FTV: “ computer X does not exist in the factory talk view directory.”

I am having a problem with Factory talk View Administrator. Each time I try to contact to me project via (communication setup inside ftv) or open my project it states: “ computer X does not exist in the factory talk view directory.” How can I fix this fast?

Probably it's a problem with RSLinx Enterprise:

TN 714498 RSLinx Enterprise error: Computer does not exist in the FactoryTalk Directory (Access Level Everyone)
