Hello, we have just wrapped up a SBS 03 to 11 migration, or so we thought. Everything was working well for about 2 weeks, then we went through the migration wizard on 11 and finished it and then demoted / removed exchange from 03. After we removed exchange and DC from 03 and rebooted we started to have issues with Exchange on the 11 server about half an hour later.
No one is able to connect to the exchange server via their Outlook and OWA. Now, I was working remotely and somehow lost connection to the server; therefore please note that I do not have the entire info, but will try and jot down what I remember.
1. When I log into 11 and try to start up EMC, I get an error indicating "he attempt to connect to http://servername.domain/powershell
using "Kerberos" authentication failed:"
2. In the Application event logs, i remember seeing an Exchange error ID 9106 (forgot exact error as I wasnt able to write it down before I lost remote access)
these are the errors I remember seeing before I randomly lost remote access. This all happened after I demoted and removed DC/Exchange from old 03 server. I was thinking maybe there was a DNS and/or issue with the migration but am not positive. I will try and get into the office early tomorrow and look around for more info but was hoping to see if anyone has any ideas...please let me know, thanks
