# Changing Endpoint Central Server's Name/IP/Port Details in Agent

## Problem

Agents not communicating with the server after migration.

## Cause

The new server details like FQDN, IP, Port numbers are not available with the agent.

## Resolution

Changing the following details in the Endpoint Central Agents:

- The Name or the IP Address of the Endpoint Central Server
- The HTTP and HTTPS ports that are used by the Endpoint Central Agents to communicate with the Server
- The mode of the communication as HTTP or HTTPS

To change the values, either a GPO or a cscript can be used. This page explains about creating a GPO to change the server contact details in agents.

GPO can only be used in a Windows environment. [To change details in Mac and Linux machines or to execute a cscript (for Windows), follow the steps in this page](https://www.manageengine.com/products/desktop-central/desktop_agent_change_ip.html).

## Steps

1. To get the updated server details, go to the product console, navigate to **Reports-->Query Reports-->New Query Report** and execute the following query:

   ```
   SELECT
   SERVER_MAC_NAME,SERVER_MAC_IPADDR,SERVER_FQDN,SERVER_PORT,HTTPS_PORT FROM DCServerInfo
   ```

2. The report will have the following details:  
   **<DCServerName> <DCServer IP Address> <DCServer HTTP port> <DCServer HTTPS Port>**  
   Copy the details and have it saved.

3. Also make a note of the mode of communication (HTTP or HTTPS) from: **Admin-->Security Settings**

4. Copy the [configureDCAgentServerCommunication.txt](https://www.manageengine.com/products/desktop-central/configureDCAgentServerCommunication.txt) file, save it as **configureDCAgentServerCommunication.vbs**.

5. Download [GPO_AgentServerComm.txt](https://www.manageengine.com/products/desktop-central/gpo-agent-server-comm.txt), rename it as **GPO_AgentServerComm.ps1** and save it in the same location where configDCAgentServerCommunication.vbs is saved.

6. Run **Windows PowerShell** in administrative mode and navigate to the location where the script is present and execute the script **GPO_AgentServerComm.ps1** with arguments as mentioned below:

   ```
   GPO_AgentServerComm.ps1 configDCAgentServerCommunication.vbs
   <DCServerName> <DCServer IP Address> <DCServer HTTP port> <DCServer HTTPS Port> <DCServerAgent Comm Protocol>
   ```

   Example:

   ```
   GPO_AgentServerComm.ps1 configDCAgentServerCommunication.vbs
   DC-COMP.DC.COM 192.192.192.192 8020 8383 https
   ```

7. In the PowerShell window, enter the **name** of the GPO to be created and press **Enter**.

8. Now, enter the **Distinguished Name of the OU or Domain** to which the policy is being linked.

9. Follow the steps mentioned below to get the Distinguished Name:

   - **Open Active Directory Users and Computers** in **Administrative Tools**.
   - **Right click** on the OU / Domain that needs to be linked.
   - Select **Properties-->Attribute Editor-->distinguishedName-->View**.
   - **Copy and paste** the value of **distinguishedName** in the PowerShell window and hit **Enter**.

10. If you want to **Add** another Domain, press **y** and add the required domain. Press **n** once all the required domains have been added. This will automatically initiate the application of the GPO.
