>I've been using mapped drives, NetBIOS-style UNC addresses and IPv4-style addresses for many years and know they can usually be made to work. An IPv4 address and an FQDN are only the same if DNS is available to resolve the name *and* VFP tries to resolve it in the first place. I didn't know VFP does try to resolve FQDNs, that's good to know.

Yes of course - if DNS is not available you're not likely to have a path to any server you're trying to connect to :-)

All of this has nothing to do with FoxPro though, as Fox just passes the paths on to Windows for processing - so it's all in the Windows configuration that's responsible for this.

It works, but there are many things that can trip this up which is why I would not ever recommend building a production solution over internet mapped drives - it's just too flakey and slow. Internal network addresses (WAN) are another story - same issues but somewhat mitigated by the proximity and lack of latency.
