i thought it would be useful incase someone had this problem and searched the forums....what solved it for me was following these instructions:
Start>Run>Regedit>Hkey_Local_Machine>System>Current Control set>Control>Lsa. Now open the lsa folder... check the"restrict anonymous" file, NOT NOT NOT the "restrict anonymoussam" file. Make sure the Restrict Anonymous file value is set to zero

and not one(1). If the value is set to one(1) change it to zero
