We are not able to use the Admin Console to manage our shared databases. The actual sharing is working perfectly.
We can log onto the server console and access any of the settings under Configuration.
However when we select Clients, Databases, Schedules or Statistics the data is displayed correctly but immediately we get "Admin Server Connection Error: An unknown error has occurred." On "OK" the console closes.
We have upgraded to server 9.0.3.326. The server is on a windows server which according to our IT support is "running Windows Server 2003 R2, Service Pack 2 (and fully patched with all MS patches prior to SP2). The installed version of Java is Java 6, Update 3 – this officially reports from the Control Panel as 1.6.0 (build 1.6.0_03-b05)."
