Cannot write Windows file with error 22

[nikolay.semov_]

After upgrading from Windows Server 2008 R2 to Windows Server 2012 R2, the SA displays error upon upload and creates 0-byte files, albeit with the correct name.

The logs show this:

Cannot write Windows file filename to \\server\share\folder with error 22.

Does anyone know what error 22 is or how to find out? Thanks.

I think it is a read/write error.
Which version of the IVE OS are you using? I know there has been a reported issue with file shares on Server 2012 that has been fixed in the latest 7.4 and 8.0 builds
