What is 'NT AUTHORITY\ANONYMOUS LOGON' every 15 secs


Recommended Posts

I'm a part-time admin on Server 2003.

 

Event Viewer/Security events 538/540 every 15 seconds I get an entry in the

log.

'Success Audit....Logon/Logoff....ANONYMOUS LOGON.....'.

 

Can I stop this - is it wise - maybe just not show these events?

Hi Thomas,

 

Does the server happen to be running IIS (Web services)? If so, IIS (by

default I believe), uses this account for serving up web page requests.

No it's not just because your an admin server.. Because i am a

normal home user and i get the same thing.... when i first saw

it, i thought i was being hacked. just recently windows showed me a

poppup that said something like. (there is a I.P. address

confliction within your network).

 

 

i don't know what it is or even if these 2 situations relate..

 

Any help would be appreciated.
