Using the arp command allows you to display and modify the Address Resolution Protocol (ARP) cache. An ARP cache is a simple mapping of IP addresses to MAC addresses. Each time a computer’s TCP/IP stack uses ARP to determine the Media Access Control (MAC) address for an IP address, it records the mapping in the ARP cache so that future ARP lookups go faster.
If you use the arp command without any parameters, you get a list of the command’s parameters. To display the ARP cache entry for a specific IP address, use an -a switch followed by the IP address. For example:
Dec 16, 2015 The next most useful trick is to be able to clear out NVRAM with the same command string. To delete all nvram variables just use the following syntax: nvram -c. For changes to take effect, you must reboot the Mac, thus unless you’re doing something else you may want to just initiate a reboot from the command line while you’re there.
You can display the complete ARP cache by using -a without specifying an IP address, like this:
ARP is sometimes useful when diagnosing duplicate IP assignment problems. For example, suppose you can’t access a computer that has an IP address of 192.168.168.100. You try to ping the computer, expecting the ping to fail; but lo and behold, the ping succeeds. One possible cause for this may be that two computers on the network have been assigned the address 192.168.168.100, and your ARP cache is pointing to the wrong one.
The way to find out is to go to the 192.168.168.100 computer that you want to access, run ipconfig /all, and make a note of the physical address. Then return to the computer that’s having trouble reaching the 192.168.168.100 computer, run arp -a, and compare the physical address with the one you noted.
If they’re different, that two computers are assigned the same IP address. You can then check the Dynamic Host Configuration Protocol (DHCP) or static TCP/IP configuration of the computers involved to find out why.

The OneDrive sync app (OneDrive.exe) can be installed on Windows 7 and later. It can also be installed on macOS. For info about deploying the OneDrive sync app on macOS, see Configure the new OneDrive sync app on macOS
The new OneDrive sync app can be used with SharePoint Server 2019, but not earlier versions of SharePoint Server. For more information about the restrictions and limitations of the OneDrive sync app, see Invalid file names and file types in OneDrive and SharePoint.
Important
If your users are currently using the OneDrive sync app (Groove.exe), and you want to move them to the OneDrive sync app, see Transition from the previous OneDrive for Business sync app before proceeding.
The OneDrive sync app uses Windows Push Notification Services (WNS) for optimum performance and battery life. Make sure you allow access from your network to the endpoints that OneDrive uses.
If the computers in your organization are running Windows 10, they already have the new sync app installed. If the computers have Office 2016 or Office 2013 (Home & Student, Home & Business, Professional, Personal, Home, or University) installed, they might also have the new sync app.
Note
Office is installed per machine, whereas OneDrive is installed per user by default. Learn about installing OneDrive per machine
To set registry keys on computers in your domain, install OneDrive and copy the OneDrive.admx and OneDrive.adml files from %localappdata%MicrosoftOneDriveBuildNumberadm to your Group Policy central store. For more info, see Use Group Policy to control OneDrive sync app settings.
In Configuration Manager, select Create Device Collection, and follow the steps in the Create Device Collection wizard.
Save the OneDriveSetup.exe installer for Windows to your local computer or a network share. Download the Production ring OneDriveSetup.exe installer for Windows or download the Deferred ring OneDriveSetup.exe installer for Windows.
Download the sample Configuration Manager package. It's a .zip file that contains the script installer deployment type. For more information about packages and programs in Configuration Manager, see Packages and programs in Configuration Manager.

Note
The script installer deployment type already has a detection method script and will correctly assess the installation. Also, there is an uninstall switch, which means that you can easily remove the OneDrive sync app, if necessary.
Copy the installer to a folder in the Configuration Manager source content share.
In Configuration Manager, select the Software Library workspace. Under Application Management, right-click Applications, and then select Import Application.
Select the sample package.
On the bottom of Configuration Manager, select the Deployment Types tab, right-click the deployment, and to update the Content location, edit the properties.

If you don't use the sample package, run the following command using Microsoft Endpoint Configuration Manager:
(where pathToExecutable is a location on the local computer or an accessible network share).
Note

This command must be run at user logon and using Administrator permissions. It must be run for each user on a machine. For an example of how to deploy an .exe on every user account, see How to deploy the OneDrive sync app with Configuration Manager.
If you run the command with no command line parameter, users will see the installation status. After installation, OneDriveSetup.exe will automatically execute OneDrive.exe and display OneDrive Setup to users. If you run the command with the /silent parameter, OneDrive.exe will be installed transparently and OneDrive Setup won't appear. You'll need to run OneDrive.exe with an additional command. If you want to control the launch of OneDrive across your organization, we recommend using the /silent parameter.

The new OneDrive sync app for Windows now supports syncing IRM-protected SharePoint document libraries and OneDrive locations. To create a seamless IRM sync experience for your users, deploy to your users' computers the latest Rights Management Service (RMS) client from the Microsoft Download Center. Even if these computers have the Azure Information Protection client installed, which includes the RMS client, the OneDrive sync app still needs a separate installation of the RMS client from the Microsoft Download Center.
To silently install the RMS client on computers, use the /qn switch as part of the command-line options of the Microsoft Windows Installer Tool (Msiexec.exe). For example, the following command shows the silent mode installation (assuming the RMS Client installer package is already downloaded to C:Downloads)
You can have the setup file on a network share and use managed software deployment to run the msiexec command.
Note
The sync app does not support IRM policies that expire document access rights.
To help users sign in, you can use silent account configuration or one of these methods:
Use the following URL to start OneDrive Setup on users' computers. When users click to begin Setup, a sign-in window will appear for users can enter email address.
Use the following URL with each user's email address to start Setup and prepopulate user email addresses in the sign-in window.
Run the following command using Configuration Manager script:
It starts the OneDrive process. If users haven't set up any accounts, it displays OneDrive Setup. To display OneDrive Setup specifically to users who haven't set up an account for your organization, use the command line parameter:
