Exchange 2007 Extending Schema Questions. HELP!!!
Hello all,Have a couple of questions in regard to exchange deployment and cannot find the answers. Our company is looking to add exchange server 2007 into our environment (This will be placed onWindows Server 2008 64-bit OS). This server will reside on a separatebox internally. Currently our AD is housed on a Windows 2003 server. My questions are in regard to extending the schema. I was under the idea that I would add the new server as a member server and then run the prep schema switches on that box in the hope that the schema would be extended to the pre-exisitng domain. I have been told that that may not work. So,-How do I extend the schema?-Which box do I run the AD prep switches?-The windows server 2003 (Which holds our AD) is currently on a 32-bit OS. So if I was to run the switches on the 32-bit OS,I'm sure I would have to download the 32 bit version for 2003 and run the 64 bit switches on the 2008? Won't that cause a conflict?Thank you so much for anyone who can help. I only get one shot at this and don't want to cripple our entire domain!

The schema updates must be performed from a computer that's in the same domain and Active Directory site as the Schema Master. It can actually be done from the Schema Master itself (sounds like you've only got a single domain controller so it's not difficult to know whichdomain controller is the Schema Master, etc). However, since running the schema update from the Schema Master itself requires other software to be installed on it (like PowerShell, 32-bit Exchange management tools, etc) it might be a good idea to build a temporary workstation and run it from there.Have a read through these articles and post back with any specific questions.How to Prepare Active Directory and Domains 2007 Permissions: Frequently Asked Questions Hobson, Exchange MVP

HI,You can run /PrepareAD and /PrepareSchema switches on any domain controller or Domain member in the respective domain. That will replicate automatically in each other.Please let us information requested by Syed.You are trying to create new exchange organization; you can run those switches on that Windows 2003 DC. Download evaluation copy of 32-bit version of exchange 2007 and use that copy to extend the schema and prepare domain.RegardsChinthaka

Be sure not tio use the RTM version of Exchange but instead use the SP1 version. This is because there are schema changes in SP1 and by using the SP1 version you will apply all the schema changes you need at once.lasse at humandata dot se,
