Hi all: Has anyone any idea what SingleSignOnTools is or does? It seems to be constantly polling something in order to connect but I can't see exactly what is happening It does produce its own log with the constant msg: kdcmond cannot retreive the computer's local Hostname , retrying .. Looking in Activity Monitor kdcmond has a process id of 5975 and runs as root. Any ideas? Chris G5 10.5.7 4 Gb Ram
