ERRMSG:Remoting Exception Has Been Thrown By The Target Of An Invocation


Hosted Exchange Extension (HEE) shows following exception:
Remoting exception: Exception has been thrown by the target of an invocation

Applies To
MachPanel all versions
Hosted Exchange Extension (HEE)

This problem can occurs due to two reasons.
Firstly, when MachPanel remote Server is not installed at Exchange Server i.e. other than the server where MachPanel is installed. Or it is installed but the MachPanel Provisioning Service is not running.
Secondly, a firewall can block the port 7860 for MachPanel Provisioning Service disabling it to communicate properly.

Let us consider an example scenario for this which is as under:

Example Scenario

Server1: Active Directory (AD01)
Server2: Exchange Server 2007 SP1
Server3: MachPanel Control Server

This explanation is for above server setup scenario.

Case 1: Remote Server not installed or MachPanel Provisioning Service not running

Install MachPanel Remote Server
You need to install the MachPanel Remote Server on Exchange server and then configure it in MachPanel Control Center properly. Here Exchange server is Server2.
Please consult Exchange installation/configuration guides at:
Note: These settings are for Stand Alone Exchange Module of MachPanel.

Step2: Setup Active Directory Domains and Domain Administrator Login:
In your MachPanel Control Center login, Navigate to Home » Service Director » Active Directory Domains
    • Domain administrator login: This will be the user responsible for     connecting with Active Directory.
    • It is recommended that you create a new user “administrator2” and     call it the Domain Administrator Login.

Please refer to: for creation of administrator2 login for MachPanel.

Step3: Domain Administrator Login Permissions:
The Domain User (i.e administrator2) which is used for MachPanel should be member of certain groups for Standalone Exchange. For assigning related permissions please see

Step4: Configuring Hosted Exchange Extension (HEE)
In MachPanel Provider Control Center (PCC), navigate to:
Home » Service Director » Exchange Hosting » Server Groups » Edit Exchange Server

Set the following attributes:
  • Server alias: This should be complete server name e.g Complete name of Server2 with Domain Name.
  • IP: This should be IP of Server2. This same IP has to be in registry of remote server. To ensure this, follow these steps:
    • Click Start >> Run
    • Type regedit
    • navigate to HKEY_LOCAL_MACHINE\SOFTWARE\MachSol\MachPanel
    • Ensure that the string RemoteServerPublicIP is set to the same IP address as for Server2. If not, please make it same here
  • Server Name: This should be complete server name like
Step5: Set MachPanel Remote Service identity
  • Update identity of MachPanel Provisioning Service. i.e. Server2 in this scenario. For this, follow these steps:
    • Click Start >> Run
    • Type services.msc
    • Microsoft Windows Services screen will pop up
    • Double Click on MachPanel Provisioning Service
    • Select Log On tab
    • Click Browse and Select the Domain Administrator Login (from Step3) from Active Directory Users
    • Set Password of user.
Restart MachPanel Provisioning Service

  • Click Start >> Run
  • Type services.msc
  • Microsoft Windows Services screen will pop up
  • Double Click on MachPanel Provisioning Service and click Start
Alternatively, you can also start and stop MachPanel Services using Configuration Studio. For example, to start MachPanel Provisioning Service, please open Configuration Studio and go to Configure >> Services and click Start All Services button. Similarly for stopping all services click Stop All Services button
