Re: Access denied on network share in an other domain



r14,
I don't think that's really what you would want to do.

Leaving aside the idea of the Trust for a moment, the idea is that hosts in the DMZ (which could be compromised) should have no or limited access to the LAN. Limited access would means specified ports to specified hosts. For example LDAP or Radius or SecurID.

For the DMZ to get be able to a Share on the internal network is probably not desirable.

It sounds as though what you would do is to copy out your data from the internal network to the DMZ. This requires no inbound traffic to be allowed. You could use FTP or Robocopy to do this. The copy needs to use credentials that the DMZ recognises, e.g a local account on the DMZ server, or else you can use a one way trust where DMZ servers trust internal server.
Hope that helps,
Anthony

thanks for the reply Anthony. As for now, I'm able to log in my internal
domain using dmz domain credential. This prove me that my trust work, but for
some reason, my web servers in my DMZ are unable to get on a share in my
internal network. I'm starting to believe I got this concept of trust all
wrong. Furthermore, how can the concept of pass-through authentification
worked without a trust between two domains?

What I'm trying to achieve with my DMZ is to be able to have web in a DMZ
using a single storage area located in a internal network. Is there other way
to do this?

thanks

Fred,
If the DMZ domain trusts the internal domain you can Push files out to it.
If the internal domain trusts the DMZ domain (not what you want), the dmz
can Pull files out from it.
Ideally you would want the DMZ to have no inbound access to the LAN, so you
would want to push files out to the DMZ.
