Event ID 87 in Exchange 2010 with OCS Integration

Recently while installing Exchange 2010 in a customer environment I ran into an error related to certificates when I tried to enable the OCS integration in OWA. The client had chosen Godaddy as their public CA of choice and as it turns out this played a role in causing the issue. Godaddy used a ” symbol in the issuer field of the certificate. Although it wouldn’t normally matter, it does when you are using that field in an XML config file, like the one used for IM integration with OWA/Exchange 2010. Continue reading

One way messages with federated partner and ID 504 in Communicator

Since the blog I did on Live Meeting troubleshooting I have seen a lot of queries leading people to the site for troubleshooting OCS. I’ve also seen a ton of questions on the subject on the MS forums. All this has lead me to the conclusion that OCS troubleshooting isn’t that easy to get a handle on. With that in mind I’m writing this post on troubleshooting federation. First and foremost, this article is about troubleshooting a mistake I made during a deployment recently, and if you ask any PSS engineer they will tell you 80% of the problems they face with OCS are based on the same thing: human error/configuration error. As I said in my last troubleshooting post, I’m no expert on troubleshooting OCS, but hopefully this post will help someone out there. As always I encourage you to share your stories and methods if you think they may help someone else.

What to do when your customer’s WAN is actually firewall to firewall VPN’s

Recently I began planning for a centralized deployment of OCS that would sit in one of 6 offices for a client we’ll call Acme Accounts. Acme will start out using OCS for IM, P2P audio/video and Live Meeting; eventually OCS will grow into a full blown enterprise voice solution. The first big hurdle for us when designing Acme’s OCS implementation was their “WAN”, instead of typical MPLS or point to point connections, Acme uses its internet connections and ASA firewalls in each location to create VPNs that allow traffic to route between sites. The latency created by this solution has never been an issue, but voice and video were never running over this connection either. Continue reading
