Network administration is a crucial aspect of managing and maintaining an efficient and secure network infrastructure. In a Windows environment, network administration involves the configuration, monitoring, and troubleshooting of various network components and services. This article aims to provide a comprehensive guide to network administration in a Windows environment, covering topics such as network configuration, user management, security, and performance optimization.

Examples:

1. Network Configuration:

   • Configuring IP addresses and subnet masks using the Command Prompt (CMD):

     ipconfig /all
     netsh interface ipv4 set address name="Ethernet" static 192.168.0.10 255.255.255.0

   • Configuring DNS settings using PowerShell:

     Get-DnsClientServerAddress
     Set-DnsClientServerAddress -InterfaceIndex 2 -ServerAddresses ("192.168.0.1", "8.8.8.8")

2. User Management:

   • Creating a new user account using CMD:

     net user username password /add

   • Modifying user account properties using PowerShell:

     Set-LocalUser -Name username -PasswordNeverExpires $true

3. Network Security:

   • Enabling Windows Firewall and configuring rules using CMD:

     netsh advfirewall set allprofiles state on
     netsh advfirewall firewall add rule name="Allow Port 80" dir=in action=allow protocol=TCP localport=80

   • Configuring network access control using Group Policy:

     gpedit.msc
     Computer Configuration -> Windows Settings -> Security Settings -> Windows Firewall with Advanced Security

4. Performance Optimization:

   • Monitoring network performance using Performance Monitor (PerfMon):

     perfmon
     Add Counters -> Network Interface

   • Optimizing network settings using CMD:

     netsh int tcp show global
     netsh int tcp set global autotuninglevel=normal
