Terminal Service Manager is a utility that is used to view information about Terminal servers in trusted domains. It provides information about all sessions, users, and processes for each Terminal server. By using Terminal Service Manager, a user can perform the following tasks:

• Connect to another session.
• Disconnect from a session.
• Log off a user from a session.
• Send a message to a user.
• End a process.
• Reset a session.

The Active Directory Migration Tool (ADMT) is used to migrate from an earlier implementation of Windows NT to Windows Server 2003 or Windows 2000 Server. ADMT supports not only migration from Windows NT 4.0 to Active Directory but also interforest and intraforest migrations. ADMT is designed to migrate an Active Directory schema from one forest to another, regardless of whether a change in operating systems is involved.

ADMT 2.0 has many new features such as a command-line interface and a better interface to work with Microsoft Exchange Server. ADMT also supports a user-account password migration.

Microsoft Baseline Security Analyzer (MBSA) is a tool that includes a graphical and command line interface that can perform local or remote scans of Windows systems. It runs on computers running Windows 2000, Windows XP, or Windows Server 2003 operating system. MBSA scans for common security misconfigurations in Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, Internet Information Server (IIS) 4.0 and above, SQL Server 7.0 and 2000, and Office 2000 and 2002. It also scans for missing hot fixes in several Microsoft products, such as Windows 2000, Windows XP, SQL Server etc.

HFNETCHK.EXE is a command-line utility that checks the patch status of one or more machines across the network. Earlier HFNETCHK was a separate command-line utility. However, its latest version is built into MBSA version 1.1, and is used by MBSA to display information in a graphical format. Users can run the HFNETCHK utility using the MBSACLI.EXE /hf command. The MBSACLI.EXE program is installed as a part of MBSA.

DNS server is a computer that runs the Domain Name System (DNS) service. It contains host name-to-IP address mappings, IP address-to-host name mappings, information about the domain tree structure, etc. A DNS server is also used to resolve DNS client queries.

IPCONFIG is a command-line utility that displays the current TCP/IP configuration, such as IP address, subnet mask, default gateway etc., of a networked computer. It refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. Users can run IPCONFIG from the command prompt whenever they need to know the status of a computer’s TCP/IP configuration.

Subnet mask is a binary number associated with a TCP/IP address. It allows a computer to distinguish which parts in an IP address correspond to the network ID and host ID portions of the address. In binary representation of subnet mask, the bits set to 1 correspond to the network ID, and the bits set to 0 correspond to host ID. All IP interfaces on the same network segment must use the same network ID and subnet mask. The subnet mask is a required configuration item.

A superscope is used in a DHCP server to assign IP addresses from multiple scopes to DHCP clients on a physical network. It contains a list of member scopes that can be activated together. It allows a DHCP server to provide leases from more than one scope to clients on a single physical network. The advantage of creating superscopes is to ease the administration in a multi-netted environment.

Network adapter is a hardware device that works as an interface between a computer and a network. It is used by the computer to access the network. A network adapter is also known as an adapter card or network interface card (NIC).

Automatic Private IP Addressing (APIPA) is a Windows feature, which allows household users and small business users to create a functional single subnet TCP/IP network without manually configuring the TCP/IP protocol or setting up a DHCP server.
