While I know it is technically possible, what are the postive/negatives of
sharing a commnon physical LAN on multiple domains.
I have a company that wants to build a second domain onto an existing
address space, 172.19.10.0/24. The assigned and reserved address would be a
mixture from top to bottom.
I read where there are potential authentication problems with the computers
if this infrastructure is built this way.
Looking for advice whether to proceed.

What is the reason they want to do this?

There seems to be some concern about multicast resources that exist in old
domain 1 not rendering properly into new domain 2. So the wizards of smart
want to move domain 2 into the same address space as domain 1. I am seeking
advice of the pros and cons before I finalize my response to them.

Besides DNS and DHCP that should be your concerns, note that within a
common subnet, you won't be able to have dublicate machine names. I've
had that once with a customer. They basically tried to promote a new
domain with a domain controller called "dc1" which basically had the
same name than an already promoted DC of another domain in the same
subnet. NetBIOS names must be unique.

Cheers,
Florian
