Security Log

Hi All,

In the Event Viewer’s Security Log I have some disturbing events. An example: I logged on to the server succesfully, so a successfull audit was registered in the Security Log. After being busy on this server for a while, I decided to check whether new events were logged in the Security Log. To my surprise a new event was logged with following details: account name = password, workstation = xyz. The account name does not exists on the domnain! The computer mentioned indeed is my computer from which I have made a connection to the server. This is not the only event with those strange non-existing account names. Who can tell me what is the matter?
