Bal qiyaas^(Imagine) in aad leedahay hal albaab oo keliya oo gurigaaga ah. Ma jiro daaqado, ma jiro albaab barxad ah, kaliya hal albaab. Maxaa dhacaya haddii aadan furi karin albaabkaas? Guriga iyo wax kasta oo ku dhex jiraba, waxba kuma taraan.

Xakamaynta domainku waa sida albaabka, dareen ahaan. Mid ka soo booday. Waa albaabka laga galo gudaha waxyaabaha aad rabto. Hagaha^(Directory) firfircoon (AD) waa soobadaha albaabka. Waxay hubinaysaa aqoonsigaaga, waxay go'aaminaysaa haddii laguu oggol yahay inaad ka soo gudubto albaabka, iyo agabka aad geli karto markaad gudaha gasho. 

Haddii aad waddo shabakad nooc kasta ah oo aad leedahay hal maamule oo keliya, waxaad ku nooshahay guri hal albaab leh. Haddii ay wax ku dhacaan maamulaha domain-kaas, nidaamkaaga server-yada oo dhan ayaa kala baxaya. Had iyo jeer hay wax ka badan hal domain controller (DC).

Laakiin sidee ayaad u hubinaysaa in labada maamulayaasha domain ay leeyihiin xog isku mid ah? Aynu nidhaahno waxaad samaysay isbeddel la xidhiidha amniga hal DC. Waxaad doonaysaa inaad hubiso in isbeddelku ku soo noqnoqonayo DC-yada kale isla^(DCs) markaaba. Maxaad u sugaysaa 15 daqiiqo ama ka badan si ay ugu dhacdo jadwalka? Waxaad u baahan tahay inaad ku qasabto ku-celinta kontaroolayaasha bogga ee Hagaha Firfircoon^{(Active Directory)} . 

Waxaa jira 3 siyaabood oo tan loo wajaho; iyada oo loo marayo interface interface user ( GUI ), iyada oo loo marayo interface-line interface ( CLI ), ama iyada oo loo marayo PowerShell .

Ku qasbi Ku-noqoshada Maamulaha Domain-ka iyada oo loo marayo GUI^{(Force Replication Of Domain Controller Through GUI)}

Adeegayaasha Windows ayaa aad u isticmaala GUI^(GUIs) -yada , taas oo u fiican Maamulayaasha Nidaamyada^{(Systems Administrators)} cusub . Way fududahay in la barto oo mararka qaarkood waxay kaa caawinaysaa inaad sawirto waxa run ahaantii dhacaya. 

1. Gal mid ka mid ah DC-yadaada oo fur Goobaha iyo Adeegyada Hagaha Active^{(Active Directory Sites and Services)} .

1. U gudub goobta aad jeceshahay inaad ku soo celiso maamulayaasha domainka. Kordhi adigoo gujinaya falaarta ku xigta magaca goobta. Balaadhi Server^(Servers) -yada . Kordhi DC-ga aad jeceshahay inaad ku celceliso. Guji^(Click) NTDS Settings^{(NTDS Settings)} .

1. Shaxda saxda ah, midig-guji server-ka oo dooro Ku celceli Hadda^{(Replicate Now)} .

1. Iyadoo ku xiran inta DC^(DCs) -yada jira, tani waxay qaadan kartaa wax ka yar ilbiriqsi ilaa dhowr daqiiqo. Marka ay dhammaato, waxaad arki doontaa ogeysiiska, "Adeegyada Domain Directory Active Directory ayaa soo koobay isku xirka." Guji ^(Click) OK si aad u dhammayso

Ku qasbida maamulayaasha Domain-ka iyada oo loo marayo Taliska CLI^{(Force Replication of Domain Controllers Through CLI Command)}

Haddii aad aqoon u leedahay da'dii hore ee Windows CMD , markaa amarka repadmin waa adiga. Tani waa habka ugu dhaqsaha badan ee hal mar ah oo lagu qasbi karo nuqul ka mid ah DC. Haddi aanad aqoon u lahayn markaa waa wakhti ku haboon inaad wax ka barato Windows CMD^{(learn about Windows CMD)} . 

1. Gal^(Log) mid ka mid ah DC- yadaada^(DCs) oo fur Command Prompt .

1. Geli^(Enter) amarka soo socda, ka dibna taabo furaha Gelida^{(Enter )} .

repadmin /syncall /AdeP

1. Xog badan ayaa kor u qaadi doonta shaashadda. Haddii aad aragto in xariiqda u dambaysa ay akhrido, "SyncAll la joojiyay iyada oo aan wax qalad ah lahayn.", ka dibna amarka hoostiisa, DC - yada^(DCs) si guul leh ayaa loo soo koobay.

Ku Qasab Ku-noqoshada Maamulaha Domain-ka ee PowerShell^{(Force Domain Controller Replication With PowerShell)}

Haddii aadan u isticmaalin PowerShell nolol maalmeedkaaga, waa kaa maqan tahay. Runtii adiga ayaa kugu leh inaad barato PowerShell^{(learn PowerShell)} . Waxay kuu fududayn doontaa noloshaada, iyo haddii aad tahay Maamule Nidaamyada^{(Systems Administrator)} Junior- ka waxay si weyn gacan uga geysan doontaa inaad xirfaddaada u qaado tallaabada xigta.

Tallaabooyinkan waxaa lagu samayn karaa PowerShell CLI ee caadiga ah , laakiin waxaan ku samaynay PowerShell ISE si aan si wanaagsan u tuso amarrada iyo natiijooyinkooda. Waxaan dhisi doonaa qoraal aad kaydin karto ama xitaa u rogi karto cmdlet oo aad ka wici karto khadka taliska PowerShell .

1. Gal mid ka mid ah DC-gaaga oo fur PowerShell ama PowerShell ISE .

1. Kahor intaadan qorin qoraal kasta, ku keydi kan magac sifayn leh sida force-DCReplication.ps1 si aad dib ugu isticmaali karto. Geli koodka soo socda oo socodsii si aad u aragto sida uu u helayo dhammaan magacyada DC^(DCs) -gaaga .

(Get-ADDomainController -Filter *).Name

Eeg sida ay u soo celiso magacyada DC- yada^(DCs) ? Hadda waxaad ku shubi kartaa natiijadaas cmdlet soo socota. Dhuumaha waa xarafka toosan ( | ), kaas oo inta badan laga helo kiiboodhka wax yar ka sarreeya furaha Gelida^(Enter) .

1. Dhamaadka amarkii hore, geli koodka soo socda:

| Foreach-Object { repadmin /syncall $_ (Get-ADDomain).DistinguishedName /AdeP }

Amarka waa inuu u eg yahay sawirka hoose. Orod. Waa inay soo celisaa fariinta la mid ah ta dib ugu celinaysa Awooda Domain Controller Replication^{(Force Domain Controller Replication)} iyada oo loo marayo qaybta GUI ee sare. Haddii ay ku dhamaato, " SyncAll la joojiyay iyada oo aan wax qalad ah lahayn." ka dib way shaqeysay. 

Ma aragtay sida ay sidoo kale u isticmaasho amarka repadmin ?

1. Aan ku darno sadar kale si uu kaaga caawiyo inaad hubiso in ku celcelinta ay dhab ahaantii dhammaatay. Koodhkan soo socdaa wuxuu soo celin doonaa taariikhda iyo wakhtiga markii mid kasta oo ka mid ah DC- yadaada^(DCs) la sameeyay. Amarkan waxa la istcimaali karaa kaligiis wakhti kale haddi aad uun xiisaynayso markii ugu danbaysay ee DCs -gaaga la soo koobay. Geli^(Enter) koodka oo socodsii

Get-ADReplicationPartnerMetadata -Target "$env:userdnsdomain" -Scope Domain | Select-Object Server, LastReplicationSuccess

Natiijadu waa inay u ekaataa sawirka hoose. Waxaad hoosta ka arki doontaa taariikhda saxda ah iyo wakhtiga ku-noqoshada ugu dambeysay ay dhacday.

1. Si aad farta wax uga dhejiso, aynu ka dhigno wax soo saarkeeda mid hadal yar. Meel u dhow dhamaadka safka kowaad, geli | Out-Null inta u dhaxaysa /AdeP iyo garabka dhamaadka. Taasi waxay u sheegaysaa in aan la damin natiijada cmdlet. Natiijada kama dambaysta ah waxay u ekaan doontaa sawirka soo socda.

Ku celi^{(Keep’em Replicated)}

Hadda waxaad taqaan 3 dariiqo oo aad ku qasbi karto ku-celinta kontaroolayaasha domain ee AD. Waxa kale oo aad meel dhigtay far dib loo isticmaali karo oo PowerShell ah oo aad ka wici karto khadka taliska PowerShell mar kasta oo aad rabto. ^(PowerShell)Ma jirto wax cudur daar ah oo ku saabsan isbeddeladaagii u dambeeyay DC si aad u fariisato oo aad u sugto ku celcelinta soo socota ee la qorsheeyay, mar kasta oo ay taasi dhacdo.

Force Replication Between Two Domain Controllers in Active Directory

Imagine having оnly one door to your home. No windowѕ, no patio door, just one door. What happens if you сan’t open that door? The house, and everything in it, is useless to you.

A domain controller is like a door, in a sense. One with a bouncer at it. It’s the gateway to get inside to the things you want. Active Directory (AD) is the bouncer at the door. It checks your credentials, determines if you are allowed to go through the door, and what resources you can access once inside. 

If you’re running a network of any kind and only have one domain controller, you’re living in a house with one door. If something happens to that domain controller, your whole system of servers falls apart. Always have more than one domain controller (DC).

But how do you make sure that both domain controllers have the same information? Let’s say you made a security-related change on one DC. You want to make sure that change is replicated on your other DCs immediately. Why wait 15 minutes or more for it to happen by schedule? You need to force replication of the domain controllers in Active Directory. 

There are 3 ways to approach this; through the graphical user interface (GUI), through the command-line interface (CLI), or via PowerShell.

Force Replication Of Domain Controller Through GUI

Windows servers make use of GUIs a lot, which is good for novice Systems Administrators. It’s easier to learn and sometimes helps you visualize what’s really happening. 

1. Log in to one of your DCs and open Active Directory Sites and Services.

1. Navigate to the site for which you’d like to replicate the domain controllers. Expand it by clicking the arrowhead next to the site name. Expand the Servers. Expand the DC which you’d like to replicate. Click on NTDS Settings.

1. In the right pane, right-click on the server and select Replicate Now.

1. Depending on how many DCs there are, this could take less than a second to a few minutes. When it is complete, you’ll see the notification, “Active Directory Domain Services has replicated the connections.”. Click OK to finish.

Force Replication of Domain Controllers Through CLI Command

If you’re familiar with the good old Windows CMD, then the repadmin command is for you. This is the quickest one-off way to force DC duplication. If you’re not familiar then this is a good time to learn about Windows CMD. 

1. Log in to one of your DCs and open the Command Prompt.

1. Enter the following command, and then press the Enter key.

repadmin /syncall /AdeP

1. A litany of information will scroll up the screen. If you see that the last line reads, “SyncAll terminated with no errors.”, and then the command prompt underneath it, your DCs are successfully replicated.

Force Domain Controller Replication With PowerShell

If you’re not using PowerShell in your daily life, you’re missing out. You really owe it to yourself to learn PowerShell. It will make your life easier, and if you’re a Junior Systems Administrator it will massively help take your career to the next step.

These steps can be done in the ordinary PowerShell CLI, but we’ve done it in the PowerShell ISE to better show the commands and their results. We’re going to build a script that you can save or even turn into a cmdlet that you can call from the PowerShell command line.

1. Log in to one of your DCs and open PowerShell or PowerShell ISE.

1. Before writing any script, save this with a descriptive name like force-DCReplication.ps1 so you can reuse it easier. Enter the following code and run it to see how it will get the names of all your DCs.

(Get-ADDomainController -Filter *).Name

See how it returns the names of the DCs? Now you can pipe that result into the next cmdlet. A pipe is the vertical line character ( | ), that’s usually found on the keyboard just above the Enter key.

1. At the end of the previous command, enter the following code:

| Foreach-Object { repadmin /syncall $_ (Get-ADDomain).DistinguishedName /AdeP }

The command should look like it does in the image below. Run it. It should return a message just like the one back in the Force Domain Controller Replication Through GUI section above. If it ends with, “SyncAll terminated with no errors.” then it worked. 

Did you see how it also uses the repadmin command?

1. Let’s add another line to help you make sure that the replication really did complete. The following code will return the date and time of when each of your DCs was last replicated. This command could be used on its own at another time if you’re just curious when your DCs last replicated. Enter the code and run it.

Get-ADReplicationPartnerMetadata -Target "$env:userdnsdomain" -Scope Domain | Select-Object Server, LastReplicationSuccess

The result should resemble the image below. You’ll see at the bottom the exact date and time the replication last took place.

1. To put some polish on this script, let’s make its output a little less verbose. Near the end of the first line, enter | Out-Null between the /AdeP and the end bracket. That tells it to not put out the results of that cmdlet. The end result will look like the following image.

Keep’em Replicated

Now you know 3 ways to force replication of domain controllers in AD. You’ve also put together a reusable PowerShell script that you can call from the PowerShell command-line whenever you want. There’s no excuse for your latest DC changes to sit and wait for the next scheduled replication, whenever that may be.
