I have cluster SQL (2008) running under windows server 2008. The cluster is working file for both nods. The SQL server agent stop working. I got an error 1069 which is related to failure in login (I did not change the password for SQL or windows). I tried to reconfirm SQL password in SQL server manager but I got an error "The server threw an exception [0x80010105]". The SQL server service is working. However, the SQL server agent not working. The VIA protocol is disable.
