Yep, those MTUs. Because inconsistent RPC fragmentation can cause transactions to fail.

As in TCP/IP Maximum Transmission Units? I will check that and post back, but why would a mismatch in MTU show up as this? Kurt On Mon, Jul 24, 2017 at 5:31 AM, Michael B.

I've overcome some blindness on my part, and have a bit more information, though I fear it's not enough.

The US has a bunch of directories that will be replicated to AU (but not back). No big deal, but the PowerShell script I'm writing is killing me. I don't know if I'm running into a time out problem, or what it might be. I'm running the script from Redmond on my laptop. Here's the script, which should Just Work(tm): ---------- $NewDFSR = import-csv -Delimiter "`t" c:\Batchfiles\data\NewDFSR.csv New-DfsReplicationGroup -GroupName US2AU-Engineering $GroupName = Get-DfsReplicationGroup US2AU-Engineering Foreach ($Line in $NewDFSR) { $GroupName = $Line.GroupName $SourceComputer = $Line.SourceComputer $FolderName = $Line.FolderName $SourceContentPath = $Line.SourceContentPath $SourceStagingPathQuotaInMB = $Line.SourceStagingPathQuotaInMB $SourcePrimaryMember = [System.Convert]::ToBoolean($Line.SourcePrimaryMember) $DestinationComputer = $Line.DestinationComputer $DestinationContentPath = $Line.DestinationContentPath $DestinationReadOnly = [System.Convert]::ToBoolean($Line.$Line.DestinationReadOnly) New-DfsReplicatedFolder -GroupName $GroupName -FolderName $FolderName Add-DfsrMember -GroupName $GroupName -ComputerName $SourceComputer, $DestinationComputer Add-DfsrConnection -GroupName $GroupName -SourceComputerName $SourceComputer -DestinationComputerName $DestinationComputer Set-DfsrMembership -GroupName $GroupName -FolderName $FolderName -ComputerName $SourceComputer -ContentPath $SourceContentPath -PrimaryMember $SourcePrimaryMember -StagingPathQuotaInMB $SourceStagingPathQuotaInMB -Force Set-DfsrMembership -GroupName $GroupName -FolderName $FolderName -ComputerName $DestinationComputer -ContentPath $DestinationContentPath -ReadOnly $DestinationReadOnly -Force } ---------- But it fails the Add-DfsrMember command, when trying to add the AU file server: ---------- Add-DfsrMember : Could not add the computer to the replication group.
