FRS and DFS-R

Hello There,
We have a following FRS registry entry on Win 2003 DCs
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet
Ports: REG_MULTI_SZ: 5101-5200
PortsInternetAvailable: REG_SZ: Y
UseInternetPorts: REG_SZ: Y
We are migrating from Win 2003 to Win 2012 R2 and have configured the above registry and the following, on win 2012 R2 DCs.
DFSRDIAG STATICRPC /port:5100
Will the FRS and DFS-R conflict for port?.

Hi,
From the description they will not conflict for ports.
However if there is no Windows 2003 systems in your environment now, FRS is not needed anymore. By default from Windows 2008 R2, AD will also be replicated via DFSR instead of FRS.
In Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2, FRS can be used only to replicate the SYSVOL folder on domain controllers in domains that use the Windows Server 2003 or Windows 2000 domain functional levels.
See: FRS Overview

BSOD on Server 2012 running dfs namespace and dfs replication roles with deduplication

Hello,
I have recently setup 2 dfsn & dfsr servers, both 2012 one physical the other virtual.
The idea is to have one server as primary and the other as a failover \ DR.
The primary server is virtual and connects via mpio \ iscsi to a dell san, using the provided dell DSM Drivers.
The secondary server is physical with local disk for storage.
I copy files to a namespace setup to always prefer the primary server, these files are then replicated across to the secondary.
I have also turned on deduplication on both servers to get the most out of the available storage.
This has been working well for 6 months or so, there have however been 2-3 occasions where the primary virtual server has crashed and blue screened causing the DFSR database to undergo a full consistency check.
The bug check errors i have managed to extract from the Memory.dmp and mini dump are as follows:
*                        Bugcheck Analysis
REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
Arg2: fffffa80379a3070, Object whose reference count is being lowered
Arg3: 0000000000000002, Reserved
Arg4: ffffffffffffffff, Reserved
   The reference count of an object is illegal for the current state of the object.
   Each time a driver uses a pointer to an object the driver calls a kernel routine
   to increment the reference count of the object. When the driver is done with the
   pointer the driver calls another kernel routine to decrement the reference count.
   Drivers must match calls to the increment and decrement routines. This bugcheck
   can occur because an object's reference count goes to zero while there are still
   open handles to the object, in which case the fourth parameter indicates the number
   of opened handles. It may also occur when the object?s reference count drops below zero
   whether or not there are open handles to the object, and in that case the fourth parameter
   contains the actual value of the pointer references count.

I have searched for others having a similar problem but have not managed to find much.
The memory dump at the time of the crash does seem to hint at a problem with DFSR.exe.
The setup seems to be running fine again now and is going through its consistency checks, it is just a major inconvenience and will only get worse as the DFS becomes busier and approaches capacity.
The plan was to put this setup into production however with the unpredictability of blue screen reboots I cannot see this happening until I can find a fix or work around.
I have yet to see this problem occur on the other (physical) server, this is pretty much identical in configuration apart from its storage access.
My thoughts are a possible bug in the DFSR component or a bug in the DSM Drivers used for the iSCSI SAN connection or maybe a combination of the two.
Any help, thoughts or suggestions greatly appreciated
Thanks

Hi,
Please install the current version of Dfssvc.exe Dfsc.sys Dfsrs.exe for Windows Server 2012.

The issue may be due to the DFSRoot folder has lost NTFS permission. Some reasons why DFS root lose ACLs Links are listed in the article below:

To narrow down the issue, you could remove the DFS role to check if the issue related to the dfs namespace and dfs replication roles.

Generating and updating URS, FRS and test

Hi folks,
I am trying to find some material in this regard i wanna know what is generating and updating URS, FRS and test script documents
Pls anyhow help me its very urgent
Thanks in advance and waiting for u r answer
prasad

Hi,
More information about the issue....
We are creating the test scripts both manual and automated.
Manual
Using the Tx. STWB_TC, we are creating the manual test cases. While doing so we will provide the test case desctiption
Automated ECATT
using the Tx. SECATT, we are creating the Test Configuration. We are providing description through the documentation option.
The SAP format for both documents is
               &DESCRIPTION&
               &PREPARATION&
               &ENTRANCE&
               &REALIZE&
               &CHECK&
               &FURTHER_HINTS&
But we want the format to be
               <DESIGNSTEPS>
               <INPUTDATA>
               <EXPECTEDRESULT>
               <TARGETSYSTEM>
So we want to update the format / template to reflect the changes.
Please guide us to do so.
Thanks and Regards

In-place Upgrade Server 2012 to R2 running DFS-N and DFS-R roles

Hello,
I have 2 servers running DFS-R and DFS-N running Windows Server 2012. I am planning to do an in-place upgrade to 2012 R2. Is this supported?
Rgds,
Irfan
Irfan Goolab SALES ENGINEER (Microsoft UC) MCP, MCSA, MCTS, MCITP, MCT

Hi Irfan,
Yes, you can upgrade Windows Server 2012 to 2012 R2 to deploy a later version of DFSR. DFSR must be recreated for that server and perhaps for the entire Replication Group depending on the server’s place in data origination.
For more detailed information, please refer to the articles below:

FRS and DFSR replication

Hi all,
fase 1
My domain controllers are both Windows 2003 R2 and Windows 2008 and Windows 2008R2. Domain functional level is Windows 2003
fase 2
I upgrade all my domain controllers to Windows 2008R2 and raised the domain functional level to Windows 2008R2.
Now do domain controllers replicate via DFS-R? Have I to make some operation to get all replication works via DFS-R?

Hi,
Domain controllers use a special shared folder named SYSVOL to replicate logon scripts and Group Policy object files to other domain controllers. Windows 2000 Server and Windows Server 2003 use File Replication Service (FRS) to replicate SYSVOL, whereas
Windows Server 2008 uses the newer DFS Replication service when in domains that use the Windows Server 2008 domain functional level, and FRS for domains that run older domain functional levels.
To use DFS Replication to replicate the SYSVOL folder, you can either create a new domain that uses the Windows Server 2008 domain functional level, or you can use the procedure that is discussed in this document to upgrade an existing domain and migrate
replication to DFS Replication.
There are many helpful articles for you to refer to to migrate sysvol replication form FSR to DFSR. Please refer to the below link to find a article you want to follow:

Multiple Forest DNS queries, and DFS

Setup:
2 physical servers hosting several virtual machines with 3 forests (domains) and 3 subnets. The physical server has 4 NICs, each forest/subnets has its own dedicated NIC via virtual switch (so 1 NIC is empty). Each NIC connects to a switch to
allow workstations and other devices to connect to their proper forest/subnet directly. These switches then connect to the sonicwall (firewall/router) in an individual port. Each port has proper subnet defined in it.
The 3 forests are c.com, l.lan, and w.web named. c.com and l.lan use a 10.x.x.x/255.255.0.0 subnet. w.web uses 192.168.x.x/255.255.0.0 subnet. There are no trusts setup.
I can ping from one forest/subnet to the other using IP address without issue so the IP routes are fine. I can ping via FQDN without issue if I setup a forwarder, conditional forwarder, or stub zone. Sometimes using just the forwarder, FQDN does
NOT resolve. Conditional and Stub seems to resolve always.
I can get c.com and w.web to resolve single-name (host name) addresses, but at the moment (transitioning) they are on the same subnet. From some research, I can use single-name resolution if I setup a GlobalNameZone as well, which I might need to do.
So my question is which is best practice and most reliable way to setup these different forests and subnets to perform DNS resolution? I tried forwarders, but it wasn't always reliable. I suspected caching as an issue, but after a flush, a FQDN
would sometimes resolve and sometimes not. Conditional and Stub seem to work okay, but I'm not sure about what's best.
I've spent most of the day researching this, and nothing was every really definitive and sometimes even contradictory. Previously the DNS Forwarders worked fine for us, but that was on the same subnet. Differing subnets seems to break the internal-to-internal
forwarding.
Additionally the w.web domain has a domain level DFS. Neither of the other forests can access it via the
\\w.web\data address. Though they can access it if I point them directly to the server hosting the DFS namespace.

Windows Server doesn't work well with DNS Search Suffixes defined in DHCP scopes from what I read.

Details how to set it up on Windows Server DHCP
http://social.technet.microsoft.com/Forums/en-US/2eed4d4f-8d1b-4989-ac49-d95e08b7d54a/dhcp-dns-suffix-search-list-supported?forum=winserverNIS
Details how Windows Server does not support it though.
http://technet.microsoft.com/en-us/library/bb847901(v=exchg.150).aspx
Details how to use Group Policy to deploy it.
How I fixed this:
1) Open Group Policy for the domain.
2) Edit the "Default Domain Policy" to include DNS Suffix search for current domain and all other domains.
3) Set normal forwarders on domain's DNS servers.
4) Repeat on all domain.
This partially fixed my problem. Things were resolving more reliably, but there would be a failure once in a while as well. I corrected this by adding a conditional forwarder along with the normal forwarder.
Now I get full resolution of all items. Additionally, I do not have to use the FQDN for my machines. Just hostname resolves just fine. HOWEVER I would suggest to anyone setting up machines to use FQDN where possible, don't be lazy.
This means I will not have to setup a GlobalName zone either. Though I may do it for the experience.
Another problem though is this only works on Windows machines. Mobile phones (such as Android and iPhone) and other such devices will not know about the DNS Suffix search. Fortunately most of those devices required the internet FQDN for services
to work anyway, and when behind the firewall via WiFi or like, they'll be able to still resolve the internet FQDN of devices since we're using a split-brain DNS for that domain.

Slow file browsing in MED-V / XP Mode with NAT and DFS

Note, for the purposes of this question, this issue is with the Windows Virtual PC / XP Mode integration portion of MED-V so is not MED-V specific.
We are in the process of deploying hundreds of MED-V instances to Windows 7 PCs to support legacy applications until they are replaced with versions that are compatible with Windows 7. Due to security concerns and our network infrastructure configuration,
we are required to use "Shared Networking (NAT)" mode for the Windows XP virtual machines. Our network drives are mapped to DFS shares. Depending on the site and drive mappings of a user, when opening or saving a file in an application,
it can take several minutes to browse to the target directory, even if it's not on a DFS share. Occasionally, it takes so long that the RemoteApp window hangs and disappears, even though the application is still running in the Windows XP VM.
Running network traces in the VM, I can see that Windows XP tries to "ping" all of the DFS targets whenever the network drives are enumerated, such as when clicking on My Computer. It waits for responses, then eventually times out.
From what I understand, this is the way that Windows XP determines which DFS target link is the fastest. Unfortunately, since vpc.exe does not run with admin rights in Windows 7, ICMP (ping sends ICMP ECHO REQUESTS) is blocked by the NAT
between the VM and the Windows 7 host. (This is why you cannot ping other PCs on the network from within the Windows XP VM when using NAT.) Therefore, the long wait times happen while XP waits for the replies that never come.
To verify that this is indeed the problem, I started vpc.exe with admin rights, then started the MED-V Workspace. I could ping other computers now from within XP and browsing took seconds instead of minutes. However, our users will not have admin
rights in Windows 7 so this is not an option for them. I also tested in bridged mode instead of Shared Networking mode with the same positive results. However, this is also not an option in our environment.
Any solutions or recommendations will be greatly appreciated.
Thank you in advance,

Microsoft Office and DFS namespace

Hey guys
We recently switch our folder redirection to a DFS server and now we have users experiencing "Trying to Connect to domain.local
and I don't think its an error more just a visual message but is there anything we can do to disable or fix the issue? We have Windows 7 Clients w/ Office 2010 and Windows 8 Clients w/ Office 2013 both experiencing it when the Click on "Open" or
"Save in the application.

Hi,
I think it is caused that Office consider the \\domain.com\root\folder is a place like an internet location (which is normal to me that Office does not know about DFS) and I assume it is the default behavior of Office for displaying "connect to xxx"
while opening or saving files from/to an internet location.
I confirmed with Office engineer about disabling it but there is no such option in Office. You could post a thread to Office forum for further information about it:

User Profile Disks and DFS replication

We're looking to replace a single, heavily used 2003 TS server--for performance, feature, and capacity reasons. Our users frequently have small amounts of data on their desktops/settings that we'd to persist between sessions, and they tend to have
long-running sessions (disconnecting and reconnecting while traveling, but not logging off--keeping open apps in the meantime).
The servers were originally purchased intending for 2008R2 SP1 remote desktops services, with lots of fast internal (RAID 5, 12x300GB 15K) storage. We're considering the option of using 2012 (virtual sessions, not virtual desktops) so that we can scale
out as we grow--and use the User Profile Disks.
Ideally, we'd like to maximize the usefulness of the purchased servers (and their internal storage), and not have to purchase additional hardware for shared storage--(iSCSI/External array that can be clustered). We're wondering if it's possible to pair
the User Profile Disks (UPD) with DFS replication (possibly over a dedicated NIC). Then, a user could log in to server X, connect to her local UPD (with the changes replicating to server Y's copy). If she disconnected/reconnected, the RD connection broker
would connect her to back to her existing session, and if she logs off and back on, she could connect to either server X or Y and it would all work. For maintenance, we'd be able to drainstop one server via the connection broker, perform the maintenance,
let DFS catch up, and then do the same on the second server.
Would something like this be possible? Or is it just asking for major problems?

Hi,
Thank you for your question.

Offline Files and DFS-R (Windows 7 and Server 2008 R2)

Hey,
We are planning to migrate from full roaming profiles to folder redirection instead.
I am testing this at the moment and one thing that's happening is we're getting Sync Errors on the clients. The weird thing is that the errors come from folders that aren't even available offline (set on the Caching tab within the Advanced Sharing
tab on the server).
So the only folder available for Offline use is:
\\corp.domain.com\dfsnamespace\Users
But the sync errors are reporting these:
\\corp.domain.com\dfsnamespace\Public\Templates\...
\\corp.domain.com\dfsnamespace\Public\Resources\...
etc. The Details column shows 'The request is not supported.'
So it seems it's trying to sync any folder in the dfs root folder (\\corp.domain.com\dfsnamespace\*). And I assume 'the request is not supported' error comes up because the folder is not actually available for offline use.
How do I stop this?

Hi,
Do you configure “Always available offline” on the clients? If so, disable it to check if the issue still exists. The Offline Files feature must be enabled on the client computer for files and programs to be automatically cached. Additionally, the
Optimized for performance option does not have any effect on client computers using Windows Vista or newer.
For more detailed information, please refer to the articles below:

WAAS and dfs

Hi,
is there anybody firm in configuring WAAS with Microsoft dfs?
We have two WAE managed by Cantral Manager. Under File Services > Prepositions we want to configure dfs.
Can we configure a specific domain like xxx.yyy instead of a specific file server address?
Best regards

As a follow up to this questions. The customer currently has large file servers in their remote branches. They manually copy what files they need from one branch to another. I am planning on recommending a 274 appliance in this case due to the low number of users they have at each site. I have a couple questions though:
1. Cisco does not publish how many peers the 274 will support. Will this small of a box only work in a point to point configuration? What about customers that have any to any connectivity requirements over an MPLS WAN?
2. The 274/474 only support up to 35GB of HD space for the VB. If we were only to run Windows 2008 Core Server, would that much space be adequate for an AD/DHCP/DNS/Print Server in most cases even after updates? Do you have any idea on the storage requirements for MS 2008 servers on a virtual blade? Will 1GB be enough?
These are small sites and I don't want to undersize them from a VB or site to site standpoint.
What do you recommend?

Indesign and DFS share problems.

Hi,
Sorry for the long post, but I need you.
We are currently deploying over 40 Windows 7 workstation here at my job. We've been dealing with an issue for the past 2 weeks that has completely stopped the deployment.
Before I go into the problem let me give you an overview of our infrastructure. Because of the necessity of having high availability of the information we have a DFS Share that replicate the information on two different physical location. People here work directly on this shared drive, which guarantee them that the work they do is backed up and distributed everywhere all the time. On top of that it also prevent people from working on the same file by locking it when it is open by someone else.
The problem is whenever we try to work with document located on this shared drive, InDesign will periodically crash. If we work from another shared drive with no DFS, there is no problem. Under Windows XP we never had this problem, but with Windows 7 it's currently impossible. We have currently InDesign CS5.5, but we also tried InDesign CC and it does the same thing.
Simple scripting command like .saveACopy() will crash the application guaranteed. I know this is not a Scripting Forum, but using the same Save A Copy from the file menu will result in the same thing. Other scripts will sometime complain that the object is no longer available, again something that we don't experiment when working on other shared drives that don't have DFS.
Have anyone experimented this? Is this a known problem? Anyone have a solution to work with DFS share?
Thank you.

What's DFS share?
DFS stand for Distributed File System.
It basically allow replication of data across multiple servers and provide multiple access point to the information depending on various factor (server load, location, etc.) You can read more about it here. https://en.wikipedia.org/wiki/Distributed_File_System_(Microsoft)
Have you fully patched InDesign (Help>Updates) and have you fully patched your share drive/server side?
Indesign CS5.5 is at 7.5.3. DFS was updated this week, but it didn't fix it. Our production environment is completely cut off from the internet, because of the sensitivity nature of the information we deal with until it's published.
Is this on the same file or all files?
Does it happen on Newly created files or just on older files or all files no matter what?
It's happening with new file or already created one, with or without our template.

FSRM [Source File Path] and DFS

Hi,
When i use the [Source File Path] in a notification email it does not show the source file path but instead shows d:\xxxx which is the local drive of the server hosting the destination share.
The users has a lot of problems with file types that are not allowed. But i can't find a good way to show them the file that has been blocked with out showing them the local server drives or shares and this is not a good way.
Any suggestions to what could be done so i can show the users what files have been blocked?

Hi,
I get the reply from FSRM Discussions team.
The source file path in this case does not relate to the copy operation (FSRM has no clue where this is copied from) – rather to the location of the file that caused the problem.
If the path for the file that caused the notification is a shared folder or volume, we can use [Source File Remote Paths] instead of [Source File Path] to insert the path in UNC format (\\Server\Share\).

Mandy

Keeping CMS database and FRS backups in synch

I am in the process of upgrading to BOE XI R3.1 from CE 10 and am looking at our backup and recover plan.
We are planning on implementing 2 BOE Xi R3.1 servers with a clustered CMS. Our CMS database will be running on a remote SQL Server (2005) farm that will be immediately replicated to our secondary site using SRDF.
The FRS will be local to each BOE XI R3.1 server. We are thinking of immediately replicating the FRS from the primary location to the secondary location using DFS but I worry about the FRS and the CMS possibly being out of synch when we try to restore.
By trying to have backups up to the latest instant am I looking for trouble? if this is manageable, am I going about it the right way?
In our CE 10 deployment we have a CMS database backup at midnight and the FRS is Robocopied at 12:15. I'm just looking to improve upon this.
Thanks

Right both BOE servers will point to the FRS on the primary BOE server and the primary CMS database on the SQL server farm. Then we replicate the primary FRS to the secondary FRS located on the secondary BOE server and the primary CMS database to the secondary CMS database both on the SQL Server farm.
If we need to we'll switch the primary and secondary BOE servers to the secondary FRS (located on the secondary BOE server) and the secondary CMS database on the farm.
I guess what I'm looking for is the best practice for the backup. I think what I'm hearing is the best route to go is to have the backups as often as you want but the best way to ensure that the backups are in synch is to do them when the CMS and FRS servers are down. Otherwise they could be out of synch with report requests being executed at the same time.
Right?
Thanks again
