I Upgraded domain of 2003 to 2008. I have a domain 2008 R2 and Active directory integrated with DNS service. I have 2 domain controllers, and these domain controllers have configurated DNS server service, but I have problems with DNS service and I see that the DNS server is not complete because i don´t see the _msdcs zone in forward lookup zones
Can anybody say me what can i do for recovery the _msdcs zone? or if I can re-create the DSN server service
Thanks for your help.

I have been through all the online help forums, videos, and other online research and I cannot seem to find a solution to my problem. I was trying to access folders located on the file share service on the DC and am unable to access as I get the error code 0x80070035 which is the "Network path cannot be found".
Also my silly doubt is, Could this happens due to malware infection.
Please reply my answer. Thanks in advance.

Hi all,
"Enable computer and user accounts to be trusted for delegation" rights is disabled for Administrator account as shown below
despite changing delegation option being "Trust this computer for delegation to any service (Kerberos only)" as shown below
I am doing this to change the name of the domain controller that requires the above mentioned right, or else I get "access denied error".
Pls tell me how to enable the above mentioned right to the current user who is Administrator ?
Tks in advance

I am in the process of decomissioning the 2008 DC so I have moved all FSMO roles to another DC. The old DC is getting time from the newly promoted PDC as are the domain clients it seems.
I have gone through this below more times than I should have needed, the info is clear and it seems to work. however I still get an error from an elevated cmd prompt.
C:\Windows\System32>w32tm /query /status
or
C:\Windows\System32>w32tm /query /configuration
The following error occurred: Access is denied. (0x80070005)
pushd %SystemRoot%\system32
.\net stop w32time
.\w32tm/unregister
.\w32tm/register
.\sc config w32time type= own
.\net start w32time
.\w32tm/config/update /manualpeerlist:"0.pool.ntp.org,1.pool.ntp.org,2.pool.ntp.org,3.pool.ntp.org",0x8/syncfromflags:MANUAL /reliable:yes
.\w32tm/resync
popd
Why am I not able to run a query on the PDC with an elevated cmd prompt and I do have domain rights in all the right areas! I have never had this problem before.
Thanks, Charlie

Hi All,
Hello,
Sure everyone's familiar with...
2020 LDAP channel binding and LDAP signing requirement for Windows
https://support.microsoft.com/en-gb/help/4520412/2020-ldap-channel-binding-and-ldap-signing-requirement-for-windows
From what I can tell, LDAP connections will be made secure;
Current Windows computers are capable of LDAP signing. But non-Windows computers may not be; instead, they should use STARTTLS to switch to LDAPS.
The domain controllers I am looking at are already listening on TCP/636;
Get-ADDomainController -filter * | select name,ldapport,sslport name ldapport sslport ---- -------- ------- [redacted] 389 636 [redacted] 389 636 [redacted] 389 636 [redacted] 389 636 [redacted] 389 636
If a computer isn't capable of LDAP signing [typically, non-Windows], then it should use the STARTTLS to use LDAP channel binding.
That's where the fun begins!
LDAPS is LDAP over TLS.
TLS requires a certificate.
Where should this certificate come from?
Should it be from an internal certification authority, which won't be trusted by [non-Windows domain member] LDAP clients by default. But internal hosts can check the certification authority CRLs.
Or, should it be from an public certification authority (https://letsencrypt.org/ might do!)
BUT if I use a public certification authority, then do my LDAP clients now need to be able to examine the public certification authorities certificate revocation list or OCSP? That may not always be possible.

I am working on a AD migration project, i have created trust between both the domains but i am unable to resolve a host name in Domain B from Domain A.
What are the key areas to check and resolve this issue.
Thanks in advance.
Error: 5014
The DFS replication service stopped communication with partner XXXXX for replication group domain system volume due to an error. the service will retry the connection periodically.
What is the best way to resolve this issue.
Thanks in advance.
I try to automate cert requests for LDAPS certificate. When i request the my cert template the certificates private key is exportable. But never, when I try with certreq.
This is my Inf:
[Version]Signature="$Windows NT$ [NewRequest] ; At least one value must be set in this section Subject="CN=dc01" KeySpec=1 KeyLength=4096 Exportable=TRUE ProviderType=12 RequestType=PKCS10 KeyUsage=0xa0 [RequestAttributes] CertificateTemplate="KDC_TEMPLATE" [Extensions] _continue_ = "dns=dc01&" _continue_ = "dns=dc01.mydomain.dom&" _continue_ = "dns=mydomain.dom&" _continue_ = "dns=MYDOMAIN&" _continue_ = "dns=ldap.mydomain.dom&"
Then I try
certreq -new c:\_scripts\request2.inf c:\_scripts\result.txt
certreq -config pki.mydomain.dom\myCERT-CA -submit c:\_scripts\result.txt c:\_scripts\certificate.cer
certreq -accept c:\_scripts\certificate.cer
I got a powershell script to put the cert to NTDS Store.
But the private key ist never exportable when I script this, only when I use MMC an request manual.
Does anyone has an idea, what I do wrong??
