UC Certificate Partners for Exchange and OCS 2007

jkruse — Fri, 08 Feb 2008 02:32:04 GMT

Exchange 2007 and Office Communications Server 2007 have strict requirements for external/public certificates - specifically the use of Subject Alternative Name (SAN) certificates, aka Unified Communications Certificates.

We have a KB article (kb929395) which lists some of the providers of these UC certs.

INTRODUCTION

Microsoft works with public X.509 certification authorities (CAs) to make sure that Microsoft Exchange Server customers can obtain the certificates that they require in order to use Microsoft Exchange Server 2007 for the Domain Security feature to enable secure client access from the Internet.
Microsoft also works with CAs in order to make sure that Microsoft Office Communications Server 2007 customers can obtain certificates that they require for Communications Server 2007 servers.

Scott Schnoll has a great post on the differences between the various versions of Exchange 2007.

He also sheds light on one of the most commonly asked questions - can you upgrade from the Trial version to Retail? (the answer is yes)

Exchange 2007 Mailbox Server Role Storage Requirements Calculator

I feel like I'm always plagiarising You Had Me At EHLO recently, but this is gold and I highly recommend you check it out...

In order to assist customers in designing their storage layout for Exchange 2007 (especially after publishing this blog post), we have put together a calculator that focuses on driving the storage requirements (I/O performance and capacity) and what the optimal LUN layout should be based on a set of input factors.

The calculator uses all the recommendations outlined in the following articles, and thus we recommend you read them before utilizing the calculator:

Storage Requirements Blog - http://msexchangeteam.com/archive/2007/01/15/432199.aspx
Processor & Memory Requirements Blog - http://msexchangeteam.com/archive/2006/11/27/431644.aspx
Understanding Exchange Server 2007 I/O improvements from 64 bit - http://msexchangeteam.com/archive/2006/09/08/428860.aspx

The calculator does not make any recommendations toward storage design (RAID parity, number of disks, etc) as the storage design is largely dependent on the type of storage array being utilized. For more information on some basic requirements around storage design, see the Storage Requirements Blog post listed above.

Exchange 2007 Tip O' The Day (not updated daily)

jkruse — Fri, 24 Nov 2006 05:07:00 GMT

When you install Exchange 2007 for the first time, you need to extend the AD schema (usually by running setup.com /PrepareSchema, or just setup /ps if you’re lazy like me).

Make sure you do this in the same AD site as the schema master, otherwise you will get the following error:

Setup needs to contact the Active Directory schema master but this computer is not in the same Active Directory site as the schema master (XXX).

(XXX being the AD site)

So how do you find out which actual server is the schema master? Well, I’m glad you asked.

First make sure you have the appropriate permissions, then run the following command:

regsvr32 schmmgmt.dll

This will enable you to add a snap-in to MMC called “Active Directory Schema”. You can then right-click, view Operations Master, and either find out which server is the current Schema Master or transfer the role to another server.
