cannot connect to Teradata server

Hello TD experts!

My Teradata server is no longer accepting connections.

The first error is

NCR TDATA.DLL
10065 WSA E HostUnreach: The Teradata server can;t currently be reached over this network

I noticed that the recond service was down, but I can't start it

In System log of Event Viewer

The Teradata Channel IOCTL Driver service depends on the following nonexistent service: BtiApapi

Any ideas?

Thanks!
