Hi All ...... I have only ever had to architect systems for single server or single site setups.

One of my clients, who currently have a SBS 2008, are looking at bringing on remote sites so I am looking at options as far as additional Servers and how best to manage this requirement.

I am not sure on the questions to ask, so EE assistance is appreciated.

SBS will work in multisite configurations. Ideally you want a site-to-site VPN set up with suitable routers between the SBS site and each of the remote sites, and then although it is not necessary, installing a domain controller which also provides DNS at each site will allow for name more efficient resolution and authentication, and fail-over protection if the VPN is off line. All resources can then be accessed as if in the same office via the VPN ecept of course performance for file access is dratically reduced. Often you may want to place file storage at each site or replicate it using DFS. DFS works well but there are no file locks, so if multiple users may be editing the same files at the same time it may not be an ideal solution. Sharpoint which is built into SBS can also be used for file access. Exchange will work fine at each site just the same as if in the primary office.

One note you can only have one SBS in a domain, but you can add as many member servers or DC's as you like.
Some tims on adding the additional servers:
Add an additional server to an existing SBS 2003 domain:
If the new server is a newer version such as server 2003 R2 or server 2008 you first need to run adprep, on the SBS, from the new server CD set to "extend the SBS schema".
If the new server is server 2003 R2adprep  it is located on the second CD under \CMPNENTS\R2\ADPREP\
If Server 2008 see: http://www.petri.co.il/windows-server-2008-adprep.htm

-Make sure the SBS is fully up to date with all patches and service packs, which makes it more compatible with the new O/S's (2008, Vista, Win7)
-You need to create a computer account for the new server, on the SBS, using the wizard located under server computers in the server management console of the SBS
-If the new server has more than one NIC, disable all but one while joining the domain. Once completed you can enable others
-Then point the new servers DNS only to the SBS, and join the domain using the wizard  http://SBSname/connectcomputer
-If the new server will not join with connectcomputer (I don't believe 2008 will yet), add it manually under My computer properties / computer name / change, and then in Active Directory move the computer from the Servers OU to the MyBusiness/SBS servers OU
-If you wish the new server to be a domain controller, now you can run DCpromo on the new server. You must use integrated zones when working with SBS. (there are different options in the wizard, just choose defaults and integrated). I would recommend at the same time installing DNS.
-If the server is going to be a terminal server (DC and TS is not recommended) you can add the Terminal Server and TS Licensing Server roles now.

Thanks.

You have included instructions above if the SBS is a 2003 box, but is the process specifics different for our SBS 2008 box?

The remote site is only a few Users, so is it actually worth setting up another DC or member server, or are there better ways to go about this. This client will be 'acquiring' a few small businesses like this, so having a plan would be good.

There is no need to ad a server to any of the remote sites, but it allows you to continue havinginternet access if the VPN is down, allows for faster logons, local caching of redirected by documents, and DFS if needed. Basically it improves performance.


The process of adding servers to an SBS 2008 domain is basically the same:
Add an additional server to an existing SBS 2008 domain:
If the new server is a newer version such as server 2008 R2 you first need to run adprep, on the SBS, from the new server CD set to "extend the SBS schema" on the SBS 2008.
It is located on the second CD under \CMPNENTS\R2\ADPREP\

-Make sure the SBS is fully up to date with all patches and service packs, which makes it more compatible with the new O/S's (2008, Vista, Win7)
-If the new server has more than one NIC, disable all but one while joining the domain. Once completed you can enable others
-Then point the new servers DNS only to the SBS, and join the domain using the properties page of "computer"
-In Active Directory move the computer from the computers OU to the MyBusiness/SBS servers OU
-If you wish the new server to be a domain controller, now you can run DCpromo on the new server. You must use integrated zones when working with SBS. (there are different options in the wizard, just choose defaults and integrated). I would recommend at the same time installing DNS.
-If the server is going to be a terminal server (DC and TS is not recommended) you can add the Terminal Server and TS Licensing Server roles now.
