Advapi is known as part of the Netdevil trojan/backdoor.
See: http://www.processlibrary.com/directory/files/advapi/
Scan all your workstations and servers with a good antivirus.
These are the manual removal instructions: http://www.exterminate-it.com/malpedia/remove-net-devil
Also, to be absolutely sure: if you find the advapi.exe or shellapi32.exe you can also have it scanned at virustotal. They use all virusscanners known to mankind at once;-)

It's prolly not what you fear. But to get rid of these messages you need to track this access attempt to its source process and fix it there - use the tools from Sysinternals Suite (http://google.com/search?q=sysinternals+suite). Apply logic: if it were malware trying to brute force its way in, it wouldn't be wise to start with anonymous but rather an Administrator, right?
maybe you unnecessarily run a ftp server (where anonymous is often used for public access).
