Configure domain users for Windows Services

This is a headache for Windows Service Permissions. I thought that local area network permissions were not a problem. As a result, no files could be copied and no directories were found. So I thought of configuring a domain user for the Windows service and a domain user with the right to access the LAN. When you enter the user@corp.com, the prompt "the specified domain does not exist, or cannot prompt", is it your own input error, so use the "Browse" next to let windows for me to query and generate this user name, I entered it myself. No matter whether you click "OK" or the above error is prompted.

Therefore, the service user is changed to "user", and the domain user is entered during installation, and the installation cannot be installed.

Back to the original idea, is it because domain users cannot use Windows Services? A user is added locally and configured to the service! I found that the entered user name was changed to ". \ User". Why did the user name go behind? Therefore, the format of the entered domain user is corp.com \ user, and click "OK". Hahaha also succeeded.

And later, he discussed with the network management, he said that the default format is the above, "\" format means inherited from the parent domain or something, not very familiar :). Finally, you can access the LAN as usual.
