Hello
By chance I discovered that every 2 minutes there is a login failure on my standalone (Workgroup) W2K8 R2 Server.
The administrator is disabled (login errors also appear when administrator user is enabled).
Could not find any tasks that are running with administrator credentials. It seems to me that it must be from the same machine, as the source IP Address is 127.0.0.1.
Does anyone have an idea?
Here the log:
