Here are a few things to try if client PCs can't access a CacheDrive over VPN by hostname:
- Some VPN setups do not allow NETBIOS broadcasting by default. Check your VPN hardware or software for options related to NETBIOS handling.
- If you're using DNS for name resolution, make sure that your client PC is using the correct DNS server.
- Open the port for mDNS (UDP/5353).
