This is the exact text of the error message I get in VFP. I agree these are VFP messages but if it sheds light on the same
Error #: 1526
Message: Connectivity error: Unable to complete network request to host "DEVE2".
Failed to locate host machine.
The specified name was not found in the hosts file or Domain Name Services.
Line #: 835
Method: opentables
Object: vso3

In any case let us assume networking problem then why would it works fine using ODBC on the same network?

Please advise.
