Detailed explanation of solutions for WMI RPC server unavailability

This article introduces a detailed solution to the unavailability of WMI RPC servers. I will share it with you, as follows:

ConnectionOptions connectionOptions = new ConnectionOptions();
  = userName;
  = password;
 ManagementScope managementScope = new ManagementScope("\\\\" + host + "\\root\\cimv2", connectionOptions);
 try
 {
  ();
 }
 catch
 {
 }

Solutions for "RPC server is unavailable" or other situations where it cannot be connected (make sure there is no problem connecting to this machine):

1 Check whether the remote servers "Remote Procedure Call", "DCOM Server Process Launcher" and "DHCP Client" services are enabled

2  Check the remote server Local security policy - Local policy - Security options - Network access: Local account sharing and security mode - Properties Select: Classic - Local users authenticate with their own identity

3  On the remote server, run "netsh firewall set service RemoteAdmin".

The above is all the content of this article. I hope it will be helpful to everyone's study and I hope everyone will support me more.
