The simplest method of using DNSLINT is to verify DNS records for domain
controllers. To do this, run:

DNSLINT /AD IP of dc you want to check /S IP of DNS server authoritative for MSDCS
subzone

It also has the /QL functionality in order to check SRV records and the like.

This will run and generate an HTML-based report of records on this DNS server for
AD, confirming that CNAME records match up with A records. The easiest way to
interpret the results is to scroll to the very bottom of the page and look at the
summary report - any warnings or errors will be noted. All issues in the body of
the report are color-coded for easy viewing as well.

Recreating a missing VMFS datastore partition in VMware vSphere 5.x and 6.x

    Symptoms A datastore has become inaccessible. A VMFS partition table is missing.   Purpose The partition table is required only during a rescan. This means that the datastore may become inaccessible on a host during a rescan if the VMFS partition was deleted after the last rescan. The partition table is physically located on the LUN, so all vSphere hosts that have access to this LUN can see the change has taken place. However, only the hosts that do a rescan will be affected.   This article provides information on: Determining whether this is the same problem Resolving the problem   Cause This issue occurs because the VMFS partition can be deleted by deleting the datastore from the vSphere Client. This is prevented by the software, if the datastore is in use. It can also happen if a physical server has access to the LUN on the SAN and does an install, for example.   Resolution To resolve this issue: Run the  partedUtil  command on the host with the issues and verify if your output

  بأختصار ال FSMO Roles هى اختصار ل Flexible Single Operation Master و هى عباره عن 5 Roles فى ال Active Directory و هما بينقسموا لقسمين A - Forest Roles 1- Schema Master Role و هى ال Role اللى بتتحكم فى ال schema و بيكون فى Schema Master Role واحد فى ال Forest بيكون موجود على Domain Controller و بيتم التحكم فيها من خلال ال Active Directory Schema Snap in in MMC بس بعد ما يتعمل Schema Register بواسطه الامر التالى من ال Cmd regsvr32 schmmgmt.dll 2-Domin Naming Master و هى ال Role المسئوله عن تسميه ال Domains و بتتأكد ان مفيش 2 Domain ليهم نفس الاسم فى ال Forest و بيتم التحكم فيها من خلال ال Active Directory Domains & Trusts B- Domain Roles 1-PDC Emulator و هى ال Role اللى بتتحكم فى ال Password change فى ال domain و بتتحكم فى ال time synchronization و هى تعتبر المكان الافتراضى لل GPO's و هى تعتبر Domain Role مش زى الاتنين الاولانيين و بيتم التحكم فيها من خلال ال Active directory Users & Computers عن طريق عمل كليك يمين على اسم الدومين و نختار operations master فى تاب ال PDC Emu

Unlock the VMware VM vmdk file

  Unlock the VMware VM vmdk file Kill -9 PID Sometimes a file or set of files in a VMFS become locked and any attempts to edit them or delete will give a device or resource busy error, even though the vm associated with the files is not running. If the vm is running then you would need to stop the vm to manipulate the files. If you know that the vm is stopped then you need to find the ESX server that has the files locked and then stop the process that is locking the file(s). 1. Logon to the ESX host where the VM was last known to be running. 2.  vmkfstools -D /vmfs/volumes/path/to/file  to dump information on the file into /var/log/vmkernel 3.  less /var/log/vmkernel  and scroll to the bottom, you will see output like below: a.
