Ready to install a Small Busniess Server and get off this peer network

We have 25 users and PCs on a Network they all below to a workgroup and we use a SonicWall firewall (

SonicWall firewall is doing DHCP DNS for us.
The LAN range is -

I want to install a Small Business Server 2011 and have the server do DHCP and DNS

PCs are Windows 7 Prof. and will join the domain using 20 new A.D. accounts
We also have 5 network printers that will be managed by the new SBS

We are not going to use Exchange so I am not going to install it

I'd like to set up this SBS now as much as I can and then over the weekend join all the PCs to this new domain.

I know I cannot have two DHCP and DNS servers on the LAN
I'm trying to get as much as I can done now and then finish up on the weekend

Can I install the SBS DHCP and DNS using the same LAN 192.168.254.XXX and simply turn these services off on the SBS for now
then when ready turn off DHCP and DNS on the firewall and turn SBS DHCP and DNS on when ready?

or should I leave DHCP and DNS off the SBS then later install these services?

Any suggestions are appreciated

There is no problem having the second DNS server running, it will be needed for AD and other stuff on the SBS box to work, and would cause problems if disabled. I would suggest you proceed as follows:

1. Set a short DHCP lease on the SonicWall. Looks like the default is 24 hours, but it may have been set for far longer. This needs to be done well in advance, at least as long as half the lease time. I would go for one hour.
2. Set up the SBS box with DNS.
3. Set up DHCP, but leave it unactivated. Use a one hour lease.
4. Test a workstation with manually entered IP settings the same as the new DHCP server will be distributing.
5. Once it has been confirmed that the new DNS server works, and a client can be joined to the network, authorise the DHCP server, and kill the one on the SonicWall.
6. Wait 30 mins (half the lease time) for client machines to renew their lease.
7. Go ahead and add the machines to the domain.
8. Set the DHCP lease on the SBS box to something  more sensible, the default of 8 days would probably work well.

The reason for setting DHCP leases is to ensure that changes happen in a reasonable time.

You will have to install exchange. SBS is meant to work together with exchange as a packet. If you don't install it that will make the server unstable. It is also against the SBS license agreement. The same applies to sharepoint, which is also part of SBS.

Of course you aren't forced to use exchange. But it has to be installed.

I'don't be curious to know where in the world you found a new copy of SBS2011 to install since Microsoft quit selling it 2 years ago.  

Turn off DHCP on your firewall router and plug in your new server and complete the integrated install.  SBS must be connected to the Internet to install.

SBS can then provide DNA and DHCP for all devices on the network, even if they are not joined to the domain

Ok, sounds like I can simply turn off DNS and DHCP on the Sonicwall
Install my SBS with DNS and DHCP. All my devices using DHCP will eventually use the server DHCP and DNS. Question will the PCs start to use the server's DHCP and DNS after they reboot or does the IP address release and renew on their own? also all the printers have a static IP assigned can I simply reserve these IPs on the server DHCP later?
the last part would be to join all the PCs to the domain correct?
Cris HannaSr IT Support EngineerCommented:
With the previous DHCP server unavailable devices should automatically look another but release renew may be required.   Depending on the IPHONE addresses assigned to the printers, or just exclude if they are all in the same relative range.

So where did you find a copy of SBS if I can ask?

If you aren't going to use Exchange then I'd definitely go with Server 2012 R2 Standard. At 25 users, you are at the very outer limit for Essentials, so that wouldn't be a good fit. SBS 2011 Standard is older (based on 2008 R2) and as someone above stated, it is designed with Exchange baked in, so using SBS without Exchange is not good *and* is actually more expensive than the Standard license. SBS CALs are also more expensive.  You are paying a lot more money for something you won't even use.  If you like the "SBS" like dashboards and wizards for managing things, you can install the Essentials Experience role on 2012 R2 Standard and get all of that goodness, but without the 25 user limit. It's the best, most cost effective solution for your situation.
I'm just going to chime in here to second Malmensa's procedure. Extra DNS servers during the transition are not a problem, but eventually you want to consolidate DNS services to the one(s) integrated with Windows Server.

You can have more than one DHCP server as long as they assign IP addresses out of separate pools. Again, you would want to eventually consolidate DHCP services onto the one offered by Windows Server.

Windows Server 2011 SBS is available for download for downgrade rights to people who purchase a volume license Windows Server 2012 Essentials, so it's not really much of mystery of where one can get it.
Cris HannaSr IT Support EngineerCommented:
Actually with SBS if it detects another DHCP server it will shut it's own DHCP server down
David AtkinTechnical DirectorCommented:
Chris is correct regarding the DHCP.  SBS will detect that the sonicwall is running DHCP and then stop its own DHCP Service.  You will have to stop the Sonicwalls DHCP Server prior to running the Connect to the Internet wizard in the SBS Console.

Leave DNS Enabled on the SBS.  DHCP will auto disable as per the above.

You can do most of the work setting up the SBS prior to deployment.  However if your goal is to do this at weekend then you're really pushing it.  Installing the SBS updates alone is going to take about a day at least.

I'd also second the other comments about moving to Server 2012 Standard (with the Essentials Role) opposed to SBS 2011.  If you're not going to use Exchange then there isn't many (if any) benefits over using SBS 2011 over Server 2012 Standard.

Also can I install SQL 2008 R2 Standard on a SBS2011 ?
