Last night i was deploying a DPM server for a customer and we needed to deploy the DPM agent on a few machines. It is well know that DPM can do push agent install, but the requirements is to open high ports on every client, well lets state that it is not something any customer likes to do, so that means that we will use the Attach Agent function in DPM and that require the agent to be installed first.
The trick is not to install it, rather running the setDpmServer command that will do a connection against the DPM server, resulting in the double hop issue in Windows. The real solution is to use the existing software deployment solution to push the agent or to install the agent when the server is deployed, but in this case we needed a quick-and-dirty method to get it out to a few servers.
So the script will copy the installers to the target, install the agent, configure the agent and add the agent to the DPM server. It works with multiple servers at the same time. It uses CredSSP to fix the double-hop issue, which was ok for this customer.
The Script
Param(
$Servers,
$UserName,
$Password,
$DMPServerName
)
$SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force
$User = “$env:USERDOMAIN\$UserName”
$Credentials = New-Object System.Management.Automation.PSCredential -ArgumentList $User, $SecurePassword
Foreach($Server in $Servers){
Enable-WSManCredSSP -Role Client -Force -DelegateComputer $Server
New-Item -Path "\\$Server\c$\DPMinstall" -ItemType Directory -Force
Copy-Item -Path 'C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\ProtectionAgents\RA\4.2.1205.0\amd64' -Destination "\\$Server\c$\DPMinstall" -Container -Force -Recurse
Invoke-Command -ComputerName $Server -ScriptBlock {
Enable-WSManCredSSP -Role Server -Force
cmd.exe /c C:\DPMInstall\amd64\DPMAgentInstaller_x64.exe /q /IAcceptEula
& 'C:\Program Files\Microsoft Data Protection Manager\DPM\bin\SetDpmServer.exe' -dpmServerName $DMPServerName
} -EnableNetworkAccess -Credential $Credentials -Authentication Credssp

}
