I have a 2003 multihomed server. It is also a 2nd DNS backup server. Every week or so I receive an Event ID 1097: Windows cannot find the machine account. The Local security Authority cannot be contacted. in the event log. I have to use the netdom resetpwd command and reset the account pw for the dc , then reboot in order for the server to come back up without errors. The time is correct on all 4 DC in the domain. Net logon is started on all 4 DC. All 4 dc have 2 nic cards for access to the 2 networks and FSMO roles. When the error occurs the applications on the server are not accessible for users. Does anyone know what I can check in order to keep this DC on the network?
