+    At this point, the DFS Management snap-in (should) be successfully showing all of the DFS namespaces and replication groups when you re-open "DFS Management".
+
+#### Check Replication Progress
+You may want to check that replication is occurring bi-directionally between every member server in your DFS deployment.  I wrote a script below that effectively shows you every replication group and each directional backlog status.
+
+```powershell
+# --- CONFIG ---
+$Members = @("LAB-FPS-01","LAB-FPS-02")
+$SummarizeAcrossFolders = $true  # $true = one line per direction per RG; $false = per-folder lines
+
+function Invoke-DfsrBacklogStatus {
+    param(
+        [Parameter(Mandatory)] [string] $RG,
+        [Parameter(Mandatory)] [string] $RF,
+        [Parameter(Mandatory)] [string] $Send,
+        [Parameter(Mandatory)] [string] $Recv
+    )
+
+    $out = & dfsrdiag backlog /rgname:"$RG" /rfname:"$RF" /sendingmember:"$Send" /receivingmember:"$Recv" 2>&1 | Out-String
+    $outTrim = ($out -split "`r?`n" | ForEach-Object { $_.Trim() }) | Where-Object { $_ -ne "" }
+
+    if ($out -match 'No Backlog') {
+        return [pscustomobject]@{ Status="No Backlog"; Count=0; Detail=$null }
+    }
+
+    $count = $null
+    $countLine = $outTrim | Where-Object { $_ -match '(?i)backlog' } | Select-Object -First 1
+    if ($countLine -and ($countLine -match '(\d+)')) { $count = [int]$matches[1] }
+
+    $detail = ($outTrim | Select-Object -First 8) -join " | "
+
+    return [pscustomobject]@{
+        Status = if ($count -ne $null) { "Backlog: $count" } else { "Backlog/Check Output" }

+                    }
+                }
+            }
+        }
+    }
+}
+```
+
+!!! example "Example Output"
+    You will see output like the following when you run the script.
+
+    ```powershell
