How many Domain Controllers should I have?


A few questions about domain controllers.

I have 3 servers in my network, 2 are domain controllers - 1 is 2003 the
other is 2000.

q1) Is it good to have more than one domain controller?

q2) I recently restarted one of my servers, several of my users machines got
a message the "trust relationship has been broken" << something similar. I
think this is indicating one of my servers is not properly authenticating
users. Does this sound reasonable?

q3) My 2003 server has been starting to fail, I bought a new one from Dell
but I didnt make it a domain controller...

should I make it a domain controller? If so why?

Will it slow the server down? Its primary job is a database server for my
accounting system.

Thanks in advance.

Humour

YES, because of redundancy for the database where anything is stored about
users etc. Also think about to make the second DC a DNS server with active
directory integrated zones and DHCP server, split your scope to both DHCP
servers, to also have redundancy for this. Additional it should be a Global
catalog server.

Please give some more info about your domain setup, are both servers in one
domain or different domains in one forest?

Depends on your needs, is it also Exchange server, then it is not recommended
to make it a DC. How may user accounts do you have?

What kind of database do you use? SQL or Oracle or another one?

*** BOTH servers are in the same domain.

**** Please Validate this, given that my original 2003 server is starting to
fail I am inclined to make my new server a Domain Controller as well. Would
you agree this is a good move.

**** If you think I should please point me to an FAQ about how to make a
server not already a domain controller a Domain Controller.

*** Thank you.

Re: How many Domain Controllers should I have?

Hello humour,

On both DC's run dcdiag and netdiag to check for errors. If you have errors
please post the complete output here. Also post an ipconfig from the DC/DNS
server and one client.


For 40 useraccounts 2 DC's are really enough, just make them redundant with
DNS/DHCP and Global catalog configuration


SQL is not recommended to run on a DC:
http://download.microsoft.com/downlo...dmeSQL2005.htm
Scroll down to: 2.5.12 Installing SQL Server 2005 on a Windows Domain
Controller


http://www.pervasive.com/library/doc.../wgs-12-2.html
Scroll down to: Installation of Pervasive.SQL


So first you have to see about the SQL/Pervasive installation, before making
the server also a DC.
