We've been using CBFS3 under Windows 8 mounting a network drive which has been working fine, however running the app on 8.1 shows it as a disconnected network drive.
Is this something that has been fixed in CBFS4 or 5? And if so is the fix in the network redirector module that we could easily back port?

Yes, IIRC there were some updates made. They are not fixes, as Windows 8 and 8.1 break some things and we needed to write additional code for their support. So it's time to upgrade.

You have a license for version 5 and you will find your new license keys and downloads in My Control Center. Source code will be available upon release though.

Sincerely yours

I've updated to CBFS5 however the problem still remains. In fact after the update a windows 8 (not 8.1) that was not exhibiting the problem is now also showing as a disconnected network drive.
I am installing everything using the helper dlls included the network redirector. What more can I do to diagnose this?

Please use GetModuleStatus() method to check that the DLL is installed. If GetModuleStatus() returns positive result, you will need to take Process Explorer from sysinternals and use it to see, what DLLs are actually loaded to Explorer process (search by name in Process Explorer). CbFsNetRdr5.dll should be among the loaded DLLs.

Also the problem can be because your application that calls AddMountingPoint is run elevated (i.e. "run as administrator"). In this case the mounting point is created in the special separated session (for elevated programs) and Explorer doesn't show it correctly. In order to correct it either run the app non-elevated or pass a non-null value as the AuthenticationId parameter to the AddMountingPoint call.

Looks like an issue when updating our installer and the network redirector was getting missed. This all appears to work now and does fix the issue with 8.1 we were seeing

Turns out this wasn't an issue with CbFs at all so putting the info here in case anyone else hits this problem.

During the update from Windows 8 to 8.1, a registry key gets replaced which stops the network redirector from being loaded. The fix (other than reinstalling the dll) is to update:
HKLM\System\CurrentControlSet\Control\NetworkProvider\Order and edit ProviderOrder to include the correct version of cbfs at the front.
Eg. Change it from:
