I service packed to SP3 and after a reboot, all users seem to login with cached credentials and then on the refresh it kicks the user out with an error stating the user source has a problem or the user has changed their password.

If I try and login as a user on a new workstation with the ZCM Agent newly installed I cannot login at all and comes up with the credentials are incorrect or there is a problem on the server certificate. How can I check my user source is actually working properly as the communication status is green.

I suspect that this problem is not just down to SP3 but the fact that this server had to be rebooted ( which has not been done for a long time) and now it has picked up a problem with the certificate.

I have done an update on the certificate from within user sources.

Please help
