Hi, I currently installed new exchange server on my DRC site, I have exchange server 2016 on my DC and exchange server 2019 on my DRC.

the problem is, my exchange server on DC site (2016) cannot communicate through Windows to exchange server on DRC site (2019), I tested with "get-wmiobject win32_computersystem -computername" and it's showing error message = "Management Instrumentation (WMI) with error : WMI exception occurred on Server ' ' : access is denied (Exception from HRESULT:0x80070005(EACCESSDENIED))".

But when I tried tested the same script from exchange server DRC Site (2019) to exchange server DC Site (2016), it resolved.

I've tried to checked the permission and firewall and match with all server, but the error is still showing.

    It seems like there may be some issues with permissions or firewall settings preventing the communication between the Exchange servers. Here are a few things you can try:

    1. Make sure that the appropriate firewall ports are open between the two sites. Exchange uses several ports for communication, so you may need to open multiple ports. Microsoft provides a list of the required ports for Exchange Server here: https://docs.microsoft.com/en-us/exchange/plan-and-deploy/deploy-new-installations/firewall-ports
    2. Check the permissions on the Exchange servers. Make sure that the accounts you are using to run the scripts have the appropriate permissions to access WMI on both servers. You may need to add the accounts to the local Administrators group on both servers.
    3. Make sure that both servers are running the same version of PowerShell. If one server is running an older version of PowerShell, it may not be able to communicate with the newer server.
    4. Try running the PowerShell script with elevated privileges. Right-click on PowerShell and select "Run as administrator" before running the script.
    5. Check the Event Viewer on both servers for any error messages related to WMI or PowerShell. These may provide additional information about the cause of the issue.

    I hope these suggestions help you resolve the issue.

    Hi @ Ardan Zaki ，

    Please refer to the following steps to compare whether the permissions of the two servers are the same：

    1. Enter Dcomcnfg in the search box in the lower left corner to open Component services.
    2. Right-click My Computer > Properties. Under COM Security, click Edit Restrictions for both sections.
    3. Check whether remote access, remote launch, and remote activation are provided for Users.

    In addition , in my tests, when I remove the permissions related to the Administrators Group, I get a similar error when using the get-winobject command in DC:

    Hope the above suggestions are helpful to you!
