Debugging an OCS installation just got easier

I might be realy slow in discovering this, after all it has been some months since I last touched an OCS installation. I seriusly wished I had this tool when I was last time thou.

This tool just like the Exchange testing tool, will show all the steps involved in connecting to an OCS system and produce any errors and confirmations that everything is working, excellent for debugging or even just validating that everything is working as it should. I found the link to the tool on a new danish UM experience sharing group (all danish) http://www.colabora.dk/.

The actual tool can be found here: https://www.testocsconnectivity.com/

Thought I would also add some extra info and show what the tool can produce of results (FQDN’s and IP’s changed)

How to get external SAN UC SSL certificates that work with OCS 2007 R2 and avoid having to read 100 blog posts!

Been reading up on external and internal DNS names used by OCS 2007 R2 ? Your head stopped spinning yet? So you’ve decided on what FQDN’s to use, next step order some SSL certificates, should be easy enough right, You allready figured out You need SLL certificates that are Unified Communications Certificates (UCC) enabled. In my example I will use GlobalSign Domain Validated SAN’s, if I needed multiple domains for example for @sole.dk and @soleit.dk, I would choose GlobalSign Organisation Validated SAN’s instead.

For a GlobalSign SSL certificate to be UCC enabled, it must use SAN domains, no other way of enabling it. So no point in spending lots of budget on seperate SSL certificates for each service. SAN Subdomains are also quite alot cheaper than buying seperate SSL certificates.

One of the tricky parts of Office Communications Server 2007 R2 and SSL certificates, is that You can not use one single SAN SSL for all services, if You intend to use port 443 for all services!

Why would we only use port 443 ? Read the rest of this entry »

Todays update from Microsoft (KB974571) makes Office Communication Server think it is an expired evaluation!

The updates I mentioned in a previous post here http://www.sole.dk/post/microsoft-security-bulletin-for-october-2009/

Happened to have an update that kills Office Communication Server 2007 all editions (R2/Standard/Enterprise) and Live Communication Server 2005 (and SP1 edition).

The error that comes up in the event logs is that the server believes that it is an evaluation and just expired with this message: “The evaluation period for Microsoft Office Communications Server 2007 R2 has expired. Please upgrade from the evaluation version to the full released version of the product.”

I also got this message in the event logs: “Error Code: C3E93C23 (SIPPROXY_E_INVALID_INSTALLATION_DATA)”

Event ids logged: 12290 Read the rest of this entry »
