Muiltiple users on the same PC at the same time.

Hello folks. This is my first time here. I have a question regarding our company’s IT usabilities. I wanted to find out if there is a program or way in windoes (freeware or to buy) that will allow multiple users to login into the same PC at the same time remotely. For example, I have a PC which acts like a server. Can 10 people loginto the same server using programs like “GotomyPC” and work off it simultaneously??
Thanks for your inputs in advance.
Peter.
