Dear folks,

I have a simple question about DFSR configuration.

By default, it seems DFSR uses the "background priority" when replicating data.

However, I have a server where I wish to disable this behavior and have replication run at "Normal Priority" (I have my reasons on this one machine).

I've done some research but came up virtually empty handed. The only thing I found was the "IdlePrioritySupported" DWORD under the HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\{GUID}\{DeviceName}\DeviceParameters\Classpnp. I set this to 0.

However, DFSR still replicated with background priority.

Is there a way to change this?

I have a two-way transitive forest trust between two domains (eg domain a and domain b)

If I map a drive to a domain a based dfs structure from domain b, specifying my credentials from domain a, then it appears to connect ok and will display all the folders I'm authorised for access.

However, if I click on one of those folders, I get a Location is not available dialog box up, which the following text... The network location cannot be reached.  For information about network troubleshooting, see Windows Help."

I've seen articles about it being the PC I'm logging on from that is not authenticating, if this is true, or if not, what are my configuration options.  It must be possible under a trust relationship.

We are creating shadow copies 12 times a day so after 5 days they drop off due to the limitation of 64 total. However, if I look at previous versions of files I see available ones with modified dates much older than 5 days. Some go back months.

Can anyone explain how the system determines how far back in time files can be modified and still be available in previous versions? I thought it was only as far back as the shadow copies but obviously that was incorrect.

All,

Looking for some clarification regarding DFS functionality.  I'm currently in the process of disaster recovery on a DFS system I inherited.  It was never set up correctly to begin with (DFS was configured on an existing data share, then another server added).  Replication was never truly working, in that data placed on Server_A never actually got transferred to Server_B.  The admin who I inherited this from used a combination of robocopy scripts and forced namespace usage to ensure that people actually got served the data they needed... basically a mess.

Anyhow, I did some digging, found that replication was never started, and initiated a replication through the following command:
Dfsradmin Membership Set /RGName:RG1 /RFName:DATA /MemName:DFSMEMBER /IsPrimary:True

Much to my surprise, it immediately started staging and 'replicating' data.  Server_b stated there were gobs of pre-existing data (expected, a ton of existing/expired robocopied crap there) which it moved to pre-existing, promptly overflowed, and got rid of (also expected, there's about 8TB I'm working with).  As time went on, I got constant event log hits on Server_A stating there was a file conflict, used algorithm to determine 'correct' one, as expected... sort of.  See, I expected the algorithm to determine that the primary server (Server_A) was in fact the holder of the primary copy, and just copy that file to the secondary server.  Much to my surprise when I came in this morning with a DFS drive half empty, and about 60% of my files were just *gone* from both Server_A and Server_B.  So, now I'm doing a restoral of the everything.

So I guess I'm looking for clarification on if it's even possible to take Server_A with pre-existing data, set up a replication group, with a second member, and have it just send the data over?  If Server_B is a mirror of Server_A, and you set as primary, is it supposed to delete everything from both systems?  That seems exceptionally counter-intuitive.

Thanks!

We added a remote location with a site-site VPN and set up a Windows Server 2012 box for file storage and DNS.  The firewall handles the VPN and DHCP.  The remote server is not a domain controller, so there is no domain trust.  The DNS zone is a sub of our internal.

A user with a Windows 8.1 tablet can not access our shared folders.  He can map to our DFS UNC, using his credentials defined on our domain, and he sees our list of DFS links. When he tries to open any folder, he receives the "network location cannot be reached" message.  I tried on the remote server and received the same results.  When I map to the shared folder on the file server, using the UNC in the DFS tree, the contents are accessible.

Everything else works well.

Thanks for assistance.

Hi

I have windows server 2008 with three physical HDD of 4 TB, 2TB and 2TB respectively.

I would like to know how to configure raid 5 at the startup.

Hello Everyone,

I have an issue that i need assistance on.  In Server 2012 R2 using Storage Spaces it seems to be unable to differentiate between 2 SSDs of the same model.  It sees them both but if i set one to "Offline" it thinks the other is offline as well but still lists it as online.  It also only shows one in the pool and not both.  If i place a different SSD in (830 series) it can differentiate and create a pool.  I have tried everything i can online about this but still no solution. Currently i have changed and am using then in a hardware RAID 1 off the LSI 2308 controller (performance is not as good).

Thanks

I've got a Windows Server 2003 server that has a number of Windows shares (shared folders) on it.  I have used ‘SETSPN –A HOST/<ALIAS> <SERVERNAME>’ and ‘SETSPN –A HOST/<ALIAS>.<FQDN> <SERVERNAME>’ plus a CNAME alias record in DNS to define an alias for accessing that server.

From a workstation on the network, if I UNC to \\SERVERNAME, it opens up a window with all the standard Windows shares as expected.  But if I UNC to \\ALIAS, it instead opens up a window with all the SharePoint shares and none of the Windows shares.

I have tried creating different CNAME alias records but no matter what alias I choose, they always open up the SharePoint shares instead of the Windows shares.

A number of scripts are built using the alias, so those scripts don't function now as they expect the Windows shares to be available at \\alias\share but instead all that's available are SharePoint shares which are useless to me.

Does anyone have any idea how this could have happened and how to resolve it?

I have Shared a Folder from File Server and it is been mounted as a Drive in all the client systems based on their permissions.

a particular Folder which i have created and mounted into a client system is making Issues.

a.The User has Modify Access, also i have tried to give him full rights.

b.actually this user is a member of Group Called (BSS).

c.I have given, Read access for the Group BSS and Modify access for this Particular User.

Issue:

The user can able to create, rename and delete files from the folder, also he can able to modify and save NOTEPAD test files.

But, When he create or access any MSOffice files, Excel... "ACCESS DENIED CONTACT ADMINISTRATOR" Prompts when he try to save the file.

Event Log:

The description for Event ID 300 from source Microsoft Office 16 Alerts cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

Hi

We are trying to implement files & folders NTFS & Shared permission in Server 2008 R2.

we have around 250GB Data and around 4 level of folders

e.g

common/Company1/departments/users

common/company2/department/users

common/company3/department/users

two way of implementation

1. Create three Groups in AD and denied co2 & co3 at Co1 and wise versa.

2. Shared Common folder and then remove co2 and co3 from co1 and same all.

method 2 is easy but have issue that after 3 level folders remove all permission and then no permissiom on folder.

can any body explain how much level we apply folders permission?

any help will highly appreciate.

I have a question about ADEVT extension file.

Now I am using WS 2008 R2 as file server and in C:\Users\Administrator\AppData\Local\Temp I found the adevt file which is 1G.

if possible I would like to delete it but not sure what it is,

I think I can delete because it is in the temp folder of the admin account,

would someone know what it is and if I can delete this

When I run the dfrsbacklog command using Server A as the sending member and Server B as the receiving member. Server A shows a single file in the backlog all the time. When I run the command using Server B as the sending member and Server A as the recieving member, the file doesn't show up. 

How do I remove this file from the dfrsbacklog command output on Server A when i know the file is replicating correctly?

Hi all.

On a Windows Server 2008 R2 machine I've turned on auditing on a few shares and am receiving the proper events (IDs 4663, 4656, and 4658) but unfortunately, it seems that I'm getting those alerts for files that haven't been deleted but have been edited. The one case that stands out is an Excel file (.xls). I've setup software to monitor those alerts and send an email but it's not helpful if I can't be certain if the file has been deleted or not. Anyone understand this problem and can offer some way to either change settings so the auditing doesn't report deletions for edited files or perhaps some way to distinguish between the two log entries for filtering? 4656 entries also appear to be the same I can post if anyone would like to see them.

The contents of the two are below for 4663. Private information has been changed or edited out. All other information is exactly the same for both.

This is what I get for the file that was not deleted but edited.

An attempt was made to access an object.

Hey,

We use folder redirection in our environment, redirecting to DFS shares.

For mobile devices (Tablets, Laptops etc.) we also use Offline Files.  I myself use a Surface Pro 4 tablet and I've had to logon/logoff 3 times today over the space of about 25 minutes for it to pick up all drive mappings, DFS shares.

The first time I logged in, I only had my own home directory mapped drive and when manually navigating the DFS Root, no folders existed (unless they had files I had made available offline).  So I logged off and on about 10 minutes later.  Had a couple more drive mappings this time and some DFS folders were available.  So logged off and on again just now and everything seems to have caught up.

Another user with the Surface Book has reported this issue to me too.  Here's the interesting thing.  This hasn't happened before for me because I normally leave my Pro 4 docked at work.  I took it home last night for the first time to play with it.  Came back in this morning and had these problems.  So it seems logging on to it while offline could be the cause.

Now the worrying thing:  the user with the Surface Book has reported Sync Center is deleting files because of this.

Where would I even begin to look to find the cause?

Thanks

All, We have Work Folders configured on a file server, hosting shares for about 60 users. I have a user experiencing an issue with Work Folders not syncing for over two months with the error:

"The Server is too busy to handle sync requests (0x80c8003e)"

Other users are not affected, and the server is by no means under resource or network strain. I cannot find any information related to this error, as Work Folders is not very common by any means. Any help or ideas are appreciated. Thank you. 

So recently my storage space came up with this reduced resiliency issue. However, as in many other cases around the net, all of the drives showed up OK, making it very hard to identify the failed drive.



As suggested in other posts, I unplugged the Toshiba and plugged it into my desktop. Then the WD that was plugged into my server became inaccessible.

Since I have solved the problem by myself, it is obvious that I am not asking for help here. However, I think this problem is serious, because if we are dealing with a corporate environment and multiple drives, they will not be able to find out the failing hard drive one by one like us casual users can. I really like Storage Spaces and ReFS, so I hope MS engineers can fix this problem.

Thanks.

P.S. When I was removing the failed drive from the pool, a "failed to remove drive" error showed up, although the drive was removed successfully. Thus I think the Storage Spaces system needs more polishing as well. Windows Server 2016 Technical Preview 5.

Hello!

I have a Dell PET620 running Windows Server 2012 R2 Standard. The only issue that has gone unresolved since installation is that the Search Index locks up. When it does this clients cannot use search options through the network to access necessary files. The only workaround I have found is to have someone manually stop and restart the Windows Search service.

I have rebuilt the Search Index multiple times in different locations and the outcome is the same. I also used the Registry to reset the SetupCompletedSuccessfully key which reset the Windows Search completely with no resolution.

Please help! Thanks so much :D

So I am confused as we have some great results with the servers, storage and networks but when file transactions go through the CAFS share path then huge performance hits.

Setup is:

2 X HP DL380 G9

2 X LSI 12 GB SAS HBA in each server

2 x 10 GBE Intel 540-TX2 in each server

1 x DataON DNS-2608 JBOD

12 x HGE 8TB SAS drives

4 x HGE 240GB SAS SSD

* Server 2012 R2

Business Case: 

We have the servers hardware / software fully patched and up to date.  We then created a File Server Cluster and all hardware passed checks with warnings on the network as we have not separated the Cluster and Data network.

MPIO is setup for the multiple SAS paths between the servers and JBOD and the dual 10 GBE nics are setup a LACP trunks.

Storage Spaces has been setup and we have created a Tiered space through the GUI with 44TB configured as 2-way Mirror using ReFS.

Then the File Server Role was setup from the Cluster Manager and a CAFS General Purpose role configured with CA shares setup.

The 10 GBE network cards are tuned and when we perform a standard UNC based file transfer between the servers we get 1-1.2GBps rates ie\\server1\c$\test to \\Server2\c$\test however when we perform the same data transfer using the CA, ie:\\cafs\test ,  transfer rates drop substantially to 150-300MBps

I have tried various configurations and every time we use the CAFS share path transfer rates drop to almost 1Gb network transfer rates,

We have for evaluation purposes even created brand new DC and FS servers so everything is fresh and a clean configuration.

Any suggestions are great.. I am even happy to hire someone that has a lot of experience with Storage Spaces and CAFS Volumes.

Thanks

DFS was configured and working fine on Server 2008 STD, but now it's no longer replicating.  Here are some of the errors I am seeing:

---------------------------------------------------------------------------------------
- Due to the following error, the DFS Replication reporting mechanism cannot access the WMI (Windows Management Instrumentation) namespace to retrieve certain reporting information. Error ID: 0x80041002.

I also have noticed that there is a disabled sysvol in the replication area which belongs to an decommissioned server.  Not sure if that would mess anything up or not since it is disabled (and not needed), but I can't get rid of it.
