this also appears when the Win2K machine sends
call_trans2qfilepathinfo: TRANSACT2_QPATHINFO, the msdfs code finds
the correct file, and decides it is an msdfs link, then we get the
following:

[2002/05/09 18:05:55, 3] msdfs/msdfs.c:(313)
  dfs_redirect: Redirecting \vdisktest\SWP\Output_Renders\caa_007_tk1
[2002/05/09 18:05:55, 3] smbd/error.c:(106)
  error packet at msdfs/msdfs.c(662) cmd=50 (SMBtrans2)
NT_STATUS_PATH_NOT_COVERED

which results from:

#define RESOLVE_DFSPATH(name, conn, inbuf, outbuf)              \
{ if ((SVAL(inbuf,smb_flg2) & FLAGS2_DFS_PATHNAMES) &&          \
      lp_host_msdfs() && lp_msdfs_root(SNUM(conn)) &&           \
      dfs_redirect(name,conn,False))                            \
             return(dfs_path_error(inbuf,outbuf)); }

key bit being from dfs_redirect:

	if (resolve_dfs_path(pathname, &dp, conn, findfirst_flag,
			     NULL, NULL, NULL, NULL)) {
		DEBUG(3,("dfs_redirect: Redirecting %s\n", pathname));
		return True;
	} else {

This bit returns true which causes the error, I just havn't worked
what this has to do with the '%S' error or if this is a red herring.

This I think needs to be fixed so that resolve_dfs_path()

	/* check if need to redirect */
	fstrcpy(localpath, conn->connectpath);
	fstrcat(localpath, "/");
	fstrcat(localpath, dp->reqpath);

	/* Need to substitute macros here ? */

before the call to is_msdfs_link()

Am I on the right track here ?

Thanks
