When we upgraded someone to Notes 6.0.2 CF2 from notes 5.0.11 we had the following message: “Non valid cross certificate for /Lotus. Public key does not match. Problem is either from corrupted cross certificate or from an attack. Please contact your Admin.” (sorry for the translation, it was actually a french error message). If you click OK several time, sometime you can get rid of it… but sometimes you can’t get rid of and need to kill/restart notes. We are planning to migrate all our users here at IBM Bromont so this error message is quite a concern. Thanks, Simon
