Posted: Mon Feb 14, 2005 3:41 pm    Post subject: Domain Issue Reply with quote

I have currently got a test setup with 3 2003 domains (A, B & C - all in
seperate forests).

Domain A is a resource domain, so it has a one way outgoing trust to both B
& C. There are

no other trusts configured.

Domain Admins in B & C setup their users with their appropriate permissions
on the file

server in Domain A.Everything works fine.

But this is the thing; when an admin in either Domain B or C uses an NT
client to configure

its users on the file share in domain A it can browse both domains B & C and
see all the

users accounts in both those domains. If they use a 2000/XP client they get
challenged.

I dont want the admins to be able to browse through another domain but there
own because it

is a security risk but I must allow NT clients on the domain.

What can I do with this netbios issue?

Thanks

What NetBIOS issue?
As I read your post

is expected behavior when

1. A is account domain, so accounts used in B and C
are defined there
and
2. They have logged into a machine in domain A

Hi,

Sorry I wasnt being clear. Say for example I log onto the PDC in an nt 4.0
domain (call it dom A)and I want to set a users permisison on a file server
in Dom B (resource domain) I can also browse all other accounts in domain C.
There are no trusts between A and C.

Now if I do the same thing from a 2000 machine in Dom C I cannot browse the
other domain A. What happens is that a challenge appears asking for a
username and password.

OK, I think I am with you now.
With the a,b,c as just redefined
b is resource domain, version unspecified
a is nt 4 domain
c is other domain, version unspecified, existence in
same forest as b, if applicable, is unspecified
b trusts a
b trusting c or using forest implicit trusts unspecified

situation
1. log into PDC of a, use ACL editor to manage setting
of files shared from b, and accounts of c are visible
however
2. log into a W2k of c, use ACL editor to manage settings
of files shared from b, and accounts of a are not visible
without satisfying an authentication prompt

Thinking through these it seems to me that you are right, that
case 1 is in error
1. even if b and c are in the same forest, when logged into
a the credentials of the account in use should be recognized
only by b (which trusts a), and attempts to add/browse
groups outside of a or b should present prompt for account
login
2. behavior makes sense

I have not seen this, have functioned in similar environments,
and, have not heard of this before. Sorry. There is not by
chance an accidental authentications due to same name/password
account existing ??
