You may use the following command from the command prompt or Windows PowerShell to view the architecture, physical or virtual, of the local or remote host on a network. In the second command substitute the %computername% variable with the hostname of the host to be queried.

You may use the following Windows PowerShell cmdlet to get a list of all of the Windows Servers in your Microsoft Active Directory (AD) domain. In particular, it will provide the hostname of the server, operating system, and service pack then output the results to a CSV file.

Lately, I’ve developed a greater motivation and interest in learning the ins and outs of Information Technology (IT) architecture. Ask any IT professional and he or she will tell you there is so much to learn and that technology is constantly changing. With that said, I’m currently asking and answering the following questions as I learn new technology as well as day to day troubleshooting on the job.
By default, the Disk Cleanup utility is not present on Microsoft Windows Server 2008 R2. However, copying the files below to the appropriate directories will make the utility available for use. After the files have been copied enter the command Cleanmgr.exe into a command prompt or Microsoft Windows PowerShell session to start the utility. Lastly, further documentation may be found here.
C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.1.7600.16385_none_c9392808773cd7da\cleanmgr.exe > %systemroot%\System32

You may use the following Microsoft Windows PowerShell cmdlet to view the last one hundred lines of a Microsoft Windows Server DHCP server log for a particular Internet Protocol (IP) address. This may be useful when you are troubleshooting DHCP errors in Microsoft Windows Server.
Get-Content DhcpSrvLog-Mon.log | Select -Last 100 | Select-String -Pattern “X.X.X.X” -encoding ASCII
You may use the Resolve-DnsName Microsoft Windows PowerShell cmdlet to perform Domain Name System (DNS) query resolution for the domain name(s) you specify. Below you will find a few examples of this cmdlet.
To perform a standard query enter Resolve-DnsName domain.com.
To perform a query without the use of a local hosts file or DNS cache enter Resolve-DnsName domain.com -NoHostsFile.
To perform a query only using the DNS client cache enter Resolve-DnsName domain.com -CacheOnly. NOTE: In this example, the DNS client cache is cleared, first. Therefore, the error is expected.
To perform a query while specifying a particular DNS server enter Resolve-DnsName domain.com -Server X.X.X.X.
To perform a query for a specific DNS record enter Resolve-DnsName domain.com -Type XX.
To perform a query of multiple domains enter “domain.com“,”domain.com“,”domain.com” | Resolve-DnsName. 
To perform a query of domain names using a file enter Get-Content file | Resolve-DnsName. NOTE: I do not recommend placing the file in the C:\Windows\System32 directory. However, I used that directory in this example for simplicity.
