[cifs-protocol] [REG:111051760827237] SMB_COM_NT_TRANSACT response with SetupCount != 0

[Volker Lendecke]

Hi!

Yep, thanks, that does it.

The display is considered broken however. The reason for
that is different though: The client does a trans2findfirst
in directory \@GMT-... which Windows responds to with
NT_STATUS_NO_SUCH_FILE. Samba in the case we tested returned
the stat info of the directory where the unix snapshot
lives. When we return NO_SUCH_FILE here as well, the
previous versions display looks like the attached
screenshot win2k8-win2k3.png. The broken one is
win2k8-samba.png.

Please close this particular case, we might open another one
asking for findfirst handling in VSS directories, but we
have to dig in the docs first a bit more.

Thanks,

Volker
