List DFS replication groups:
dfsradmin rg list
List replicated folders in a replication group:
dfsradmin rf list /rgname:<REPL_GROUP>
List members of a replication group:
dfsradmin mem list /rgname:<REPL_GROUP>
List the local folders that correspond to replicated folders of a replication group:
dfsradmin membership list /rgname:<REPL_GROUP> /attr:RfName,MemName,LocalPath
Show backlog between 2 members of a replication group:
dfsrdiag backlog /rgname:<REPL_GROUP> /rfname:<REPL_FOLDER> /smem:<SRV_A> /rmem:<SRV_B> [/v] dfsrdiag backlog /rgname:<REPL_GROUP> /rfname:<REPL_FOLDER> /smem:<SRV_B> /rmem:<SRV_A> [/v]
dfsrdiag can also be used for inspecting SYSVOL backlog when DFS-R SYSVOL replication is enabled:
dfsrdiag backlog /rgname:"Domain System Volume" /rfname:"SYSVOL Share" /smem:DC1 /rmem:DC2
A word of warning if you want to run commands like the one above in PowerShell: parameters with spaces are a major pain in the rear. Naïve approaches like
& dfsradmin rf new /rgname:MyGroup /rfname:"My Replicated Folder"
or
& dfsradmin rf new /rgname:MyGroup "/rfname:My Replicated Folder"
or
& dfsradmin rf new /rgname:MyGroup "/rfname:`"My Replicated Folder`""
or even
$cmd = 'dfsradmin.exe'
$params = @('rf', 'new', '/rgname:MyGroup', '/rfname:"My Replicated Folder"')
& $cmd $params
won’t work, regardless of what recommendations you may find on the Internet. You need to work around this issue like this:
$env:rgname = 'MyGroup' $env:rfname = 'My Replicated Folder' & cmd /c 'dfsradmin rf new /rgname:%rgname% /rfname:"%rfname%"'
or (slightly more PoSh) like this:
$rgname = 'MyGroup'
$rfname = 'My Replicated Folder'
& cmd /c ("dfsradmin rf new /rgname:{0} /rfname:`"{1}`"" -f $rgname, $rfname)
In PowerShell v3 you could also do this:
$env:rgname = 'MyGroup' $env:rfname = 'My Replicated Folder' & dfsradmin --% rf new /rgname:%rgname% /rfname:"%rfname%"

First start by forcing the creation of your PowerShell ISE profile file if it doesn’t exist
if (!(Test-Path -Path $PROFILE ))&lt;br&gt;<br><br>
{ New-Item -Type File -Path $PROFILE -Force }
Second, within your ISE console, type the following
psEdit $profile
In the script pane, just copy/paste the below blue script
$StopWatch = [System.Diagnostics.StopWatch]::StartNew()
Function Test-Command ($Command)
{
Try
{
Get-command $command -ErrorAction Stop
Return $True
}
Catch [System.SystemException]
{
Return $False
}
}
IF (Test-Command "Get-Mailbox") {Write-Host "Exchange cmdlets already present"}
Else {
$CallEMS = ". '$env:ExchangeInstallPath\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto -ClientApplication:ManagementShell "
Invoke-Expression $CallEMS
$stopwatch.Stop()
$msg = "`n`nThe script took $([math]::round($($StopWatch.Elapsed.TotalSeconds),2)) seconds to execute..."
Write-Host $msg
$msg = $null
$StopWatch = $null
}

Removes spam from exchange 2010 with powershell. Creates a log file in
G:\s\Logs\exchange\
Edit the $spam var.
Use “from:$spam” for From and “subject:$spam” for Subject.
$spam = "pravinchauhan1991@yahoo.in"
$today = (get-date).tostring("MM-dd-yyyy")
$ExDBs = "db04","db08","db12","db16","db20","db24","db28"
Foreach($ExDB in $ExDBs)
{
#Defines source and destination
$outfile = 'G:\s\Logs\exchange\SpamCleanUp_' + $today + '_' + $spam + '_' + $ExDB + '.txt'
