>>>You are aware of the SMB2 issue with VFP, Access and other ISAM file-based databases? It will likely never be fixed. See the thread http://www.levelextreme.com/DataEntryThreadView.aspx?ID=1430067
>>>
>>>Also, Michel Fournier, the owner/operator of the UT, found that the latest available VFP OLEDB provider is not reliable under load. After much back-and-forth with MS, that's another issue that will not be fixed. Arguably, this shouldn't be too much of a problem because OLEDB is being deprecated by MS. But, the situation with ODBC is even worse, the latest driver only supports VFP6, and none of the data/database changes made since then are supported.
>>>
>>>Interop with 64-bit apps is challenging. Might not be a big problem now but it'll only get worse.
>>>
>>>MS is not so much actively trying to kill file-based databases, instead it's neglect and/or lack of testing. SMB3 is coming out in Windows 8/Server 2012, both are still in RC. I don't know if anyone has set up an environment with these OSs for testing but chances are the community is going to have to do it, because MS probably won't.

>>MSKB articles describing the SMB2 issue with Access and FoxPro:

>>ISTR Brandon Harker spent a lot of time on an elevated tech support incident with MS. I believe the hotfix referenced in KB935366 was tested and found to not fix the issue (at least with VFP, I don't know about Access).

>But please do not feed into all of this paranoia that there will be a problem with VFP (as refuted above by your initial references, no less). Microsoft is not trying to kill file-based dbfs and it is REALLY ridiculous to think so! Also, it is highly unlikely this will be a problem by accident since SO MANY would be adversely affected (not just foxpro!) - which MICROSOFT DOES CARE ABOUT.

The first reference (KB935366) talks about a hotfix, but that hotfix was tested and it does NOT fix the problem with VFP running on SMB2. This is a real problem that people are having to deal with, whether you want to believe it or not.
