We get lots of questions on our forums and lots of calls to our support staff about installing FSE and Antigen on clustered Exchange servers. Obviously, installing on clustered servers is a whole different animal from installing on single servers and requires additional guidance.
In response to that need, our UA team produced cluster install guides in 2008 for FSE and Antigen. These guides give you system requirements, step-by-step installation guidance for installing on several different types of clustered servers, upgrading guidance, and step-by-step guidance for uninstalling FSE and Antigen from clustered servers.
The guides can be found in our technical library on TechNet:
Forefront Security for Exchange Server: http://technet.microsoft.com/en-us/library/bb892168.aspx
Antigen for Exchange: http://technet.microsoft.com/en-us/library/bb913988.aspx
Our excellent support team has also written many Knowledge Base articles about installing FSE and clusters that you may want to review before installing FSE on clustered servers or if you are having problems with FSE on clustered servers. These include:
If you have feedback on the guides or any of our documentation, please send us a note at email@example.com.
Be safe out there-
