After selecting "Switch Users" from the Ctrl+Alt+Del menu, I can no longer log back into my account, it errors with: "The referenced account is currently locked out and may not be logged on to." a glitch perhaps?

If the account is locked out, then you can recover by logging in as any other user that has Administrator permissions and unlocking the account. Do you have account security set to lock accounts after x number of bad passwords?Dave Bishop Senior Technical Writer Windows Server Networking User Assistance
