my server error log is reporting that almost every single minute there is a failure audit below is the info in the message

Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. [CLIENT: x.x.x.x.]

I'm not sure how to fix this error - or even find out what is trying to login - does anyone know how i can troubleshoot this error?

Are you using IIS on this server? If so, then you need to either change the IIS Predefined Security Account in DefaultAppPool to Local System, or adding the user to SQL and giving it rights to the databases your web server apps use.

Yes I'm using IIS will changing it to local system effect anything else on the server?

I just want to know how (or if) this will effect anything else, thanks for your help!

it looks like a very big security issue to change it to the Local system - can you explain how to add the user to SQL and giving it rights?
