By default, non-admin domain users do not have permissions to install the printer drivers on the domain computers. To install a driver, the user should have local admin privileges (for example, by adding to the local Administrators group). This is great from the point of security because the installation of an incorrect or fake device driver could compromise PC or degrade the system performance. However, this approach is extremely inconvenient in terms of the IT-department, because it requires Support-team intervention when a user tries to install a new printer driver.

First each driver is time frequency corrected individually, then the sum of the individual drivers are corrected as a combined unit. When True Time Domain Correction is checked, the whole speaker will be time domain corrected as one single entity. This is the only TTD option for passive speakers.

You can allow non-administrator users to install printer drivers on their Windows 10 computers (without the need to grant local Admin permissions) using Active Directory Group Policies.

Configure GPO to Allow Non-Administrators to Install Printer Drivers

At first, create a new (or edit an existing) GPO object (policy) and link it to the

Expand the following branch in the Group Policy editor: Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > Security Options. Find the policy Devices: Prevent users from installing printer drivers.

Set the policy value to Disable. This policy allows non-administrators to install printer drivers when connecting a shared network printer (the printer’s driver downloaded from the print-server host). Then you can set the policy value to Disable, any unprivileged user can install a printer driver as a part of a shared printer connection to a computer. However, this policy does not allow downloading and installing an untrusted (not-signed) printer driver.

Adding Printer Device GUIDs Allowed to Install via GPO

The next step is to allow the user to install the printer drivers via GPO. In this case, we are interested in the policy Allow non-administrators to install drivers for these device setup classes in the GPO section Computer Configuration > Policies > Administrative Templates > System > Driver Installation.

Enable the policy and specify the device classes that users should be allowed to install. Click the Show button and in the appeared window add two lines with device class GUID corresponding to printers:

• Class = Printer {4658ee7e-f050-11d1-b6bd-00c04fa372a7};
• Class = PNPPrinters {4d36e979-e325-11ce-bfc1-08002be10318}.

You can find a full list of the device class GUIDs in Windows

When you enable this policy, members of the local Users group can install a new device driver for any device that matches the specified device classes.

Note. You can enable this policy through the registry using the command:

You can find the list of allowed to install device GUIDs under the registry key: HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindowsDriverInstallRestrictionsAllowUserDeviceClasses.

Now save the policy.

Configuring Point and Print Restrictions Policy

In Windows 10 there is another feature related to the UAC (User Account Control) settings, which occurs when you try to install a shared network printer. If the UAC is enabled, a message appears in which you want to specify the credentials of the Administrator. If UAC is disabled, then when you try to install the printer under the non-admin user—the system hangs for some time and finally displays an error message: “Windows cannot connect to the printer. Access is denied“.

To solve this problem, you need to disable the policy Point and Print Restrictions. This policy is located under the Computer and User Configuration section of the GPO editor. In order to enable compatibility with previous versions of the Windows operating system, it is recommended to disable both policies. They are located in the following sections:

• Computer Configuration > Policies > Administrative Templates > Printers;
• User Configuration > Policies > Administrative Templates > Control Panel > Printers.

Then you should disable this policy for Windows 10 computers, the security warnings, and elevated command prompts do not appear when the user tries to install the network printer or when printer driver is updating.

Note. You can disable Point and Print Restrictions via the registry. Use the following command:

If you want to restrict the list of print servers from which users are allowed to install print drivers without admin permissions, you need to set the Point and Print Restriction policy to Enabled.

Then enable the option “Users can only point and print to these servers”. In the
“Enter fully qualified server names separated by semicolons” specify a list of your trusted print servers (FQDN).

Under the “Security Prompts” section select the “Don’t show warning or elevation prompt” for the policy parameters “Then installing drivers for a new connection” and “Then updating drivers for an existing connection”.

Test the Policy to Allow Users to Install Printer Drivers

It remains to test the policy on client computers (requires restart). After rebooting and applying Group Policy settings, users will be allowed to install printer drivers without Admin permissions.

Tip. After installing the update KB3170455, released on July 12, 2016, in order to successfully install the printer, the printer driver must meet the following requirements:

• The driver must be signed by a trusted digital signature;

• The driver must be packed (Package-aware print drivers). Installing of the unpacked (non-package-aware) drivers through Point and Print Restrictions is impossible.

This means then when you try to install the non-package-aware v3, you will see the warning “Do you trust this printer?” with the Install driver UAC button, which requires printer drivers installation under the admin account.

You can check your driver type on the print server under the node Print Management > Print Servers > Server Name > Drivers. For package-aware print drivers, you can see the True value in the Packaged column.

Time Domain Driver App

See WindowsTimeServiceDev for discussion of this topic.

Beginning with Windows 2000, Microsoft includes the Windows Time Service with all versions of Windows. Initially, the pupose of Windows Time Service was to keep all clocks on the Windows network loosely synchronized to support Kerberos authentication, which is time-sensitive to a degree. Windows Time Service is also known as 'w32time', and can be configured with the registry, Group Policy editor GUI tool, or the command-line tool w32tm.

Windows domain controller machines that are part of an Active Directory domain are automatically configured to act as time servers. The domain controller who is the Primary Domain Controller Emulator in the network is automatically configured to poll time.windows.com as a time source, and all subsequent domain controllors automatically obtain time from the Primary Domain Controller Emulator.

Windows domain member servers and domain member clients are automatically configured to receive time from domain controllers on the same network.

Stand-alone Windows servers and clients are automatically configured to poll time.windows.com at one-hour intervals. The time.windows.com server (actually a cluster of servers) is maintained by Microsoft. However, time.windows.com is notoriously unreliable and heavily loaded, so configuring a different time source or multiple sources is probably wise.

An example configuration, suitable for a Windows 2003 standalone server or Primary Domain Controller Emulator in a Active Directory domain:

C:>w32tm /config /update /manualpeerlist:'0.pool.ntp.org,0x8 1.pool.ntp.org,0x8 2.pool.ntp.org,0x8 3.pool.ntp.org,0x8' /syncfromflags:MANUAL

The above configuration tells Windows Time Service to use four servers from the NTP Pool, and use a client-mode association (identified by the ,0x8 after each server name) to contact them. This configuration is analgous to server directives in the configuration file for ntpd. Note that this configuration should not be used on Windows servers or clients that are members of an Active Directory domain, unless you absolutely want them to ignore time from Active Directory domain controllers on the network.

A second example, suitable for a laptop computer that is a member of a Windows Active Directory domain:

C:>w32tm /config /update /manualpeerlist:'pool.ntp.org,0x8' /syncfromflags:MANUAL,DOMHIER

Time Domain Driver Jobs

The above configuration tells Windows Time Service to both Active Directory domain controllers and pool.ntp.org as time sources, so that domain controllers are used as time sources when the laptop is on the netowork, but pool.ntp.org is used when the machine is 'on the road' but still connected to the Internet (at a WiFi hot-spot in your local coffee house, for example).

For detailed information, please see the Windows Time Service Technical Reference.

Time Domain Direct Sampling

Limitations

The implementations in Windows 2000 and Windows XP are SNTP clients only, and not suitable for use as a server, although Windows 2000 domain conrollers incorrectly serve time at stratum 2 always, regardless of their time source configuration. This is a violation of the SNTP RFC, which states that SNTP systems can only act as servers if they have a local reference clock attached.

More recent versions, such as those in Windows 2003, Vista, and Windows 2008 are documented by Microsoft to be compliant implementations of the NTPv3 RFC 1305.

Windows Time Service servers report a precision of -6, and do not appear to interpolate time between system clock ticks. This limits their absolute accuracy to ±16 ms, far below that of the reference ntpd implementaion. However, this accuracy is suitable for many networks and applications.

Reference clock support for the Windows Time Service is possible with third-party drivers. At this time, such drivers are essentially non-existent, meaning Windows Time Service can only act as a time server at Stratum 2 or below.

Comments

We should document the 0x8 flag. Talk about the problems with the default w32time setup and noepeer, and how we want to lose the 'it's probably a windows client' exemption for noepeer even if we're not actually setting up a peering association.
