Adding member servers to Small Business Server 2003 R2 Premium

Hello,

We have 1 SBS 2003 R2 Premium server in operation.  I am trying to setup a second server for redundancy purpose and not having to depend on just 1 server (God forbid).

1) When adding member servers to Small Business Server 2003 R2 Premium, what type of servers can I use?  Can I use servers with W2K3 R2 Enterprise and add as a member or does it have to be the same type of Operating Systems (SBS 2003 R2 Premium).

2) What would be the best way for me to replicate the first server to the second server.  SBS does not allow trusting between Domain Controllers, right?

3) The reason for having the second server is also for the second server to server as Secondary controller and Secondary DNS.  Can I set this up under an SBS 2003 network?

4) I see the NLB option in SBS, does this mean I can just configure another box of SBS and let them load balance each other?   If so, how would I go about configuring it.  

Thank you in advance for your help.

Any version of Windows 2003 is what you want... you cant use SBS ... you can only have one SBS server in a SBS domain...

Yes, you can not have trusts in SBS... but you can run DCPROMO on the second machine and have a second DC...

Yes, run DCPROMO on the second windows 2003 server.  Later, after it become DC, make it a DNS server (add programs-- windows components)  Also, make sure to update DHCp and have your clients point to both servers for DNS.

No, only one SBS server per SBS domain...

Great! Perfect answers I was looking for.

4) Why NLB is being offer in a SBS environment?  What is a typical Network Load Balancing scenario in SBS?

By the way, NLB is not the same as clustering, right?  Does SBS 2003 R2 Premium supports clustering also?

I don't think you can cluster with Windows 2003 SBS.

NLB is network load balancing...  You can create NLB with SBS and another server if you want... but this won't load balance anything like Exchange...or FMSO roles...  If you want you can configure the SBs server and another server to NLB web traffic (for example) if you have the same website on both servers...

Thanks very much.  So NLB only applies to Web services then?  Since it doesn't do any good for Exchange and SQL or CRM, it's almost useless?  I mean beside Web what other services can benefit from NLB?  I know I am going off topic a bit, but this is the last question... I promise <grin>

any service or application can benefit from NLB...  however, you would have to make sure that the services can work properly under NLB...

It is real good for read only data...  like a web server...  I also use it for Terminal Servers...  

NLB creates a virtual IP address..  this allows you to tell you clients to point to the virtual IP...  

NLB redirect the virtual IP to one of the servers in the cluster...  

I would recommend not using this feature in your environment.  Normally, you will only need this in larger environments... not SBS environments...
