We have a domain with 1 SBS2003R2 server. A new server is being installed for SAP with Windows Server 2008 and SQL server. I am having an argument with the SAP supplier where his network specialist claims it is not recommended to install a 2nd DC in a SBS2003 environment (AD issues, Exchange issues ,etc), and should only be done in non-SBS environments, or with a Read-only DC in a remote location part of a SBS domain. Is this true or not ?
Would anyone have links to Microsoft documents that clearly indicate wether it is recommended or not ?
Although I found many documents explaining how to accomplish this, would it be possible that this is not a "Best Practice" thing to do ?
