Windows DFSR Troubleshooting

A few cmds to help with the DFS troubleshooting aspects, keep in mind all should be run from an elevated PowerShell
Dfsdiag /TestDCs

DFSDiag /TestDFSIntegrity /DFSRoot:\\Contoso.com\MyNamespace /Recurse /Full

Dfsutil /pktinfo

Dfsutil /spcinfo

Dfsr pollad

Klist tgt

Klist tickets

DfsrAdmin Health New /RgName:"Contoso.com\Path1\Folder1" /RefMemName:SERVER /RepName:C:\DFSReports\HealthReport_DATE.html /FsCount:true

dfsrdiag ReplicationState /member:SERVER /all

wmic /namespace:\\root\microsoftdfs path DfsrReplicatedFolderInfo get * /format:textvaluelist

Get-ChildItem C:\Temp -recurse | Out-File E:\DFS-Data\Path1\DfsrPrivate\Staging > C:\Export\allfiles.txt

dfsrdiag backlog /receivingmember:SERVER2 /sendingmember:SERVER1 /rgname:"ReplicationGroup1" /rfname:"Folder Name"

To search for replicated folder name:

1. From Elevated PowerShell: Notepad "C:\Windows\Debug\Dfsr####.log"

2. Find "parent" GUID (will look like {D767AC01-8375-447A-88E4-1CCF6A18DD95}-v167695)

Search for GUID

Run: wbemtest

Namespace: root\microsoftdfs connect

Query: "Select * from dfsreplicatedfolderconfig"

Completely Flush Server

• dfsutil /pktflush
• dfsutil /spcflush
• dfsutil /purgeMupcache
• klist purge
• ipconfig /flushdns 

Delete DfrsPrivate folder

md d:\empty

Robocopy.exe d:\empty "D:\System Volume Information\dfsr\Private" /purge

rd d:\empty
