AD replication

   Let me say this i am very new at server work and most of the servers that i support are single stand-alone servers most of them sbs's 2000 or 2k3.
here is the question. I just installed new sbs 2k3 std server but i want to use the old server for replication of data and AD so if my main goes down the only thing i loose is my exchage.  I know there is a way to do this.  I have already gotten std server 2003 to upgrade my old server.  
    My plan is to run my server based applications, company shares and user files from the old server so that my new one only has AD, DNS, DHCP, Exchange etc. to run.  If anyone has any help or a better plan any help with this is greatly appreicated.

Is the old server an SBS box too? If so, it is not possible to install two SBS Servers in the same domain and have them replicate. If you have an SBS in a domain it must be the first domain controller installed and cannot have the FSMO roles transferred from it.

What you can do is rebuild you old server as a new Windows 2003 server (NOT SBS) and join it to the same domain as your new SBS box - either as a domain controller, or as a member server. To do this run DCPROMO an follow the prompts to create a new domain controller in an existing domain.

    Thankx, yes someone had already told me that i couldnt run sbs on both servers so i got the regular server 2003 for the old one to run off of.
     Can you tell me the difference between a member server and a dc. I want redundancy so which one will work in this situation better.  
     I want it so that if my primary goes down my secondary will pick up right where the primary left off (without any human intervention) and the only thing i will loose will be exchange.

A member server is simply a server that is joined to the domain (IE participates in domain authentication).
A Domain Controller is a server that a copy of the active directory database and can respond to authentication requests (if configured to do so)

You can't get full redundancy of all SBS services, but you can configure the new server as a domain controller, make it a global catalog, a secondary DNS and a backup DHCP. You could even install exchange on the new server and have a complete Warm swap solution.

I am really looking to have at least AD AND DNS as a not sure what the global catalog is but again what i want is if my primary goes down my secondary pick up on auth, and dns along with my company and user files

In which case here is what you do:

Build new Windows 2003 Server and join it to the domain as you would a workstation or other server.
Give it a fixed IP address and point it's DNS settings to the existing SBS server ONLY
Install the DNS service from the Windows 2003 CD
Patch it fully
Run DCPROMO on the new server and configure it to be a NEW DC in an EXISTING DOMAIN.
Use REPLMON from the support tools pack on the Windows 2003 CD to check that the server is fully replicated (no red icons!)
Open AD Sites and Services tool and navigate to the NTDS Settings object under each server in the site you are using (probably DEFAULTFIRSTSITE), rightclick on the NTDS Settings object and select properties and make sure Global Catalog is ticked for each server.

Open up the DNS snapin on the new server and make sure that the AD integrated forward lookup zone for your domain has copied across

Change your DHCP settings to give out both servres as DNS servers

Change the SBS server DNS settings to point to the new server as primary and itself as secondary - do the opposite on the new server, so that each server points to the other as primary and itself as secondary.

If ANY stage fails, stop and tell me what happened.

will do, thanks for all the help so far i will be out of the office on service calls till tuesday when im back in the lab and i can do this on a test server
will post back then, again thankx for the help so far
JasonBrantley
Welcome, let me know how it goes

Cheers

Sorry bout taking so long JamesDS had to go out of town unexpectedly, I ran the ad rep. wizard, (DCPROMO) but once it was finished the only thing it replicated was the default items NO user info was replicated at all. (This was ran between a SBS 2003 server and a box with server 2003 std.)

Might this be because SBS2003 doesnt keep anything in AD? To view user info you have to go to server mgt then users.  

I have since ran a test with another set of servers both running server2k3 std and AD rep went perfect.

Any Idea's on how to get SBS2003 to replicate AD or if its even possible?

Thankx TG

I am pretty possitive that AD didnt replicate when i go to AD on the backup (std 2003 server) all that is there are the standard items with no user data (ie. user account names, groups etc.) I'll be back in the lab on Friday so Ill post back then.
Again thankx for the help
TG
Sorry for the delay in getting back with you JamesDS, had to go out of town on emergency.  I am still having problems with getting it to replacate with a SBS2003 server to Server2003 std.  but I need to close this question so thankx for all the help
