Sub Domains...

[Timetable]

Hi

 

been reading the articles one 2 domains on 1 lan and windows domains 1 or 2 and still couldn't find the information I was after.

 

We are a high school and are combining with our middle school (3 tier system up north) and we want the teachers who work across both sites to still have the single sign on benefts we have got here.

 

We will have a wireless link between the two sites and this will carry data aswell as the Voip for the phones.

 

On the middle site we have been told to setup a sub domain and this will help stop broadcasting over the network and should make things easier... I kinda agree with this but have no knowledge of setting up sub domains or there benefits.

 

So,

 

Is this the best solution and does anyone know of an idiots guide for adding a sub domain to our existing network.. i have been bamboozling myself reading up on this and just need a simplified view.

 

I take it we create a new sub domain in active directory sites and then setup all the services for this domain.. this domain will have a sever there to process logons locally.

 

i take it we need a new ip range, and i take it a new domain name ie newsite.domain.local

 

or have i read this wrong...

 

any advice would be terrific and as i said an idiots guide even better...

 

Thanks in advance

Why not create a domain trust with information syncing across the network, would be much easier.

 

Subdomains are fairly difficult to set up

 

*edit* fixed a bodged error from my phone!

Basically the way to do it is you will need a domain for each site (a DC cant do more than 1 site at a time)...

 

So it would be

 

- Campus.local.sch.uk

--- Upperschool.local.sch.uk

----- OU's

--- middleschool.local.sch.uk

----- OU's

 

You would need 3 DCs in this instance, 1 at each site, and 1 to control both sites. Its the only way I can see it working.

easiest way in my opinion is why not just put a layer 3 switch at each end and plug your servers into a specific VLAN, it'll stop broadcasts where they arn't wanted, and you could have just those servers on that VLan everything else on another ?? I dont now whether something along those lines would work ?? also It would be easier if you could add the server to the existing domain and making it a RODC or A DC on the same domain, this would keep you AD structure and your single signon would work fine - even better if you have Exchange which uses the same credentials.

A couple of questions,

What AD level are you running at currently?

How fast is your wireless link and how stable is it?

[Timetable]

The wireless link i have been told is a proxim 11mbp link and is very stable. The county used to use it for internet provision for the site.

 

There will be a router I am told at that end to connect us together.

 

Our AD level is at the Enterprise i would imagine but can check when i get in on monday..

I cant imagine for one second that any shared setup will work over 11mbs, if thats the speed your running at then you will not be able to provide any sort of single sign on let alone VOIP!.

 

A sub domain would allow for delegation, but what you probably need is to setup sites in AD instead.

whoops my mistake 11MB's sorry kinda big difference....

[featured_spectre]

How stable is that connection and what is the actual throughput. Is there a chance of wiring between the sites?

 

11MB still isn't that fantastic if you are talking about cross site connectivity.

[Timetable]

There's no chance of wiring he schools are located either side of a public welfare.

If you have line of sight I would look into microwave link as its still a bit low and thats before you have net and profiles routing through.
