There was [an unnamed] problem connecting to the server
- Why doesn't that message give more information, even if via a link?
- the server is on my LAN and is pingable
- the Linux server is exporting a CIFS/SMB file system visible elsewhere. It is available despite:
"The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
Ping works, either to the IP address or to the name in the /etc/hosts file.
