Hey,
Need some help please as I cannot find any helpful documentation on this situation.
I have 3 domains in 3 country's. US and Australia has a working Lync 2010 deployment, and we have just added a new site in the New Zealand domain with Lync 2013 (eventually the other sites will be migrated to Lync 2013). The Lync 2013 Front End has been installed and all services are running. I have enabled the first test user in the Lync Control Panel successfully . When I go to sign-in I get an error along the lines of "try again or check with your administrator". On inspection of the client logs I can see that client sends a SIP register, the server responds with the available authentication methods, the client then trys again with using Kerboros and the server responds with SIP/2.0 404 Not Found - ms-diagnostics: 4005;reason="Destination URI either not enabled for SIP or does not exist". The use account is valid and I can log on to a workstation successfully with the same account.
We have not yet run enable-cstopology on the Lync 2010 FE's as this is not normally required. However to be safe this is currently going through change control. Something that isnt common in a migration is adding a new SIP domain (for New Zealand) and new meet and dialin URL's. This makes me think that running enable-cstopology on the Lync 2010 FE's will fix it.
The other thing that springs to mind is domain secuity on containers and OU's etc.
Any ideas would be greatly appreciated.
