Hi all, and sorry about my little english, i will try to be as much clear as possible. Recently we wanted to test a newest Echo series, but we get this issue with Managent Console that comes with this Echo series: Older Agents can not connect with newest MC. We must update to newest Agents. Well not a problem and understandable. We update one Oldest Agent to begin the test, although the update was successfully, the newest MC hungs up when trying to connect to newest Agent. Nothing happen when connect to newest Agent, only hour glass still twisting in the screen. The only way is to kill the task with task manager. Connection links seems goes fine, MC can browse clients, if You choose an old one, You get an error. If You put wrong credentials (username/password), You get another error. But nothing happen when connect to newest Agents. Oldest MC that comes with True Image Enterprise Server v9.1 can connect to newest Agents without any problem. And ofcourse, can connect perfectly with oldest Agents also. We are missing something ? Is the Echo series a must upgrade we need to take into acount? Thanks in advance.
