Hi Yassine, How your DNS is configured? Whether the server is multihomed? Multihomed DC's always create DNS issues. And also have a look at ACE's article. Multihomed DCs with DNS, RRAS, and/or PPPoE adapters http://msmvps.com/blogs/acefekay/archive/2009/08/17/multihomed-dcs-with-dns-rras-and-or-pppoe-adapters.aspx Regards, Rafic If you found this post helpful, please give it a "Helpful" vote.
