Log on to the gateway server to be removed with the Operations Manager 2007 R2 Administrators credentials.
In Control Panel, in Programs and Features, right-click System Center Operations Manager 2007 R2 Gateway, and then click Uninstall.
To remove a gateway from the management group
On the management server that was targeted during the gateway server installation, log on with Operations Manager Administrators credentials.
Open a Command Prompt window, and browse to the directory to where you copied Microsoft.EnterpriseManagement.gatewayApprovalTool.exe.
At the command prompt, run the following command, where GatewayName is the name of the gateway that you want to remove. Microsoft.EnterpriseManagement.gatewayApprovalTool.exe /ManagementServerName=<managementserverFQDN> /GatewayName=<GatewayFQDN> /Action=Delete
Open the Operations console to the Monitoring view. Select the Discovered Inventory view to see that the gateway server is no longer present.
