I need to retire a particular piece of hardware, I have another server online on this particular network.

I have run DCPromo om the new server, but when the original server is shutdown, authentication on the network fails. I have also made the new 2003 server a global catalogue, and authentication still fails.

I would like to know how I can 'retire' the old server. It may need to stay on the network for legacy reasons, but I would dearly love to remove all domain activity from it without any downtime.

I look forward to help in this regards! Thanks for your tips hints and comments.

transfer the FSMO roles to the new server, then demote the old server using dcpromo again

you may also want to check the replication status of your new server using repadmin /showrepl

I am currently moving RID, PCD, and Infastructure roles to a secondary 2003 server, with buckets, and buckets of bandwith. I am assuming that, this should improve the domain performance? – Mister IT Guru Jan 25 '11 at 12:01
Improve the domain performance in what way? What performance problems are you having that you attribute to the domain controller? – joeqwerty Jan 25 '11 at 13:06
The Domain Controller also has other applications that have been put on it such as exchange tomcat, and mysql (management decisions). I want to move all domain related roles away from this server, to another server that does nothing except these five roles. Am I missing the mark here? – Mister IT Guru Jan 25 '11 at 17:25
No, I think that's a wise choice. Use the DC for DC related functions and use application servers for applications. – joeqwerty Jan 25 '11 at 18:03
which version of exchange? you wont want to demote a DC with exchange 2007+ on it, instead install exchange on a new server and migrate – BoyMars Jan 27 '11 at 11:04

Don't forget to add the new DC to the client ip settings for DNS, assuming your DC is also your DNS server.

I added this system to the DHCP settings - Thanks for reminding me. – Mister IT Guru Jan 25 '11 at 17:25
