Powershell script to know which Server it logged on and applications installed

Hi, i need assistance to write a powershell script and output it in CSV file, the script will interrogate AD to get computers information from a specific OU, and find out from that OU the computers last login time stamp, location based on IP and applications installed on each computer.

Here is a first version, you didn't specify if you want a different file per computer or if you want it all together in one CSV.

You will need to modify the If and ElseIf Statements to add all of your IP ranges and Location Names

$results = @()
Get-ADComputer -filter * -SearchBase "CN=Computers,DC=domain,DC=com" -Properties Name,IPv4Address,lastlogonTimestamp | 
% {
if($_.IPv4Address -match "10.9.") { $location = "Site 1" }
ElseIf($_.IPv4Address -match "10.8."){ $location = "Site 2" }
ElseIf($_.IPv4Address -match "10.7."){ $location = "Site 3" }
Else { $location = "Unknown"}
$timestamp = [DateTime]::FromFileTime($_.lastlogonTimestamp)
$name = $_.Name
$results += Get-WmiObject -Class Win32_Product | Select @{Name="Computer Name";Expression={$name}},@{Name="Application Name";Expression={$_.Name}},@{Name="LastLogon";Expression={$timestamp}},@{Name="Location";Expression={$location}}
  }
$results | Export-Csv "C:\Applications Installed.csv" -nti

A different  file for each computer, and the computer information  is retrieved from a specific OU in AD.

and can you please clarify me the expressions in parenthesis "".
if($_.IPv4Address -match "10.9.") { $location = "Site 1" }
ElseIf($_.IPv4Address -match "10.8."){ $location = "Site 2" }
ElseIf($_.IPv4Address -match "10.7."){ $location = "Site 3" }
Else { $location = "Unknown"}

In your post you said you wanted location based on IP so that is for you to put in your IP subnet for each site and give it a name.

For example, all IPs that start with "192.168.1" are in New York, all that start with "192.168.2" are in Sacramento, etc

if($_.IPv4Address -match "192.168.1") { $location = "New York" }
ElseIf($_.IPv4Address -match "192.168.2"){ $location = "Sacramento" }
ElseIf($_.IPv4Address -match "10.7."){ $location = "Site 3" }
Else { $location = "Unknown"}

If you need more/less just add/remove the ElseIf($_.IPv4Address -match "10.7."){ $location = "Site 3" } line for each site and fill in the details.

If you want to just have the IP Address instead of the "Site" use this.

$results = @()
Get-ADComputer -filter * -SearchBase "CN=Computers,DC=domain,DC=com" -Properties Name,IPv4Address,lastlogonTimestamp | 
% {
$timestamp = [DateTime]::FromFileTime($_.lastlogonTimestamp)
$name = $_.Name
$ipaddress = $_.IPv4Address
$results += Get-WmiObject -Class Win32_Product | Select @{Name="Computer Name";Expression={$name}},@{Name="Application Name";Expression={$_.Name}},@{Name="LastLogon";Expression={$timestamp}},@{Name="IP Address";Expression={$ipaddress}}
  }
$results | Export-Csv "C:\Applications Installed.csv" -nti

If you want to add the IP Address also, use this.

$results = @()
Get-ADComputer -filter * -SearchBase "CN=Computers,DC=domain,DC=com" -Properties Name,IPv4Address,lastlogonTimestamp | 
% {
if($_.IPv4Address -match "10.9.") { $location = "Site 1" }
ElseIf($_.IPv4Address -match "10.8."){ $location = "Site 2" }
ElseIf($_.IPv4Address -match "10.7."){ $location = "Site 3" }
Else { $location = "Unknown"}
$timestamp = [DateTime]::FromFileTime($_.lastlogonTimestamp)
$name = $_.Name
$ipaddress = $_.IPv4Address
$results += Get-WmiObject -Class Win32_Product | Select @{Name="Computer Name";Expression={$name}},@{Name="Application Name";Expression={$_.Name}},@{Name="LastLogon";Expression={$timestamp}},@{Name="Location";Expression={$location}},@{Name="IP Address";Expression={$ipaddress}}
  }
$results | Export-Csv "C:\Applications Installed.csv" -nti
