disabled guest account still gets locked
Posted on 2014-01-24
sbs 2003. i have the default guest account disabled however, malicious bots try to authenticate with my smtp server using this guest account. after the defined number of failed attempts i get 539 account lockout events for the guest account in the event log. i don't understand why i get a lockout when the account is disabled.
i tried to duplicate this by loging onto my smtp server via telnet to port 25, ehlo, auth login command but the base64 that i use for "guest" (online decoder) results in a "guust" account login in the event log. i'm not sure what i'm doing wrong here but what i'm trying to figure out is why do i get an account lockout on a disabled account?
