DFSR - Setting MaxOfflineTimeInDays resets RPC port

Question

I am using Windows Server 2016 and am attempting to set the DFSR attribute MaxOfflineTimeInDays. The script line I am using is resetting the static RPC port I have set. To set the static RPC port I used the following cmdlet set-dfsrserviceconfiguration -rpcport <static rpc port number> I checked this using both get-dfsrserviceconfiguration and get-ciminstance -namespace root/microsoftdfs -query "select * from dfsrmachineconfig" I could not find a powershell cmdlet to set the maxofflinetimeofdays so I then run the following command to set the attribute set-ciminstance -namespace root/microsoftdfs -query "select maxofflinetimeindays from dfsrmachineconfig" -property @{maxofflinetimeindays=180} This has the side effect of resetting the RPCPort to 0 and setting the DynamicRPCPort to false in output from get-dfsrserviceconfiguration Conversely, using the command set-ciminstance -namespace root/microsoftdfs -query "select rpcportassignment from dfsrmachineconfig" -property @{rpcportassignment=<staticrpc port number} results in the maxofflinetimeindays being reset to the default (60 in my case) Using the command wmic.exe /namespace:\root\microsoftdfs path dfsrMachineConfig Set MaxOfflineTimeInDays=180 does not result in the RPCPort being reset so I do have a way forward Any thoughts?

Start > Run > cmd > Type the following command:

"wmic.exe /namespace:\\root\microsoftdfs path DfsrMachineConfig set MaxOfflineTimeInDays = 999"

Verify the MaxOffline attribute has changed successfully to 999. Type the following command:

"wmic.exe /namespace:\\root\microsoftdfs path DfsrMachineConfig get MaxOfflineTimeInDays"

Note: Remove the quotes.

$dfsrPath = Get-WmiObject -Namespace root\microsoftdfs -Class DfsrMachineConfig
$currentValue = $dfsrPath.MaxOfflineTimeInDays
$requiredValue = "999"

if(!($currentValue -eq $requiredValue)){
        Write-Host "Required value does not exist"
        Write-Host "Current value: $currentValue"
        Write-Host "Required value: $requiredValue"
        Write-Host -Verbose "Going to set MaxOfflineTimeInDays value"
        Set-CimInstance -namespace root/microsoftdfs -query "select maxofflinetimeindays from dfsrmachineconfig" -property @{maxofflinetimeindays=$requiredValue}

 }
else{

        Write-Host "The value of MaxOfflineTimeInDays already Exists. No Action Required"
        Write-Host "Current value: $currentValue"
        Write-Host "Required value: $requiredValue"
}
