hello, i have a sql 2005 instance in a two node cluster. the instance has mixed authentication, suddenly i started having erros with windows accounts trying to connect to server and i couldn't connect to server myself using my windows account. Seems like sql logins can connect; however i don't have a sql login with sa rights. I attempted to reboot my server and now my instance cannot get online, sql browser is up however my sql service and sql agent keeps failing with the below error:
Login failed for user "windows account"
can someone please tell me what should i check for?
