I've now tested on all Windows platforms. Passing NameUnknown returns
ERROR_NONE_MAPPED if the current user is a local (non-domain) account and
ERROR_NO_SUCH_USER if the current user is a domain account.
The ERROR_NONE_MAPPED code is returned for all formats except
NameSamCompatible if the current user is a local account.

Based on my new test runs, I came up with the following test:

  ok(rc ||
     (formats[i] == NameUnknown &&
      GetLastError() == ERROR_NO_SUCH_USER) ||
     GetLastError() == ERROR_NONE_MAPPED ||
     broken(formats[i] == NameDnsDomain &&
            GetLastError() == ERROR_INVALID_PARAMETER),
     "GetUserNameExW(%d) failed: %d\n",
     formats[i], GetLastError());

This passes on all my Windows machines. Personally, I probably wouldn't have
used broken() for the W2K case but I'll follow your lead :-)
