Just to point out that in Microsoft is all PULL technology, not PUSH. Meaning, if something changes within, it will not "SEND" data to other Domain Controllers. DC that has changes will NOTIFY their replication partners to come and pick up data. Thank you for brilliant series.
This channel is so extensive, there's never a single topic that isn't covered. Don't know if I should google things or just go to itfreetraining because I end up coming here regardless haha.
I watch and recommend your videos to everyone I know. Thank you for not telling lame jokes during your presentation like CBT Nuggets does. I can't watch their videos because of it. Keep up the great work!
You are incredible, I never watched that much simple video on replication topic, My all doubt have been cleared, Thank you so much. Please share videos on AD partitions and LDAP as well.
This is perhaps the best video to learn about sites and replication. Appreciate your efforts for explaining with animation. This has certainly helped to learn the concepts. Glad I stumbled upon this...Great Work!!!!
No you do not require a domain controller in order to set up a site. When you run DCPromo it will ask you for a site to put the domain controller in. For this reason I would always set up the site first so that the domain controller can be put in the correct site straight away without having to be moved later. You could even setup the domain controller in a different network for that site and ship it to the other site pre configured. Glad to hear you like the videos.
I have seen one time this video for learning AD replication... It was a fantastic video for online learning user.. Now i have get clear vision about AD replication. Thanks lot....
You can set up a site without a DC in that site. You could add a DC later that day, a month, a year later or not at all. If there are no DC's at the site there is nothing to replicate to. If you want to apply group policy at the site level you would need to create a site in order to do this. This is one reason why you may create a site that does not have a DC in it.
One of the best video I find in UA-cam for Active directory Sites and Services, Video and Sound quality is very good, the speed of training was excellent, no rush at all like many other video. Beautiful and Excellent job. Many thanks in advance Only one comment, if the Video get tagged with number would be very easy to follow the training, for example why was mentioned in the beginning of video "my previous video" not sure which to look for. Thanks again. :))
Yes, SMTP is a better choice if your network is not very reliable. Just remember it does not not support file repletion so you will still need to use IP in some cases. However, there is no reason SMTP can't be the main protocol and IP mainly used for file replication. I would schedule the SMTP to run first and IP later to cover both bases. The SMTP would then replicate all the required AD traffic before IP ran. If you don't have much file rep, IP could be schedule IP rarely.
In most cases changes will not take effect until replication has occurred so you are correct. Account lockouts however are replicated straight away to the PDC emulator. So if the account is locked the PDC emulator will know about it straight away.
Yes it is SMTP. The reason it was used was because the TCP/IP was not as established as it is today when Active Directory was first created. For this reason they needed a protocol that would work over links that were not connected via TCP/IP. Even though SMTP is still available, I doubt that is used much now days.
Host only should work. If the servers are on a different subnet you can also create a separate network for them.If you want to access the internet you will need a router. We have a video series coming up explaining how to do this. First attempt to ping the other server and make sure there is a network connection. Try running repadmin /Showrepl and see if there are any replication partners. If you have just prompted the server, it sounds like a DNS problem. Configure DNS to the other DC.
Congratulations for the incridible videos, you guys are awesome, It's helping me a lot to study for the 70-640 exam. Keep up with the good work, the channel have my support, Thanks again.
Truly wonderful videos, I'm super impressed and they're helping me a lot at the moment with a course I'm doing. However I'm so shocked throughout this video series to see how primitive AD services still are - still assuming horrible network connections, using SMTP to transfer "not mail", the age of consoles and their complexity of use and the fact that so many options seem to be just about everywhere, nothing is very concentrated and simplified when there is clearly MASSIVE potential for simplification. I say this even today while using Server 2019, because not a lot has changed to the fundamental architecture.
Thank you for this video. Site links was very well explained. I liked the graphics verses someone doing it on a white board talking off the cuff. You're clear and concise - well thought out in presentation. Thank you.
I assume that all your branches are connected directory to the office. If this is the case you need to set up a 6 links. One from each branch back to the main office. If the offices are connected to each other, you can also create site links between them for redundancy if you wish.The point to remember this the connections that you crate should mirror your network. For example if branch 4 was connected to branch 5 to the head office, you should create a link between 4 and 5 and 5 and office.
If for example an admin made the change, the change may be made on a Domain Controller that is different from what the user is using. If the user connects to a remote file server that server may decide it needs to authenticate the user or obtain details for the user it will contact a local Domain Controller. Laptop user changes network, e.g. wired to wireless, may need to authenticate again. The password is just an attribute of the user.
I am not sure what you are referring to. When you promote a server to a Domain Controller it will ask which site you want to put it in. You can always move it later on if you need to. I am guessing in this case we may have deleted all the sites before we did the demo and recreated them for the demo. For this reason the servers when back into the sites there were in before when the sites were recreated.That is all I can think of that may have caused what I think you are referring to.
All though it is not recommend it is something you could try. I worked on such a configuration and it work well most of the time. Since you only have 6 sites you could create 3-4 different site links with 3 sites in each. This should give you some redundancy. If you want a full mesh you would need to create all the site links which is administrative a lot of work, but that what you need to do for a full mesh. This is why full mesh is not always that popular.
We have them all connected to main office through VPNs, some links slower than others. I don't think any of the branch offices have to go through another branch to connect to our main office if this is what you ask. BTW great video thanks for posting.
ISTG is missing in this video as it generates the site links between the sites and automatically chooses bridgehead server if bridge head server goes down.
I don't understand one aspect of the intersite transport links. We have in our organization 6 branch offices outside of our main office. All the branch offices have only 1 domain controller and our main office has 2 dc's. How would I set up the intersite links? Should i just set up branch 1 to hq, branch 2 to hq, branch 3 to hq, and so on? Or do i need to make other links such as branch 1 to branch 4, branch 5 to branch 6. This seems a bit convoluted. I have bridge all site links to on.
All the videos that I have seen so far from you have been very well done. I do have a question about this one though. Do you have to have a DC in the remote location to set up a site?
thanks for your video, it helped me a lot.. my question is: in practical environment if I scheduled the replication to occur after business hours to another domain, do you think that will affect on the permit for any user, I mean If I deleted as I am administrator at another site, that will not affect on him until next day and he can logon in that day.. what do you think ???
your video is very helpful to me I have learnt lots of important thing, could you please create a video how to troubleshoot AD replication via command line and DC diag command of use.
Hello, thanks for the tutorial.I don't understand one thing, though: How does a DC know that the DC from which it replicates has the NEWEST sysvol in the domain? What if the lowest cost of a link links the DC to another DC that doesn't have the sysvol replicated either. Thank you
+GotterVibez Inevitably and ideally, the replication will make it out to all of the DCs. More technically, Active Directory performs a lot of assignment and configuration in the backend such as utilizing the Knowledge Consistency Checker (KCC) and designating an Intersite Topology Generator (ISTG) to ensure the accuracy of replications. Mainly though, the KCC is able to compare using determined configuration errors to identify the potential gaps that need replication.
This is amazing work, I know the server in your videos is Win 2008 R2 and not much has changed how AD works. Is it still possible to have these excellent videos on a latest version of Win Server 19? or even 2016 ?
Just to point out that in Microsoft is all PULL technology, not PUSH. Meaning, if something changes within, it will not "SEND" data to other Domain Controllers. DC that has changes will NOTIFY their replication partners to come and pick up data. Thank you for brilliant series.
I love ITFReeTraining. It is one of the few things I can rely on to be accurate and they make things easy to understand.
Thanks so very much for your feedback!
passed my 70-410 and 11 with the help of your videos. Re taking 70-412 by clearing the weakest concepts from your videos.
This channel is so extensive, there's never a single topic that isn't covered. Don't know if I should google things or just go to itfreetraining because I end up coming here regardless haha.

Thanks very much. It is good to know that our videos are appreciated. Thanks for recommending the videos to others, that helps us a lot.
No problem at all, it is good to hear that you liked the video.
I had lot of confusion in sites n Services. After seeing this video comprehensively cleared all of my doubts.Thanks for the video...

Really appreciate the videos. Way easier to understand and better presented than any Learning Tree or Global Knowledge class.
Thanks very much. Glad we could help.
Sir this is the first video that I have watched with soo much explained about replication from beginning to expert
Thanks for watching.
Excellent. Glad to hear you liked the video.

thanks for supplying clear and concise information from an IT student in Training. Soo soo good
Thanks very much and thanks for watching.
wonderful work, no one provides these kinds of videos for free.
Glad you like the videos.
Very professionally done and very well explained. Thank you for all your hard work. These are great. Can' wait for the Server 2012 content.
I never seen a better video explaining replication
Thank you!

Only one comment, if the Video get tagged with number would be very easy to follow the training, for example why was mentioned in the beginning of video "my previous video" not sure which to look for. Thanks again. :))
The best I like about the training is the basic and clear understanding of concept.
Thank you once again...
Thanks very much.
One of the most awesome presentation i have been given to assist, really thank you very much.
Love these videos. You do a great job of explaining what could be complex tasks and theories.
As usual, another awesome video from you all at itfreetraining! Thank you for them all.

Thanks very much for wathcing.
Thanks for the comment. Glad you liked the videos.
Excellent video about AD replication between sites

Thanks very much. Videos on Windows Server 2012 R2 on the way.
Nice explained...your voice is great. ISTG strategy is missed..!Different between ISTG and KCC!

by comparing the update sequence numbers i believe
Thank you.
Dude you are my hero
No doubt this video is very help full.
Thanks, glad we could help.
thanks for uploading the video....its gr8
wow, excellent explanation.
Thanks for the like, sub and watching the video. More video to come. :)
currently studying for the 412 exam and once I go through an exam topic i like to look at a video to reinforce my understanding...
Thanks for choosing ITFreeTraining!
