We have an Exchange 2007 SP2 Enterprise server whiich was recently migrated laterally into new hardware from a Server 2003 box. The new hardware was freshly installed with Server 2008 R2 Standard SP1 on an Intel Mod Server running ESXI 4.1, and has been completely updated to within the last 30 days.
We are also runing an Edge server in front of this server.
Since the migration though we have been having issues with Autodiscover not working correctly and all the issues which go along with this.
Some of the issues have to do with users when they move their laptops from wired to wireless connections within the building (still attached to the domain) then back or vice versa - they have to re-authenticate back to the exchange server - as they are prompted with a login box instead of just getting connected again.
Also the OAB is not syncing correctly to the users within the environment - most of the time when initiating a sync with the OAB - it just fails after taking a long time to contact the server.
The offline address book looks to be installed correctly, and there is a publlc folder database which is mounted and working correctly - but I get errors when running the best practice analyzer tool.
Also the OOF (out of office assistant) on Outlook will stop working - still works in OWA, just not in their Outlook 2007 clients, and it generates an error stating the server is not available at this time when attempting to open the OOF.
I understand that some of these issues are Autodiscover in nature, but others could be unrelated ,and we just need to start looking at best practices and work our way down to make sure that everything is set up correctly, and that we can get the environment healthy and operating as expected.
Also when runnign the Exchange Remote Connectivity Analyzer tool for autodiscovery - we generate errors for the whole test for the most part.
I have posted some video and screen shots of issues we are having - If any more information is need, please don't hesitate to ask - I will award full points to those who have the best answers for these issues.
