Server Decommission Audit

Recently one of the IT team approached us to create a script where they want to audit if the decommissioned servers in the environment have entries in Active directory, DNS, WINS & also to check the ping status. Their approach was to find any discrepancies.

So this script has taken birth 🙂 , I am sharing it as it would be useful in other environments as well.

For checking entry in AD , I have used Quest AD management Shell. Get-Qadcomputer

For checking in DNS , I have used Nslookup. nslookup -querytype=A $_ 2>&1

For checking in WINS , I have used Nblookup. .\nblookup $_

Nblookup can be downloaded from below link, although I have included it inside the script folder. (as it would be used from same path)

https://support.microsoft.com/en-us/kb/830578

Lastly I have used Test-Connection for checking Ping status.

Extract the zip file from below link, update the srv.txt file & variables smtp inside .ps1

https://github.com/VikasSukhija/Downloads

$smtpserver = “smtpserver”

$from = “DecomSrvAudit@labtest.com”

$to = “vsukhija@labtest.com

Run the batch file & report will be sent to email id defined inside the script.
