I have upgraded our ESM server from v3 to 4.1 today, uninstalled the previous version and installed the new version. Some of the Endpoint Clients are able to login ok, but others are getting a message that there is no Management Service available.

I have used the same certificate in IIS for the server install as this is the one that has gone out to the Endpoint Clients.

I am using eDirectory for the authentication, and have addded and completed all the directory configuration.

Any ideas?
