Exchange Outlook Web Access Proxying across CAS Servers
In many larger environments, Exchange 2007 may be deployed with multiple Client Access Servers (CAS) across the AD site boundaries. The common configuration is to have users access one CAS server from the Internet and it proxy the request to a different CAS in the AD site where the user’s mailbox is located. The Internet facing CAS server should have the Internal URL populated with Forms Based Authentication (FBA) and Basic Authentication enabled. The External URL is optional. The authentication ......

Redirection for Outlook Web Access with IIS 7 for Internal and External URLs
Http to Https redirection is commonly a preferred configuration for Outlook Web Access for most organizations. The challenges presented in IIS7 are that the built-in redirection feature only allows relative redirection without a full URL entered. To perform Http to Https, the full URL is required. This becomes an issue when organizations are trying to redirect for both internal and external users who commonly are using different URLs to access the server. The solution is 2 fold. First, turn on relative ......

To P2V or not to P2V
With the release of Windows 2008 R2, highly available Hyper V deployments have increased in popularity. One of the big questions during these deployments is what to virtualize and what to leave on physical hardware and in particular when it refers to domain controllers. Domain controllers are basically highly transactional database servers which service most basic network functions including authentication, name resolution, replication, and of course many secondary services like DHCP or Radius. In ......

Publishing Multiple URLs to Outlook Web Access in ISA 2006 while keeping it hidden they exist on the same server
This week, I had a pretty strange request. An organization wanted to host multiple Email domains in their Exchange environment while keeping it hidden from external mail users and outside parties. Same organization was ok, same AD and Exchange servers were not. The mail flow portion was pretty simple. Added a new accepted domain to Exchange 2007, to the spam filter appliance, configure LDAP for this new SMTP domain, and change the primary email address for certain users. I used an email policy that ......

Exchange 2007 Routing Group Connector Mayhem
Recently while performing the initial steps for an Exchange 2003 to 2007 migration, I ran into one of the more frustrating issues with Exchange 2003 to 2007 transitions. Broken inter-organization mail flow. After banging my head against the wall for a few hours, and sending enough test emails to get added to who knows how many OBLs, I finally stumbled on the answer. Exchange 2007 could talk to the 2003 environment as well as route mail outbound to the Internet, however all 03 to 07 mail was getting ......

Recovering to a SCR Standby Server in Exchange 2007
Recently after deploying a highly available Exchange 2007 solution for a customer, I had to test recovery procedures and create a recovery document. Since I was already documenting my steps, I figured I’d share them here as well. NOTE: This environment consists of a CCR mailbox cluster and a MS NLB cluster with the Hub Transport and Client Access Roles at the production site. The DR site has a server containing the mailbox role and an a server with the Hub Transport and Client Access Roles. 1. First ......

Windows 2008 R2 support for Exchange 2007 on the way
Seems there has been a large enough uproar from the IT community for Microsoft to announce intentions to support Exchange 2007 on the newly released Windows 2008 R2 OS in the near future. “We always talk about listening to customers and sometimes this is written off by many as 'marketing speak'. In fact, we do take feedback seriously and no input is more important to our engineering processes than your voice. Earlier this year we made a decision in one direction, and due to the feedback we have received ......

Battling Slow Login Issues
Recently, I had an enterprise customer who was experiencing intermittent and random slow logins across the network by users with Windows XP workstations on a Windows 2003 network. The customer had been fighting this issue for over 2 years and had allocated plenty of different resources towards it throughout that time frame. Upon first diagnosing the issue, corrupt profiles, corrupt group policy objects, or even network infrastructure all came to mind. The first course of action was to actually find ......
