Bad login alerts

Hi all
If someone tries an ussuccesful RDP attempt on server much helpful info is
recorded, especially IP address.
Seeing some login alerts of the below where limited info is recorded.. Its
this NtLMSsp logon process

Logon Failure:
Reason: Unknown user name or bad password
User Name: DOC-MAIL$
Domain: DOC
Logon Type: 3
Logon Process: NtLmSsp
Authentication Package: NTLM
Workstation Name: DOC-MAIL
Caller User Name: -
Caller Domain: -
Caller Logon ID: -
Caller Process ID: -
Transited Services: -
Source Network Address: -
Source Port: -

Username / Domain and workstation name have no relation to site where server
recorded this.

I thought it maybe an RWW attempt but this gives:-
Logon Failure:
Reason: Unknown user name or bad password
User Name: aaaaaaaaa
Domain: SERVER
Logon Type: 3
Logon Process: Advapi
Authentication Package: Negotiate
Workstation Name: SERVER
Caller User Name: IUSR_SERVER

TIA, have a great day / night depending wherever you are... ;-)
