Anonymous Logon. Is This A Security Risk?

Hello
After having done the complete Malware removal process with the help of Kestrel13. Looking at the security event log i still see this anonymous logon each time i turn on the computer. According to the log its been on there for a long time. Should i be concerned with this, or is it some type of standard procedure. I'm running WinXP SP3 Here is the info it shows for the logon.
User: NT AUTHORITY\ANONYMOUS LOGON
Successful Network Logon
User Name:
Domain:
Logon ID: (0x0,0x1245E)
Logon Type: 3
Logon Process: NtLmSsp
Authentication Package: NTLM
Workstation Name:
Logon GUID:

 

It might be fine...


From what little info you gave, it seems to me that it might be a local service or process that is running. Was there an IP address or anything listed? Is there an event ID number? Post more details if you can.

 

Only an Event ID: 540
I'm not exactly sure how to do most of this, but i sort of know how to get around on this computer. with that being said
Looking into Microsoft's description of the Logon Type: 3 it says a type 3 is a logon from a remote location on the network.
I don't see any details as far as a IP Address or program name, but i also don't know if there is another way to lookup that info.

:confused
