Audit Failure - Security Concern????
Hello Guys and Gals,
On my Terminal Server I have been getting this error. And its weird, because it shows up for 30minutes straight and then disappears for another day or so. It is always from a different IP address. My server does not have any extra ports open, just the essential ports. It is also located behind a firewall and is kept up to date.
Below I copied the error message. I did change some identification to keep it secure.
An account failed to log on.

The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.

Any light on this issue to help me resolve this would be greatly appreciated.
