I'm running ZAM 7.5 IR 13. We have about 20 people who use it on a regular basis. However, today no one can log in - either to the web cosole or the manager. The error is 'Invalid credentials' on the web console and 'Unable to log on, please check username and password' on the Manager. All the services come up fine, but it's giving everyone that message. We're using a local SQL 2000 install. Thank you.
