While troubleshooting push notification failure issues with a client, I found an interesting problem.

Recently I was working with someone from the technet forums to test their open federation. I added the contact to my list and sent them a message and immediately received the dreaded 504 error in MOC. Since this has been a hot topic on the forums and I see lots of searches landing people here for 504 errors I wanted to share again. I began the troubleshooting process by starting a new debug session on my edge server to grab a SIP trace (see my previous article on the same subject here for more information).
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.
