Overlapping AD Subnet Boundarieshello,
just to stop the troll...
Do you understand my others post about your network ?
Is you DC set up on its network interface with a 255.255.0.0 netmask ?
Your setup will work fine from an AD point of view (dssite.msc) , but not an IP
routing point of view if

I think that someone knowing this wouldn't have post the question.
I don't agree with this part. A lot of people don't think you can supernet
AD subnets. In fact I have had people tell me outright it is impossible to
do

In my opinion, there is a pure TCP/IP network issue...
A sample example:
The DC is 10.10.0.1 with a netmask of 255.255.0.0 (/16 as indicated).
if you try to ping 10.10.41.104, it will try

While your math is right you should look up supernetting and subnetting
somewhere.

OK well you don't need a layer 2 link to do what the OP wants...
Thanks,

Active directory will use the most specific network address that applies to
it. For instance, I set up a class-A address (or multiple in some companies)
that applies to all of the network space of the company and assign that to
the primary data center location. Then I start making more focused

You are mistaking machine subnetting and subnetting defined in AD. They are

i don't agree.
the /24 is included in the /16.
You won't have layer 3
Overlapping AD Subnet Boundariesis it really 10.10.0.0/16 or a mistake (/24) ?
Because your first site won't be able to joint the other one as it will think
it's local and won't sent packet to the gateway (if it's really a /16).
If it's a real /24, then it will works as expected (10.10.41.104
I don't know how AD would handle it. However, if someone else chimes in
with That will blow everything up! then it seems like maybe you could
go with /19 or /20 networks at the primary site in AD and then manually
add any of the other ones that don't fit nicely. Maybe that could save
you some
An AD client will try to associate itself with the site that it is most
specific for its IP.

What is the criteria you are using to say you need another site? That's the
first question to ask - maybe you think you need one and you don't --

What I would be interested to find out is:
1. What is the WAN link speed for the proposed 2nd AD site?
2. How much free available bandwidth do you have between the two desired
sites?
3. How many users sit in the proposed 2nd AD site?
If you have a fast reliable WAN connection (like a pair of
Yes. I have done this in organizations with hundreds of sites and a well
designed subnetting scheme.

Brian,
Thanks for the feedback - yes I think two T-1s or maybe even one is overkill.
But you do have to consider the WAN infrastructure before determining sites.
The number of users is a factor if you consider each user is probably on a
workstation. In the scenario we never had the
25 matches
