1"
net start w32time
w32tm /configure /reliable:yes /update
w32tm /resync

On secondary DCs run this:

w32tm /config /syncfromflags:domhier /update

3. Set the primary and, if required, secondary DNS servers and assign static IP.  Point here is to replace the loopback IP.

4. Disable the built-in administrator account and recreate by copying the AD user.  That's half of a set of credentials and everyone knows the value.  

5. Check your replication health using repadmin as you mentioned.

Anyone else want to add to this I'm just going off the top of my head.
