Multiple OWA on one IP (no front end back end)

We've had a single Exchange server behind an ISA for awhile. OWA was set up with certificates yada yada. Well. We added a new Exhagne server and anyone on said new server cannot get thier webmail. I created a new certificate for the new exchange server and hooked the certificate onto the ISA server with a new listener. However all requests for the old domain name seemed to want the new certificate. I jiggled a few settings and got the original cert back but is there a was I can trick ISA into allowing both servers to pass through. What if I instaled the older certificate into the new exchange server IIS?

I tried putting the old certificate in the new server, it asked for a secoind login and didnt return all of the proper stuff..images missing, red x's etc
Are the servers using the same dns name? could be a client issue.
Tennessee_PrideAuthor Commented: server has been published via ISA as The new server I was going to publish as however the ssl listener is using the certificate and if I try to create a new listener using 443 it gets all testy and says that the current rule is using the certificate. Basicaly, two internal exchange servers in a non-front end back end configuration trying to publish both OWA sites out of one IP address

hmm, if it's the same iP you should be able to use the came cert, and dns name.
a second cert will only confuse the boxes. and the client machines.

Every time you try to load it, it should give you an error, saying you already had x cert for this box, instead of this one....

So theoretically

External DNS ( ---- (webmail cert on listener)ISA ----------Exchange 1 (webmail cert on IIS) ------- Exchange 2(webmail cert on IIS)
these exchange servers are on different subnets

should I change any hosts files?
I think you will run into problems with this configuration.  Have a look at this document for an indepth explaination.  I'm not sure if there are other solutions.

hmmm..I was using Forms based authentication. The walkthrough said to set it for Basic. If I set it or basic and set the exchange http to use forms then one works fine (original one) and the second one gives a 440 login time out error. If I turn off basic on ISA and use Forms then the original exchange server works fine but the second one returns links with no images (red x'x) and a login box on the left colum if you ty to go to any link. very strange stuff..Ill keep bangin on it
