NT acessing XPProSP2 share

Hi,

Having problem on a mix NT/XP network. I recently installed a new
machine on the network with wxpprosp2.

I've created a share and configured it for everyone read/write. From
other xp machine I can acess this one, as from it I can acess any
shares on machines in the network (including NT machines). The problem
is when I try to acess this xp share from NT machines. I get the
following msg:

"the user has not been granted the requested logon type..."

Allready search in the groups and got some reports related to the
security policy , witch I allready configure to allow any kind of acess
from everyone. Also the guest account is enabled.

None of this as make the trick for me. Anyone?

Best regards,
