Loss of domain

[tstrub]

Have run into an issue with our 5.5 esxi server in the past several days - it sporadically started not allowing administers to log in with their domain accounts. It appears that our Active Directory integration is broken.The problem has continued to get more and more acute and now, no admin access is possible without the local vsphere account. We have the domain set and it has SSO as the domain login option. I did go to the "users and groups" and attempted to edit one of the domain accounts and received a "Error: Idm client exception: Failed to establish server connection" message - what steps should I take to troubleshoot the AD connection issue?

Thanks for any advice you may be able to lend ...

Hi, have you checked if your DNS servers configured for the hosts and vcenter are up and running properly?

Hi, thanks for the reply. Yep, checked the dns records and the hosts are all set to the correct IPs. Using the local vsphere admin accounts, I can get in and see there are no alarms or other issues with the system.
