I have ran into some problems. I have my sdk client (remote to RMS) running for several times. Then I disconnected from the network before shutting down the client. Then everytime when I run the client again, it cause the ServerDisconnectedException

->The client has been disconnected from the server. Please call ManagementGroup.Reconnect() to reestablish the connection.

Through the stack trace, it points to this function:

ManagementGroup^ mg = gcnew ManagementGroup(host);

Question: How can I call reconnect without creating the ManagementGroup first?

How can I solve or get around the problem?

Thanks.

Steve

The client is completely shut down, and the first call to new ManagementGroup fails. No event log errors on either RMS or client computer. I reinstalled RMS (delete DB), and the problem still exists. There must be something cached ... Here is the complete Exception.

Line 780 is where I first call new  ManagementGroup

ServerDisconnectedException->The cl

ient has been disconnected from the server. Please call ManagementGroup.Reconnec

t() to reestablish the connection.

The UI Console generates the same exception.

I move my app to RMS, it runs ok there. There must be some cache on client computer.

Uninstall/reinstall UI console on this computer does not solve the problem.

Yes uninstall RMS, delete directory, delete db, reinstall.

Here is the exception from UI:

I am using the eval version of SCOM (MMS2007).

The exception says "this might be caused by a contract mismatch, a premature session shutdown or an internal server error." I believe "a premature session shutdown" is the reason. But how come it becomes to a fatal error? I will try to find another machine to install UI. But I believe it will run OK.

Hi,

We had the same problem. It turned out to be a corrupted DNS server in the environment that was causing an authentication failure.
