Hmm, the only time I have ever seen this happen is when the cert exported from IIS did not prompt for a password for the private key. Turned out it had been a faulty cert.

It's driving me nuts. :( Thoughts?

You tell ISA what IP address to use and the interface is selected on that basis. Er.. Why do you want them to communicate with each other via the external interface? There can be no web proxy listener operating there an so no intra-array communications can take place. Do the certs exist on all array members? They must if you want to assign them to a VIP. -----Original Message----- From: isalist-bounce@xxxxxxxxxxxxx<mailto:isalist-bounce@xxxxxxxxxxxxx> [mailto:isalist-bounce@xxxxxxxxxxxxx<mailto:isalist-bounce@xxxxxxxxxxxxx>] On Behalf Of Jerry Young Sent: Thursday, October 23, 2008 7:18 AM To: isalist@xxxxxxxxxxxxx<mailto:isalist@xxxxxxxxxxxxx> Subject: [isalist] ISA Server 2006 Intra-Array Communication All, I seem to recall reading something that talked about a Registry entry that can be used to tell ISA Server which interface to use for intra-array communication. This is not the same as the UnicastInterHostCommSupport Registry value. Right now, I'm in the process of standing up a pair of ISA Servers in an array but am waiting for the network engineers to properly configure the switch port to which the external interface on one the servers is connected. Until that time, the two servers can't communicate with each other over the external interfaces. I'm running into some strange behavior (machine certs sometimes show as installed correctly, not installed correctly, or can't be found) when attempting to assign a certificate (different from the machine cert) to a listener that runs on top of an NLB VIP on the external interfaces and I'd like to rule out network connectivity between the two as a potential cause. Does anyone know of which I write or did I somehow muddle and morph something I read into something that doesn't exist? -- Cordially yours, Jerry G.
