Servers showing up multiple times in Sites and Services

I happened to catch something odd this morning while looking into another issue. When i open our domains Sites and Services and click on one of our 4 corporate DC's (3vm's one physical one of them being tested in production with server 2012 R2).
I'm seeing that a few of our servers in remote locations are showing up multiple times. However when I go to this server and click on who it's replicating with it's only showing one server and sometimes not even the same one as the corporate server.
Here is a screen shot I took.
The red's are all the same server (sorry boss has mandated we aren't allowed to put out the names for some reason). I'm a little confused as to what could be causing this. Anyone have any ideas?

Without better/more screenshots, it a bit hard to tell what you are seeing. However, in your statement
"...I'm seeing that a few of our servers in remote locations are showing up multiple
times. However when I go to this server and click on who it's replicating with it's only showing one server and sometimes not even the same one as the corporate server."
Replication is one-way connections and are always a PULL scenario. So for instance if
COR-DC-03 is replicating from COR-DC-01, the replication link will only be on COR-DC-03. COR-DC-01 may or may not replicate from 03. It may actually be replicating from another DC. Also, the AD ISTG (intersite topology generator) will always try to find the
most efficient replication and ensure that each DC has at least 2 replication partners, and there is no more than 4 hops to another DC. You have a number of sites and I assume there are DCs in there as well. All of those DCs need to replicate with one another.
Perhaps if you can draw or otherwise illustrate the issue you are seeing that would help.

New Domain Controller does not show in our different site's Domain controller's Sites and Services

Hi,
we have two sites in our AD environment. OMA site and NY site. we have three domain controllers in our OMA site and two domain controllers in our NY site. All our DCs are windows server 2008R2 except one in our OMA site that is 2003R2 the domain
functional level is also 2003R2.
We decided to raise our functional level to 2008R2. I added a new domain controller in our OMA site and transferred all FESMOS from the DC that was running 2003R2 to this new domain controller.
the issue now is that our NY site does not make any connection with the new domain controller in OMA site. it does not even show it under sites and services. I have checked the DNS settings and everything. if you try to replicate the connections
from NY site it gives the following error: "The naming context is in the process of being removed or is not replicated from the specific server."
can anyone plz tell me why this is happening mt brain is just frozen at this moment and cant figure out why is this happening

Just noticed this replication issue has been going on for a while now but we never noticed until I added new DC. here is the error log for the NY site DC.
Log Name:      Directory Service

Description:
It has been too long since this machine last replicated with the named source machine. The time between replications with this source has exceeded the tombstone lifetime. Replication has been stopped with this source.
The reason that replication is not allowed to continue is that the two DCs may contain lingering objects. Objects that have been deleted and garbage collected from an Active Directory Domain Services partition but still exist in the writable partitions
of other DCs in the same domain, or read-only partitions of global catalog servers in other domains in the forest are known as "lingering objects". If the local destination DC was allowed to replicate with the source DC, these potential lingering object
would be recreated in the local Active Directory Domain Services database.
Time of last successful replication:
2013-05-16 15:26:38
Invocation ID of source directory server:
9236ac56-d046-4632-b072-acbe823c5f6c

Tombstone lifetime (days):

The replication operation has failed.
User Action:
The action plan to recover from this error can be found at
http://support.microsoft.com/?id=314282.
If both the source and destination DCs are Windows Server 2003 DCs, then install the support tools included on the installation CD. To see which objects would be deleted without actually performing the deletion run "repadmin /removelingeringobjects
<Source DC> <Destination DC DSA GUID> <NC> /ADVISORY_MODE". The eventlogs on the source DC will enumerate all lingering objects. To remove lingering objects from a source domain controller run "repadmin /removelingeringobjects <Source
DC> <Destination DC DSA GUID> <NC>".
If either source or destination DC is a Windows 2000 Server DC, then more information on how to remove lingering objects on the source DC can be found at
http://support.microsoft.com/?id=314282 or from your Microsoft support personnel.
If you need Active Directory Domain Services replication to function immediately at all costs and don't have time to remove lingering objects, enable replication by setting the following registry key to a non-zero value:
Registry Key:
HKLM\System\CurrentControlSet\Services\NTDS\Parameters\Allow Replication With Divergent and Corrupt Partner
Replication errors between DCs sharing a common partition can prevent user and compter acounts, trust relationships, their passwords, security groups, security group memberships and other Active Directory Domain Services configuration data to vary between
DCs, affecting the ability to log on, find objects of interest and perform other critical operations. These inconsistencies are resolved once replication errors are resolved. DCs that fail to inbound replicate deleted objects within tombstone lifetime
number of days will remain inconsistent until lingering objects are manually removed by an administrator from each local DC. Additionally, replication may continue to be blocked after this registry key is set, depending on whether lingering objects are
located immediately.
Alternate User Action:
Force demote or reinstall the DC(s) that were disconnected.

MacBook shows up multiple times under 'Shared' in finder

My MacBook keeps showing up multiple times under 'Shared' in the Finder sidebar. All sharing services are turned of in System Preferences. The number in the computer name is automatically added. When I change the computer name to another name, all existing 'ghost computers' stay there in the sidebar. How do I get rid of these?

The same podcast shows up multiple times

In iTunes, the same podcast shows up multiple times. There is only one copy of the file on my computer, and the file it located in the right location, but in iTunes, the same podcast is repeated two or more times. When I delete a single podcast and try to play its copies, iTunes notifies me that it can't find the file. I believe this happens when I use the import folder utility and add music in the iTunes music default location (which includes the podcasts as well as the music I want to import). Does anyone know how to keep this from happening?
Thanks

Well, the easiest way would be to stop using the import folder utility. Sounds like you're adding the podcast multiple times. You're probably doing it to other files as well...

Artists show up multiple times in Artist listing

When I get a listing of songs by artist on my iPhone, some artists show up multiple times in the list. It's not that way on my computer. For instance, Death Cab for Cutie shows up twice, with different albums listed with each. However, some albums show up in both listings, but each with only partial selections of the songs on that album. So the first instance of DCC has album 1 with tracks 1-4 of the album and the second instance of DCC has album 1 with tracks 5-11.
I went so far as to highlight all my DCC songs on iTunes on my computer and pasted DCC into the Artist line of each song and then re-syncing. No change.
Any clues?

Just wanted to add to this problem. I'm having the problem with Death Cab for Cutie and Kings of Leon. They show up twice on the artist list on my iPhone, but only once on my computer.
My biggest concern is that it's taking up twice the space on my phone.
If anyone has a solution to this it would be great!
Thanks.

IPhone 4 on ios 5 - recurring events show up multiple times

I updated my iPhone 4 to ios 5, and ever since, recurring events are showing up multiple times on the same day. When I sync, it seems that another copy is added to my iPhone's calendar (only one event is in iCal). I originally had a custom event that repeated every Tuesday and Wednesday. I tried to change this into two events - one for each day - and it still has the issue of multiple events on the same day.
Notes I add to these events do not sync back to my computer, either.
I have tried wiping the calendars from the phone and syncing with what is on my computer, but I continue to have the same problems.
Any help/advice out there? It's more of an annoyance than anything!

At least one of them is only using the cellular data or wi-fi at the moment. His computer is on the fritz and he has not been able to sync with itunes for a while because of it. I am not sure about the other colleague as she is out fo the office at the moment.

Is this on an iOS device ? If it is then do you currently have Settings > iBooks > Show All Purchases set 'on' on it ? When I did I was getting multiple copies of ibooks showing, turning it 'off' fixed it for me (with it 'off' only ibooks that you've downloaded/synced to the app show on the bookshelf) - you can still redownload ibooks via the Purchased tab in the ibookstore in the app.

Hyper-V - Sites and Services using multiple subnets

Good evening,
Im currently setting up a test domain where I want to use multiple subnets.
My current setup is the following
- Host PC running Hyper-V manager with 1 physical NIC that connects to my router (192.168.0.1)
- Virtual Machine running Windows Server 2012 R2 - This is my domain controller aswell as DNS and DHCP server. IP address for this is 192.168.0.200
Now what im wanting to do is also create 2 more domain controllers but 'pretent' that they are in two completely different locations running off multiple subnets. Lets say one is in America and one is in Australia.
I want the addresses of these two machines the following
DC (America) - 192.168.1.1
DC (Australia) - 192.168.2.1
The reason i'll be doing this is im going to be working with Sites and Services to give me a better understanding of it.
Please can someone give me help with how I can achieve this.
Thanks.

One way to do this is to:
Setup 1 internal vSwitch. We'll use a different VLAN and subnet for each AD Site. For example, you can use VLAN 101, 102, and 103, and subnets 192.168.101.0/24, 192.168.102.0/24, and 192.168.103.0/24. This consistency will be very helpful later on.
Create a VM to act as a router, with 3 vNICs. Configure each of the 3 vNICs on a different VLAN, with a static IP on the corresponding subnet, such as 192.168.101.5, 192.168.102.5, and 192.168.103.5. Setup static routing rules if needed using Route Add
for example.
Create 3 DCs. Each DC will have a single vNIC. It can be in its own domain and forest. For example, DC101 will have a vNIC on VLAN 101, with IP 192.168.101.10/24, GW 192.168.101.5. Setup DNS on each DC.
Setup DHCP on each DC with a scope that corresponds to its subnet. For example, on DC101 setup a scope that provides IPs from 192.168.101.100 to .150, with /24 mask, .5 gateway, and .10 DNS.
As you add other VMs, if you VLAN-tag its vNIC with VLAN ID 101, it will get IP address from DC101 on the 192.168.101.0/24 subnet since DHCP ARP broadcasts will not cross the router (VM we setup earlier) by default.

Route mail and Active Directory Sites and Services configuration

Folks,
I have a problem in the internal email routing. My network is spread across various regions and the branch offices are connected together in a mpls network (full mesh). Every region has its own Exchange Server with all roles installed and the smtp connection
to the outside world is linked to two Exchange servers in the headquarter server farm.
The problem is that internally I often see emails going across the Exchange Servers in the branch offices where there is low bandwidth (from 3 to 5 Mbps), thus email are sent first to these servers instead of going immediately to the Exchange hosting
the mailboxes of the intended recipients. This happens also with inbound emails.
This causes slowness in the email system and sometimes also the network with these branch offices suffers from packet loss or very high latency.
I know that Exchange is a site-aware application and uses the Active Directory topology for message routing and to communicate with the services that are running on other Exchange 2013 computers. For this reason I have checked the Active Directory Sites
and Services and surprisingly I have found that there are no sites, no subnets, nothing has been defined but the default settings, included the Inter-Sites transport which contains the default DEFAULTIPSITELINK.
Apart from the fact that clients use logon servers which are not supposed to use in the far remote offices, I am concerned of changing the Exchange Infrastructure whilst the email system is running and I would like to ask your opinion about my next steps:
1) Create subnets for every office
2) Create sites and then link them to the subnets done in point 1
3) Delete the DEFAULTIPSITELINK and create new site links based on the costs (network speed) in order to determine the best routing server. I have 5 remote offices with 5 different network bandwidth, so I'll have to create 5 IP site links: high cost for
link with slow network, low cost for fast network.
4) (Optional) Configure the Exchange-specific cost using the Set-AdSiteLink cmdlet to the AD IP site links created previously
Apart from the valid questions on why the previous Exchange Administrator have forgotten to set up the Active Directory (Topology) Sites and Services...
...And why have chosen to install all Exchange Roles to each server when there was no reason to do that (there are two servers connected to the external smtp gateways in the headquarter, so in my opinion the Exchange Servers in the remote branch offices
should have had only the mailbox and the cas role)...
As a matter of fact, my idea is to go further and create the sites,subnets and the ip site link. If I still notice a wrong email flow, I can configure an ad-hoc Exchange-specific cost using the Set-AdSiteLink cmdlet. Does this sound reasonable to you guys
or I am taking the wrong decisions?
Thanks

Thank you very much for your link. This is exactly the page I have read just before posting my question here. It is not easy for me to understand why this has been setup this way by a Microsoft certified engineer.
There are specific rules to follow when Active Directory and Exchange are located in multiple sites and I am not a skilled Exchange Administrator... he keeps saying that it is correct and also tells that if I go forward with my ideas there is the
risk to increase the level of complexity. I prefer more complexity than default setting, and as a consequence of that, connectivity problems!
Hopefully everything goes well. I will post my results here once I have done the changes
Regards

AD Sites and Services and Best Practices

Hey All,
I am new to OES, but not new to AD. I am in an environment in which DSfW was recently setup to support VDI testing.
I notice that there is no configuration under AD Sites and Services. We have multiple sites, with DCs setup at each site. The consequence of not having Sites and Services configured is that machines/users in site "A" are logging in through site "B" domain controllers. Obviously, this is not ideal nor best practice. Secondly, this leads me to wonder how the domain controllers are replicating since I do not see NTDS entries in Sites and Service MMC for the domain controllers, yet I do see that AD data is replicating by comparing databases (simply adding a new user on one DC I see it added on the secondary DCs). So I know it's replicating, but apparantly not using AD schema?
One other question I have about DSfW is regarding the migration from a mixed environment to a full AD environment. We are deploying AD primarily due to VDI initiatives, and currently only testing this. Looking further down the road for planning purposes I have to wonder if it's possible to stand up a 2008 R2 server, join it to the domain, dc promo it, FSMO transfer, then decommossion the DSfW systems. This would leave us with purely Windows DC environment for authentication. Is this something some people have done before? Is it a recommended best path for migrating? Cause I also see others creating a second AD environment, then building the trusts between DSfW's domain and the "new" domain (assuming these are not in the same forrest). That would be less than ideal.
Thanks in advance for any responses...

Excellent! I feel sane now :) I can live with this, as long as it's expected/normal.
It sounds like you need sites and services, but once that's in DSfW,
why migrate from DSfW to MAD if DSfW works for your VDI initiative?
You are correct. I am simply planning and making sure all the options are in play here.
I would rather not get too deeply reliant on DSfW if it will make any future possible migration more difficult. Otherwise, DSfW is extremely convenient....I am impressed actually.
I also believe there may be a way we can control the DC used for specific "contexts" (or OUs as Microsoft calls them). So if I have a group of users in a particular OU that reside at a particular branch I think I should be able to set their preferred domain controller....and if so, that means sites & services becomes nearly irrelevent. I would be ineterested to talk to people who are using DSfW with multiple sites in play.

Sites and services

guys,
i would like to create 3 dc servers with different ip´s. My domainname will be mytestingsite.com and the 3 dc's will all be residing on a differten site. 1 will be in my datacenter(in city 1), 2 others will be in city2 and city3.
How should i configure my sites and services and my dns.
many thanks.
johan

Simply proceed like the following:
Create three AD sites: City1, City2 and City3
Move Domain Controllers computer accounts to their correct sites
Create all the subnets you use and link to their correct sites
This will minimize the amount of AD replication traffic and will make your Windows clients access the closest DC when an authentication is required or when they need to get applied GPOs/scripts.
