How to Connect to an SDK Service by Using the Current Credentials

Applies To: Operations Manager 2007 R2, Operations Manager 2007 SP1, System Center Operations Manager 2007

An Operations Manager SDK client application can connect to the SDK Service by using the credentials of the current user.

Example

The following example demonstrates how to connect to an SDK Service by using the credentials of the current user. The example also shows how to handle some common connection failures.

Instead of explicitly calling the Connect method, you can also instantiate a new ManagementGroup object by using the new keyword, as shown in the following example.

mg = new ManagementGroup(serverName);

Is the same as:

mg = ManagementGroup.Connect(serverName);
