What is the analogue of Teamviewer among free software for working without access to the Internet?

Question

Computer networks

There is a closed large distributed network, without access to the Internet (security requirements). Policies prohibit remote connection to a computer for people, the user does not have the right to change this setting himself. But sometimes you still need a remote connection for technical specialists to provide assistance. Teamviewer, amiadmin, etc. require internet. I'm interested in free programs that I can send to the user so that he starts and I can connect with full functionality (viewing user actions, transferring files, controlling the mouse and keyboard).

Answer 1

In general, private networks use RDP.
If you need to interact with the user, then remote assistance, Teamviewer, VNC-based builds, and more.

Answer 2

"But sometimes you still need a remote connection for technicians to provide assistance."
If you are a "technical specialist" of an outside company, then why on earth should you be given remote access to a user's computer inside the corporate network?
If the user cannot do what is needed, let him call his technician who will talk to you.
If your program has so many problems that they need to be solved on the user's computer, you are probably doing something wrong.
