I had a job running under non-SysAdmin job step proxy account. This account has 'system administration' right and also a domain user account.
This job has been running so many months without any problem until now. There is no change on the server recently. Can someone tell me how to fix this problem: The following is the error message I got:

================================================== ======
A problem occurred while attempting to logon as the Windows user 'SQLAgentCmdExec': Logon failure: the user has not been granted the requested logon type at this computer. The step failed.
