Two DC's question

[Guest Dave Mc]

I have a very small network (15 workstations) with 2 servers (A, B) both of

which are DC's. "A" has all fsmo roles. When "A" goes down, users cannot be

authenticated thru "B". I thought, even with no fsmo roles on "B", the

network would still be pretty much functional when a DC went down ??

Is there something fundamentally wrong with my network ?

Probably your DNS is on server A?

 

Do you have DNS on server B?

 

You should setup DNS on the second server and add it to the list of DNS

servers on your AD clients.

Hi Dave Mc,

 

The problem is not FSMO roles. I think in this case you should check your

dns settings first. Is B server a DNS server? If it is, are the clients

pointing also to B DNS server?

Hello Dave,

 

Make sure that you have DNS server running on both DC's with AD integrated

zones and that the workstations configured to use both DNS servers. Not needed

for logon in your environment setup, but i would also make both DC's Global

catalog.

 

Best regards

You should make sure that SERVER B is a Global catalog server as well to

allow logon authenication if SERVER A down
