Hi,
I am writing a document for a disaster recovery for our DC's.
We have 2 server 2019 Hyper-v hosts and each have 1 VM DC. we backup each DC with Backup exect and hyper-v agent.
My question is, How to recover the VM DC that has the 5 FSMO roles?
I understand becuase we using Hyper-v higher then 2012 and VM DC is also 2012 R2 we can just resore the VM DC and no issue with Generation-ID. is this correct? or we still have to do a non autherative resotre of the DC with FSMO roles?

Can we migrate Certificate services from one domain to new domain.
we are planning a green field hybrid AD .. and migrate all our different ADs to one New AD?
is there a migration plan available in such scenario or should we setup new ADCS role in new AD?
#adcs #pki #CERTIFICATE #AUTHORITYOn a newly setup Windows 2019 Server Essentials domain, a user requires to RDP into their workstation.
I have added the user to the Builtin Remote Desktop Users group but they are still unable to RDP into either the server or their workstation.

Hi Guys,
I have created a secondary (backup) domain controller and successfully managed to promote it. However, It doesn't contain netlogon directories. On running DCDIAG command, I get the following output.
Notes:
The current primary DC is running Windows Server 2003 with Server 2003 forest functional level. (Name - pdc, pdc.domain1.com)
My new server with errors is on Windows Server 2012 R2 (DC01, DC01.domain1.com)

Is having Windows 2016 AD schema in mixed Win2008R2\Win2012R2 domain supported?
I am trying to find some official confirmation or a Microsoft document.
Hi all,
Provide script windows servers C drive clean up as best practices. Which will helpful.
We are having WS2008R2/2012R2 DCs, and have upgraded to WS2016 DCs. Now we are planning to move the FSMO roles to new DCs in our root and child domain. Root forest is empty, and child domain has all users/groups/app data.
As we are planning to move all the FSMO roles in both domains (root forest & child domain). I already made plan to first move all the FSMO roles in both env. and then start decommissioning the older DCs first root and then child domain, but manager said first move all the FSMO roles in forest and decommission the older DCs from root, then move moved all FSMO roles in child domain and do decommissioning. I said that their steps are neither advisable nor recommended way to do so, but they are keep insisting on it. If we do so and go by manager's way, it will impact our whole AD infra.
Any article where the FSMO roles movement and decommissioning in this type of environment.
Just wanted to confirm is it the possible way Manager suggested? I don't think so.
Any thoughts on this?

I want to restrict internet browsing on domain controller. Already I'm following the Microsoft recommendation.
Does it possible to restrict internet for DC alone. we have firewall in perimeter network.
We have configured strict firewall policy for our enterprise. I have read few article via windows firewall we can block internet access however windows firewall was disabled on DC. Normally every enterprise no body use windows firewall on DC.
Please assist with your answer whether internet block is possible in DC ?
Hi,
My RODC showing the following event.
"The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error."
But DNS service is ok and AD is functioning properly. So why this type of event is created and how can I solve the error?
Or, is this error avoidable??
Thank You,

Hi All,
I have a weird issue when creating a linked custom attribute pair in AD.
The process I am following is firstly create the forward attribute with the LinkID of 1.2.840.113556.1.2.50. This apparently auto generates the LinkID. Reload schema and create the back-link attribute using the OID of the forward attribute. This goes all OK apart from when I look at the attribute details, the link ID is a negative number. For example..
The forward attribute is
The BackLink attribute is
From all the information I have read, the forward attribute link ID should be positive even number and the back-link should be positive odd number.
I'm using powershell to create the attributes. Forward attribute script is..
$RootDSE = [System.DirectoryServices.DirectoryEntry]([ADSI]"LDAP://RootDSE")
# Retrieve the Schema naming context, the distinguished name of the Schema container in AD.
$SchemaNC = $RootDSE.schemaNamingContext
# Bind to the Schema object.
$Schema = [ADSI]"LDAP://$SchemaNC"
# Create object of class "attributeSchema" with common name "MyCompany-MyAttribute".
$NewAttr = $Schema.Create("attributeSchema", "cn=Test-SoftwareDeliveryPrimaryUser")
$NewAttr.Put("attributeID", "1.2.840.113556.1.8000.2554.1.1")
# Unicode string attribute, similar to the title attribute."
$NewAttr.Put("oMSyntax", 127)
$NewAttr.Put("attributeSyntax", "2.5.5.1")
$NewAttr.Put("isSingleValued", $False)
$NewAttr.Put("isMemberOfPartialAttributeSet", $False)
$NewAttr.Put("searchFlags", 1)
$NewAttr.Put("lDAPDisplayName", "Test-SoftwareDeliveryPrimaryUser")
$newAttr.Put("LinkID", "1.2.840.113556.1.2.50")
# Create the new attribute.
$NewAttr.CommitChanges()
# Assign optional attributes.
$NewAttr.Put("description", "Test AD attribute -Forward")
#$NewAttr.Put("rangeLower", 1)
#$NewAttr.Put("rangeUpper", 128)
# Update the new attribute.
$NewAttr.CommitChanges()For the Back link, I am using...
$RootDSE = [System.DirectoryServices.DirectoryEntry]([ADSI]"LDAP://RootDSE")
# Retrieve the Schema naming context, the distinguished name of the Schema container in AD.
$SchemaNC = $RootDSE.schemaNamingContext
# Bind to the Schema object.
$Schema = [ADSI]"LDAP://$SchemaNC"
# Create object of class "attributeSchema" with common name "MyCompany-MyAttribute".
$NewAttr = $Schema.Create("attributeSchema", "cn=Test-SoftwareDeliveryPrimaryUser-BL")
$NewAttr.Put("attributeID", "1.2.840.113556.1.8000.2554.1.2")
# Unicode string attribute, similar to the title attribute."
$NewAttr.Put("oMSyntax", 127)
$NewAttr.Put("attributeSyntax", "2.5.5.1")
$NewAttr.Put("isSingleValued", $False)
$NewAttr.Put("isMemberOfPartialAttributeSet", $False)
$NewAttr.Put("searchFlags", 1)
$NewAttr.Put("lDAPDisplayName", "Test-SoftwareDeliveryPrimaryUser-BL")
$newAttr.Put("LinkID", "1.2.840.113556.1.8000.2554.1.1")
# Create the new attribute.
$NewAttr.CommitChanges()
# Assign optional attributes.
$NewAttr.Put("description", "Test AD attribute -Backlink")
#$NewAttr.Put("rangeLower", 1)
#$NewAttr.Put("rangeUpper", 128)
# Update the new attribute.
$NewAttr.CommitChanges()Environment is a test environment consisting of a single Windows Server 2012 R2 Domain Controller
I could manually declare the LinkID, but I was trying to keep user error out of the equation and thus wanted to use the auto generated method. Anyone one know why I am getting a negative number as a linkID
Thanks for taking the time to read this
