Frequently Asked Questions: Networking

Q-4. Where did netdom go? I can't find it in Windows 7.

A-4. Install the AD components for RSAT on your Windows 7 computer and you'll get netdom.

Q-3. Windows 7 supports offline domain join, and TechNet says the following:

"The base64-encoded metadata blob that is created by the provisioning command contains very sensitive data. It should be treated just as securely as a plaintext password. The blob contains the machine account password and other information about the domain, including the domain name, the name of a domain controller, the security ID (SID) of the domain, and so on. If the blob is being transported physically or over the network, care must be taken to transport it securely."

Does the blob for offline domain join expire after a period of time if the machine is not joined to the domain? And can it be revoked somehow before it is used?

A-3. No and no.

Q-2. How do you enable logon via dialup networking in Windows 7?

A-2. You can do this as follows:

1. Open the Network and Sharing Center.
2. Click Set up a connection or network, then click Setup A Dialup Connection.
3. Enter your dial-up information
4. Select the Allow Other People To Use This Connection checkbox.
5. Finish the wizard and save the connection, then restart the computer.
6. After the restart, select Switch User and then look for the blue button in the lower right corner next to the Restart/Hibernate/Shutdown button. 

Q-1. How do you enable Wake-on-LAN (WoL) on a Windows 7 computer that supports this feature?

A-1. Depending on your computer's network adapter and on how your computer's BIOS is configured, you may be able to use Wake-on-LAN (WoL) to wake your computer from power-saving states such as Sleep, Hibernate or Hybrid Sleep. To make sure your computer is configured to use WoL, follow these steps:

1. Open Control Panel.
2. Click System and Security.
3. Click Administrative Tools.
4. Double-click Computer Management.
5. Under System Tools, select Device Manager.
6. Under Network Adapters, right-click on your network adapter and select Properties.
7. Select the Power Management tab.
8. Make sure that the following checkbox is selected: Allow this device to wake the computer. Doing this will cause your network adapter to listen for the following types of network packets:

• A directed packet to the MAC address of your network adapter
• A NetBIOS name resolution broadcast for your local computer name
• An ARP packet for the IPv4 address of your network adapter
• An IPv6 Neighbor Discovery packet for your network adapter's solicited-node multicast address

If your network adapter detects any of these packets, Windows will wake up. If your computer wakes up too frequently however, you can repeat steps 1-7 of the above procedure and then make sure that the following checkbox is also selected: Allow only a magic packet to wake the computer. Doing this will cause your network adapter to listen only for a special type of packet called a magic packet, which is a standard wake-up frame typically sent from a systems management station that targets a specific network interface on the network.
