samba - Sep 2007 - Problem while accessing DFS links.

Hi All ,

I am trying to navigate the DFS links, but getting the following error.

cli_negprot: SMB signing is mandatory and we have disabled it.
protocol negotiation failed
Couldn't resolve \sal1

where sal1 is the DFS link created under STAND ALONE ROOT.

Could any one of you please help me to get rid of this error ?

Thanks and Regards,
