#ifdef SUPERSERVER
const ULONG SERVER_CAPABILITIES = REMOTE_HOP_SUPPORT | MULTI_CLIENT_SUPPORT
| SERVER_CONFIG_SUPPORT;
# ifdef WIN_NT
const ULONG SERVER_CAPABILITIES_FLAG = SERVER_CAPABILITIES |
QUOTED_FILENAME_SUPPORT;
# else
const ULONG SERVER_CAPABILITIES_FLAG = SERVER_CAPABILITIES |

The SERVER_CAPABILITIES_FLAG value is returned via the mentioned SvcAPI
request item.

AFAIU, it was implemented to suit the server manager needs and it isn't
documented for public. But it's more or less the thing we're talking about.
