Admin account worked fine on Monday. The kid used her (non-admin) account in the meantime. Now it won't log into the admin account - "The User Profile Service failed the logon. User profile cannot be loaded." I've read a few other boards on this issue, so I am now doing a thorough virus scan and will include results as soon as they're available. But I am not confident about moving forward with any of the paths I've seen laid out, and some of them don't apply if you can't access the admin account anyway, so I wanted to start a thread here (I've gotten fabulous help here several times before). It's running Vista Home Premium SP2. AVG 2013 Internet Security. Can't think what other specs may be relevant, but am happy to provide whatever would be of use. Thanks!!
