"403 - Forbidden: Access is denied." when accessing Exchange Control Panel (ECP)

I am running BIG IP VE 10.2.2, and have published Exchange 2010 using the Template Wizard. I can acces OWA fine, but when I try to view the ECP by going to Options > See All Options, I get the following error:

 

 

"403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied."

 

 

I have tried enabling Windows authentication on my ECP vdir in IIS with no luck. Anyone have any idea why this is happening? I can access the ECP just fine when bypassing the VIP and pointing my browser directly to the CAS, or when using TMG.

 

 

Thanks,

    ECP should be setup for forms-based authentication, is it? Are you accessing the entire Exchange using TMG? There are lots of different caveats depending on your configuration/deployment.

    Yes, both OWA and ECP are setup for FBA. I have a second web site with a second set of Exchange vdirs and authentication settings that I point my TMG server to. No traffic going through the F5 traverses TMG before or after.

     

     

    I also have another NLB from another manufacturer, and when I point DNS to its VIP, ECP works fine. It seems to be something with the BIG IP.

    Nevermind, I found the problem.....the ECP IIS vdir was still set to require SSL :-)
