Re: Best solution for email groups across 2 domains?

[Leif Pedersen [MVP]]

Hi,

You can have distribution groups spanning several domains in the same
forest. Try with a universal distribution group (or a universal security
group if the groups are also used for permissions) and you see

Thanks for the reply.

The problem with that is when you have a group called Managers in Domain A
that is Universal.....

You can add users fro any domain yes - that is good.
But when you look at the member of tab of the added user in domain B it does
not show he is a member of that group?
It is very hard to keep track like this?

Hi,

That is the advantage of universal groups - they don't replicate their
memberships to global catalog servers and therefore keeps GC replication
down. You can either create local groups and add these to the universal
groups or use global groups.

So you would suggest i use Universal Groups all the time then?

What about if a User in Domain A and a user in Domain B need to be part of
the same group(held in DomainA). What groups should be used then?

Thanks
Michael.

(Global groups have caused me rare problems with them not getting past the
categorizor so i am keen to avoid them).

Ummm . . . groups with a Universal scope do exactly that. Did you
mean Global group scope? Global groups don't put their membership into
a GC.

The description of the problem sounds like the group isn't a Universal
group. Becasue the "Member of" tab isn't showing the user as a member,
the possibility exists that there are two similarly named groups.

If the groups are mail-enabled and you expect them to work no matter
who uses them or where they're used, yes.

Universal scope.

>(Global groups have caused me rare problems with them not getting past the

They ger past the categorizer just fine, but a group with a Global
scope has an empty member list in every domain's GC except the domain
in which the group resides.
