Send e-mail with powershell

 Create a file with ps1 extension, like send_mail.ps1, with this content:

# Make Windows negotiate higher TLS version:
[System.Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Send-MailMessage -From from@example.com -To to@example.com -Credential (Get-Credential) -Subject "Hello World" -Body "Your text here" -SmtpServer "smtp.office365.com" -Port 587 -UseSsl 

 

 With cred:

# Make Windows negotiate higher TLS version:
[System.Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential ("username", $secpasswd)
$EmailTo = "myself@gmail.com"
$EmailFrom = "me@mydomain.com"
$Subject = "Test"
$Body = "Test Body"
$SMTPServer = "smtp.gmail.com"

Send-MailMessage -From $EmailFrom -To $EmailTo -Credential $Cred -Subject $Subject -Body $Body -SmtpServer $SMTPServer -Port 587 -UseSsl

Example for english Windows 7, Server 2008r2 and 10 (but not Windows 8.x or 2008):
Select * from Win32_OperatingSystem WHERE (Caption LIKE 'Microsoft Windows 7%' OR Caption LIKE ‘Microsoft Windows Server 2008 R2%' OR Caption LIKE 'Microsoft Windows 10%’) AND OSLanguage = 1033

Simple Active Directory health test

Dcdiag.exe /v >> c:temppre_dcdiag.txt
This is a must and will always tell you if there is trouble with your DCs and/or services associated with it

Netdiag.exe /v >> c:temppre_Netdiag.txt
This will let me know if there are issues with the networking components on the DC.  This along with the post test also is a quick easy way to ensure the patch I just installed is really installed (just check the top of the log)

Netsh dhcp show server >> c:temppre_dhcp.txt
Some may not do this but I”ve felt the pain of a DHCP server somehow not being authorized after a patch.  This allows me verify the server count and names.

Repadmin /showreps >> c:temppre_rep_partners.txt
This shows all my replication and if it was successful or not.  Just be aware that Global Catalogs will have more info here than a normal domain controller.

repadmin /replsum /errorsonly >> c:temppre_repadmin_err.txt
This is the one that always takes forever but will let you know who you are having issues replicating with.
