Most used Nslookup commands
Nslookup syntax
How to find the A record of а domain.
You can use this command to see how many A records are there and see the IP Addresses of each one.
Command line:
$ nslookup b1s.eu
How to check the NS records of a domain.
By checking the NS records, you can see which is the authoritative server for a specific domain.
Command line:
$nslookup -type=ns b1s.eu
How to query the SOA record of a domain.
With this one, you can see the start of authority and get information about the zone.
Command line:
$nslookup -type=soa b1s.eu
How to find the MX records responsible for the email exchange.
Here we are checking the MX records of the mail servers. You can see if all the mail servers are working well.
Command line:
$ nslookup -query=mx b1s.eu
How to find all of the available DNS records of a domain.
This lookup has a large scope. Here we want to see all the available DNS records. After seeing all of them, we can do specific lookups for different types of DNS records.
Command line:
$ nslookup -type=any b1s.eu
How to check the using of a specific DNS Server.
Apart from checking DNS records, you can use the Nslookup to review a particular DNS server and how it works. You can check if it is active or if it responds on time.
Command line:
$ nslookup example.com ns1.b1s.eu
How to check the Reverse DNS Lookup.
Many times you check the A records to see the IPs of a domain, but sometimes you need to verify if an IP address is related to a specific domain. For that purpose, we need a reverse DNS lookup.
Command line:
$ nslookup 8.8.8.8
How to check for a PTR record?
You can verify if an IP address belongs to a domain name by performing a reverse DNS query. For this purpose, you will need to check the PTR record that links an IP address to a domain name. You will need to put the IP address in reverse (192.168.1.25 changes to 25.1.168.192), and you need to add in-addr.arpa because it is stored in arpa’s top-level-domain.
Command line:
$ nslookup -type=ptr 25.1.168.192.in-addr.arpa
How to change the timeout interval for a reply.
You can manually choose the timeout time in seconds. You can increase it to give more time for the server to respond. You can also shorter it to see which servers can respond quicker.
Command line:
$ nslookup -timeout=20 b1s.eu
How to enable debug mode.
Debug mode provides important and detailed information both for the question and for the received answer.
Command line:
$ nslookup -debug b1s.eu
WMDC IN WINDOWS 11 OR WINDOWS 10
WMDC in Newer Versions of Windows
We have verified that this information is also applicable for computers running Windows 11.
If you absolutely need to use WMDC in a newer version of Windows, some possible methods to get it to work are listed below.
Most Common Method
The most common method used to get WMDC to work is to run our WMDC-fixes-for-Win10.msi patch utility, which may fix WMDC automatically after a restart.
The video below provides step-by-step installation instructions.
- Download the 64-bit drvupdate-amd64.exe or the 32-bit drvupdate-x86.exe. There are two parts to this installation.
- For more information see Microsoft Windows Mobile Device Center—ActiveSync.
- Download our patch WMDC-fixes-for-Win10.msi.
- Restart your computer.
- Open WMDC on your computer.
- Plug in a cable between your handheld device and computer to establish a connection.
If the WMDC has any problems after running this utility and a restart, visit our article WMDC Will Not Fully Install, Connect, or Uninstall.
Other Methods
There are other methods of getting WMDC to work, but they are older and usually unnecessary.
If you are using a previous version of Windows 10, you can use WMDC-Helper.exe.
- Save the above file to your desktop PC.
- Locate the file through File Explorer.
- Right-click on the file to Run as administrator (even if you are already logged in as an admin).
If you are still encountering problems, you can find other solutions in our Previous WMDC Fixes for Windows 10 article.

How To Access The Windows Startup Folder for All Users
Startup Folder on Windows 10, Windows 11, Windows Server 2019
- One Startup folder that operates at the system level and is shared among all user accounts
- Another Startup folder that operates at the user level and is unique to each user on the system
The All Users Startup folder is found in the following path:C:\ProgramData\Microsoft\WindowsStart Menu\Programs\StartUp
To access the “All Users” Startup folder in Windows 10, open the Run dialog box (Windows Key + R), type shell:common startup
The Current User Startup folder is located here:
C:\Users[User Name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
For the “Current User“ Startup folder, open the Run dialog and type shell:startup rather shell:common startup
Locating Windows Startup Folder Programs from Command Prompt
wmic startup get caption,command
Locating Startup Programs in Registry
To access it, press WIN+R and type REGEDIT and go to:
“HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run”
The startup folder path for the current user is C:\Users\[Username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup. The startup folder path for all users is C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp.
The following run keys are created by default on Windows systems:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnceHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
Run keys may exist under multiple hives. The HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnceEx is also available but is not created by default on Windows Vista and newer. Registry run key entries can reference programs directly or list them as a dependency. [4] For example, it is possible to load a DLL at logon using a "Depend" key with RunOnceEx: reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx\0001\Depend /v 1 /d "C:\temp\evil[.]dll" [5]
The following Registry keys can be used to set startup folder items for persistence:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell FoldersHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell FoldersHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell FoldersHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
The following Registry keys can control automatic startup of services during boot:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnceHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServicesOnceHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServices
Using policy settings to specify startup programs creates corresponding values in either of two Registry keys:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\RunHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
