The OCS Automatic Sign-In Troubleshooter programmatically performs DNS lookup’s for all the DNS records that the Office Communicator 2007 client uses to locate an OCS 2007 server, and displays the results. The tool performs the DNS queries as the client would (e.g. using the client DNS settings and cache), so that the results will reflect what Office Communicator will use. If people find the tool useful, I will add more functionality.

Thanks for creating this! Will definitely be using this as it’s less subjective to typing errors.
This is a great debugging tool. Thanks for creating this and sharing it with everyone. I’ve added it to my collection of OCS goodies that I use for troubleshooting.
Thanks for the help in sorting why my automatic sign in did not work!
Great tool – thanks for making it available. I like the fact that it queries all possible records and shows which ones match. My issue was a DNS A record that was being picked up that I didn’t no existed.
Nice. This should be a heck of a lot easier to point clients at rather than trying to walk them though doing the NSLookup and being subjected to typos.
