Security log details.....Logon

Here is a message i have under event viewer under the security tab under logon 4625

Can someone tell me exactly...in detail...as to what i am looking at....I am assuming that the administrator tried to login remotely to a computer system...

But the system that is showing up...is that the system they was trying to log into or was that the system they was on?????

An account failed to log on.
