Goodday
I have a dell optiplex gx280 with windows xp, office 2003, internet access. Problem is everytime user send mail from outlook-his account gets lockout, he can read mail but when replying or sending new messages his account gets locked out, Checked eventviewer-this event is showing at the time the account locked. 4-6 entries for just that day when account locked a day(4-6 times)
Source: LSasrv
Category: SPNEGO (Negotiator)
Event Id: 40960
The Security System detected an attempted downgrade attack for server exchangeAB/tsahex01.corp.timken.com. The failure code from authentication protocol Kerberos was "The user account has been automatically locked because too many invalid logon attempts or password change attempts have been requested.
(0xc0000234)".
What can i do to fix this??
