Possible to share server’s GPU with PCs in the local network and office?

Someone has asked me and I did search but got both No, it can't be done and Yes, it can be done answers.

The scenario is: There’s a server with GPU (I don’t know its model and name) in an office, and there are some employees with PCs running a high graphics-consuming application.

The manager wants to see if it’s possible to share the GPU of server over LAN with PCs, so they all can have more graphics to use.

Is that possible? Is that reasonable?
