MCITP 70-640: Sites and Subnets

[@itfreetraining]

Thanks very much and thanks for watching.

[@LauraDimples]

All these videos are so well made. Thank you so much for taking the time to make them. You have made these topics so much easier to understand.

[@itfreetraining]

Thanks for the comment. Glad to hear you like the training videos.

[@itfreetraining]

Glad you like the video. IPv6 traffic works much the same as IPv4 for routing. In order to route traffic, you need one network adapter on each network. For Windows Server to route traffic between the two networks you need to install the RRAS role and configure it.

[@itfreetraining]

No problem at all, thanks for watching.

[@zoltron30]

I don't know what to say but the flow and the speed of these videos are top notch!!!

[@itfreetraining]

Thanks!

[@itfreetraining]

Thanks glad you like the videos. All you need to do is connect the sites together using a VPN. Once this is done your router will route traffic between the sites. Once this is done, add them to sites and services as stated in the video and it will work fine.

[@ramkumargupta9628]

you create awesome videos, visualization and knowledge very easy to understand. thank you!!!!

[@itfreetraining]

Thanks for comment. Much appreciated.

[@itfreetraining]

At present we do not sell any videos. Later on we may be doing this.

[@jingrichie2610]

can't help to say a big thank you to the video maker. Hope you can make more great training materials like AD migration plans. that's really helpful to me.

[@itfreetraining]

We're working on several new videos, stay tuned!

[@itfreetraining]

Thanks. Glad you like the video.

[@thomaja]

Did I mention the hero part? You make this unbelievably easy to understand. I'm going to name children after you! Well, they won't be my child, but SOMEBODY'S child. Thanks!

[@mradios]

Thank you, another good video for Sites and Subnets.

[@randyrosca6471]

Thank you! These are very well made and informative.

[@itfreetraining]

Thanks for the great feedback!

[@itfreetraining]

Sites are designed to mirror your network. If your networks are directly connected by a high speed link you can put both the subnets in the same site. If they are not well connected place the subnets in different sites. All computers can communicate with each other regards which site they are in. The sites are used by services like Active Directory to create replication that matches your network.

[@sesedmien1]

Thank you for your effort, you are awesome, guys !

[@itfreetraining]

A site is defined as two networks that are well connected. In this case the secure network and the commercial network are well connected. Even though there is a firewall between them the communication speed is quite high and thus they can be put in the one site. The idea the video was trying to get across is that multiple subnets could be combined together even if the IP address of these network are very different as long as they are well connected.

[@zoolanderhansel]

I wish my instructor explained this as well as you do. Thank you!

[@itfreetraining]

Thanks for watching.

[@itfreetraining]

It is recommended to have a DC in each site, however if you have a site that only has one or two uses it is hard to justify that cost from the business prospective. I have worked on a network where they removed the domain controller from a site due to the site only having two users. The users used offline files to access the files on the main network. This worked fine in this case so it can be done.

[@itfreetraining]

At present we do not sell the video. We may sell offline version later on, however the KZbin versions will always be free.

[@itfreetraining]

We are working on this videos at present. Will release them as soon as we can.

[@ChristoffMORLOCK]

Very useful video ! A big thank you !

[@itfreetraining]

+Christoff Morlock Thank you veyr much. We glad you found it to be useful and hope you'll enjoy the rest.

[@mohmednaeem]

Thank you very much for these videos!

[@itfreetraining]

Thanks for watching.

[@koiiijp]

Thank you for uploading such a helpful clip!

[@itfreetraining]

You're most welcome! Thanks for watching.

[@melateshetu2594]

Thank you for making my life easier!!

[@itfreetraining]

Thank you, we're glad you found the video helpful!

[@itfreetraining]

At this stage we won't be uploading any videos on these topics. With Windows Server 2012 it is possible these areas may be covered and we may do some videos on them.

[@itfreetraining]

This should work. Try removing 127.0.0.1 from the second domain controller. Also try and ping the first domain controller from the second domain controller to ensure that the network is working.

[@danielsoto4330]

Fantastic video! This is great material.

[@itfreetraining]

Thanks very much and thanks for watching.

[@yb1433]

This is really informative thanks for the clarification.

[@sahirhangu]

really very nice and simple videos to understand.. thx

[@nadunpeiris1058]

hey itfreetraining. Forst of all thank you soo much for all the helpful videos you have made. I have few questions about this Sites and Subnets... 1. is an AD site always the same as a physical network site? Please define the answer. 2. what are the charastaristic for a a site and a subnet? 3. does a site always host a DC? Please explain.

[@mAttacker89]

how do you do this for two different domains with a trust already established

[@Shawndz209]

Great video! I have a question. When I set up different subnets, how do I get the Servers to communicate over subnets? Is one nic configured for the main network and the other nic for the designated subnet?

[@nadeerbabu9561]

Thanks a lot Your explanations were very useful.

[@itfreetraining]

Thanks very much.

[@mohammadhabib3051]

Great explanation. Question again, how to configure TCP/IP for the domain controller being added in a child domain. Coz when doing dcpromo, it gives DNS error. I have the root domain as abc.com With IP: 192.168.1.1 subnet: 255.255.255.0 Then added a domain controller for abc.com IP: 192.168.1.2 subnet: 255.255.255.0 default gateway: 192.168.1.1 dns: 192.168.1.1 alternate dns: 127.0.0.1

[@simphiweraymondmajola375]

I think I can buy your videos if you sell them. I`ll browse your website tonight for more. Keep up Sir.

[@grennp]

Hi. I have two not yet DC's that will be promoted into a newly created site. I'm planning on adding the site, then the subnets, and then promoting the DC's afterwards. Is this the correct order to prevent problems with our production environment or should I promote the DC's first and then create the site?

[@tonyppe]

The biggest question I have but I cannot see the answer for - For my sites I allocate each site a block of address space which is a /20. This /20 provides a number of /24's. Each VLAN is allocated a /24 but the /20 is what is defined to the site as a whole. If we need a new VLAN at the site then the subnet is allocated from paritioned /20. If I create a site in AD Sites Services, can I define the subnet at the /20 level or do I need to specify each /24 individually? Obviously a huge time saving shortcut is to define the /20 in sites and services instead of 10+ /24's! But will it work? Will each computer know where the DC is at etc?

[@itfreetraining]

A better example of this is if you had two networks in the same building separated by a router. Perhaps the company leased out a new level and this was the only way to connect the levels. In this case it would make sense to have them connect together in the same site. The example in this video is probably not the best. In the real would, you would most like place a secure network in it's own site to make it easier to administrator. Less ports in the firewall would need to be opened.

[@itfreetraining]

I assume that by ADC you mean an extra domain controller added to the domain. In this case the 6 DC added would be ADC. However I have never seen that term used before. It would just be 7 DCs.

[@itfreetraining]

Probably the easiest way is to find out the IP address and subnet mask for a device or server in that network. Once you have this information work out the network id and use that.

[@vijayprabhu1983]

thanks for your reply sir ...in this video in NY there are seven DC...in that have you installed any ADC(Additional domain controller)..because my friend told if we Configure Sites and service we must have ADC(Add a domain controller to an excisting domain)

[@arantebw]

itfreetraining, thank you!

[@itfreetraining]

+Billy Wilson Arante You're welcome! Thanks so much for watching.

[@JamesThomas-wj6wm]

I'm a little confused... Washington has two subnets: one is behind a separate firewall. In the video, you said this should be two sites but in this video and the following one (AD Replication), there is one site. Am I seeing this incorrectly? Is a separate site really necessary in this case? Thanks for, not only posting these videos, but for answering our questions. You are my hero.

[@Aourik123]

is that relevant to the DNS scope réplication?

[@hassnawietbiga1996]

All respects sir .. Thank you very much .. I really wish you give more and more with more time ... Go in deep details sir please ...

[@theendryu]

and remember to do the needful

[@vijayprabhu1983]

Hmmm What to say i know this is very tough to work for free..your guide will give people to save their money...and increase their self study as me. and here is question when we creating sites do we need Additional domain controller in every location that we have.

[@Rambutharaju]

Hi nice video, I have configured sites and subnets And site links. The problem is when I logged into client machine the echo %logonserver% is showing different branch domain controller. So it means it is authenticated from different branch. Why it's getting authenticated from different branch when my local RODC is already in Up? However when I checked the site in client machine it is showing correct site. But logon server is showing different. Any idea?

[@maya1787]

Can u plz upload SCOM,SCCM,SCSM videos 2008 R2 plz...I need it to learn for Enterprise Edition please I love yr all videos...

[@sainathgiri955]

If there are two buildings with two subnets in one site how the traffic will be high ? Are you considering only one dc per site ?

[@itfreetraining]

You could have one DC per site if lower latency was required.

[@algerietjr]

Hi , i would like to thank you about this videos , i want to ask how i can apply that online how i can connect my sites together ? and also about vpn how to access from online ?? thanks very much

[@Darnozz]

Hello I have a question concerning the creation of a new subnet. when I press new subnet, I enter the ip address with the subnet and choose the site object but I can't click ok. it's all grayed out

[@53nat0r]

Great stuff. Thanks

[@Aourik123]

Hi First of all thank you for your reply. I did every thing described in the link you have given me. the réplication is done properly but when i restart one of the tow root domain controllers, it takes longer to boot up. and then i get the message mentionned previously

[@itfreetraining]

This probably can be fixed given enough time and research. However, if it is only the one Domain Controller, it probably easier to try and remove the Domain Controller from the domain and promote it again. If it does not have any FSMO roles on it that should not be to difficult.

[@fidsoft2011]

can we create two sites on a single domain ... i need to divide my network into two subnet say (subnet a and subnet b ) they should not communicate with each other but need to communicate with server what to do ... ? any answer :)

[@aborucu]

itfreetraining So how does the two subnets defined as subnet and secure subnet link with the concept of windows domain ? Are they in the same domain or not.

[@itfreetraining]

Sites and subnets define the network topology of the forest. Using this, Active Directory will work out which links it needs to use to replicate information between different domain controllers and different domains.

[@mysteriously01]

how do u you what ip subnet is for the site!!!

[@drwombat]

What about the new york site with the 192.168.20.0/24 subnet? how do you add multiple IPV4/IPV6 subnets to one site? Also, what about the secure subnet in washington that gets it's own site? Can you add two sites with the same name? I understand this is probably just extra info added to be helpful but it doesnt round out the video with the inclusion of the extra information.

[@_DCF4L]

Is this demonstration for Server 2008 R2 or Server 2012 R2?

[@ChristoffMORLOCK]

+Rudy I think it's 2008 R2

[@itfreetraining]

+Rudy This was made on Windows Server 2008 R2, but the process is much the same for Windows Server 2012

[@Aourik123]

HI everyone, Could you please help me fixing some DNS problems in an Active directory environment? Here is my Situation. I have one forest with 10 child domains. the root domain has tow domains controllers: DC1 has the Windows 2008 Server R2 with DNS ,The RID Master,The PDC Emulator, The Infrastructure Master Roles installed.DC2 has GC The Schema Master and The Domain Naming Master, DNS installed in Windows 2008 R2. the tow DCS are installed on an Vmware hypervisor. and the others 10 child domains are in Windows 2000 server.Note that Dc1 and Dc1 were in Windows 2000 server and were migrated to the Windows 2008 R2. The problem is When DC1 and DC2 restarted. i get the following: The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed. I wish that i was clear and anyhelp is welcome SAID

[@itfreetraining]

Have a look at this article if you have not already. technet.microsoft.com/en-us/library/cc735842(v=ws.10).aspx If there is a problem with DNS, what you can try doing is changing the DNS on the DC to another DNS server. This may be enough to fix the replication problem. I would also check for replication problems. Maybe something is not configured correctly.
