Executing a .exe or appref-ms file throug file screen of File Server Resource Manager on Windows Server 2008 R2

Hi All,

          Scenario: An excel file containing some records is uploaded through FTP on the server and is required to be read and saved into database by an .Net windows application, and to generate subsequent alerts including some database insertions.

Propose Solution:

                               I'm trying to build a desktop .Net application in VS 2010 that would have all the business logic/functional requirements. I have created a file screen in File Server Resource Manager . The .exe or or appref-ms file would then will be executed through the file screen that looks for an excel file upload.

Issue:

I have installed the application on the target server. I have put the path of appref-ms file in command tab of the file screen (Which looks like C:\Users\Administrator\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Microsoft\FTP_Contracts.appref-ms).  When i upload the excel file, got an error that details as  'Createprocess 0x800700c1 is not a valid win 32 application'.

Please tell me if there is any thing wrong in this approach or there is any other way to achieve this. What could be the reason the above error.

I would really appreciate if somebody could reply. Thanks in advance.

Best way to keep a folder in synch between multiple datacenters

I'm looking for a way to synchronize a folder from one server to another.
I want one server to be a master server and all the other servers should receive the file(changes) from the master server quickly after they have been edited or added/deleted.

I've been looking in to DFS, but I believe this requires setting up a domain.
I've tried this in the past but the domain also changed all my user account logins, which is something I want to avoid on a server which has already been setup.

Another thing is that the servers are located in different locations of the world, so the traffic go's over WAN.
All servers use Windows Server 2012 R2.

What would be a good solution/implementation for this scenario?

Slow loading of shared DLL files

December 7, 2012, 12:57 am

We have built a system with a Windows Server Standard 2012 as the host and two Windows 7 as the clients connected on a gigabit TCP/IP network.

On the host, a 64-bit MFC-based executable (app) and some small-size dependent DLL files are located and shared to Everyone with the full control right. The app can be run either on the host or on the client.

When the app is run the first time on any of the clients, it starts up quickly/normally  - Taking ~1 second - with all the DLL files being loaded quickly.

However, the next run of the app, either on the host or on the other client, takes 3~4 min to start up. Process Explorer showed that each DLL file loading took 30~40 seconds.

It was also found that during the slow start up, if the first client is shut down, both the ongoing and the rest of the DLL loading finished quickly giving a sudden start up of the app.

BTW, the slow start up has never been seen on an old system with Server 2003 (host) and XP (clients).

Anyone with similar experience?
What would be the possible causes?
How to fix it?

Thanks a lot in advance.

Post Server Upgrade "files cannot be accessed by the system"

November 21, 2013, 8:25 am

Here is the back brief:

I came in to two (2) NAS servers being used as a primary and backup user shares. Both are HP X1600's that were running MS Storage Server 2008. As far as I could tell there was a standalone DFS setup which was not set up to replicate to the backup server. However daily robocopies were pulled from the production to the backup box.

To meet certain security policies I have upgraded the OS of both servers to 2008 R2 Enterprise.

Since then we had permissions issues with the folders, so I did the following to initially fix the "file cannot be accessed by the system"

Took ownership of all files as the local administrators group.

Using icacls.exe i pushed a backup of the permissions back to the folders,

and then net share to reshare the folders with correct permissions. This cleared up a majority of the issues.

However we are still having intermittent access issues, there doesnt seem to be any rhym or reason but files are still unaccessable to myself (elevated user) and our share users ( are in AD security groups)

I have yet to install the MS iSCI software target or enable Multipath I/O. I turned DFS on but am not replicating and have not created a namespace. I read something about having an old DFS link still present might cause this but i could not find one anywhere in AD.

If the files are restored from backup, then they work as expected, however as this is 6TB+ of data to catch all files I would have to restore all and that is not plausible in our current setup.

To reiderate,

OS upgrade MS Storage Server 2008 -> Server 2008 R2 Enterprise.

DFS enabled but not replicating, no name space created.

All File securities are set as well as share permisions.

Administrators and share group users have issues accessing files within shares but not entire folders just random files within.

MS iSCSI Software Target and Multipath I/O not installed or configured.

Restore from backup fixes issue but would like to find the root cause.

Searching Remote Indexed 2008 R2 Server FROM a Server 2008 R2 Server not working

Using windows explorer FROM a Server 2008 R2 Server to a UNC on a Remote Indexed 2008 R2 Server is not working.  The search results are displaying results from the file contents (i.e. searching 'instructions' in the contents yields no results).  Any ideas?

More info & background:

  • 2008 R2 server trying be searched has file services role installed + windows search service feature installed
  • UNC is shared properly & included in the index
  • searching from the file server itself yields results inside the file contents (so I know it's working)
  • from a windows 7 pc I can add this share to my document library (so I also know that the remote index is working)
  • from a windows 7 pc with OR withOUT the share in the document library the search results DO yield the file content results
  • from another 2008 R2 server used as a citrix or remote desktop services server:  I do NOT get search results for the contents NOR can I add the share to the document library

What am I missing, any suggestions?

DFS Waiting for initial replication

March 1, 2011, 4:23 pm

Good Morning,

We recently had an issue with DFS where older files from our DR servers were overwriting newer files in our production server.

Too immediately resolve this issue, we severed the DFS links in our topology.

Now I am at the point where I am trying to rebuild two replicated folders within a DFS group. Here are the steps I have taken:

1) found out which DC's each file server were talking to.

2) Deleted the replicated folder ("Finance") from DFS Management

3) ran a DFSRDIAG POLLAD for AD to pickup the change

4) on each DC ran a repadmin syncall to replicate the changes

5) confirmed that all the File servers recieved the changes

6) Stopped DFS replication service on all File servers

7) Deleted the DFSRPrivate Directory from all the "Finance" folders on the file servers.

8) restart DFS replication service on all file servers

9) created a new replicated folder called Finance that points to the original replicated folder shares

I am now waiting for initial replication to kick off. the changes above were made approximately 14 hours ago. Since then, the status in the DFS health report remains at "waiting for initial replication". I have done some investigation and have found that it is currently going through and generating hashes for all the files.

It originally reported a backlog of 180000 transactions to send and recieve. After 14 hours, this number has dropped to 170000 transactions to send and recieve.

My question is:

Is it possible to speed up the process of cataloging and comparing the files for replication?

 

Over the past 14 hours, there have been no spikes in CPU, Memory or IO. As well, only 65 MB has been transferred between the file servers. Based on my calculations, it will take 4 days for DFS to go through and synchronize the file shares. Is there any way to dedicate more resources to DFS to speed this up? Or am I doing something wrong in my process to resync/pre-seed these files.

Any assistance would be greatly appreciated.

Kind Regards,

Jacob Estrin

WS2012R2 Datacenter Hyper-V hosts with WS2012R2 Fileservers (SMB & Infiniband) Failed to modify device "virtual hard disk" on all VMs

Hello everyone.

We have a setup with 4x hosts running WS2012R2 Datacenter Hyper-V towards 2x Fileservers WS2012R2 connected to a shared JBOD. All of the servers communicate over infiniband. 

We run the Hyper-V over SMB with RDMA on a CSV volume that has deduplication enabled.

We were so happy that Window server 2012 R2 was released recently so we upgraded right away and finnaly things were stable , no longer any spamming errors of hard disks in use or bsoding hosts! All have been great since the release but something happened this weekend without any of us doing any changes.

All of a sudden my System Center 2012 VMS running SQL clusters with the new "Shared VHDX" feature failed. I started to investigate the problem and it seems that we cannot "change or edit" any virtual hard disks on our entire VM share. If i try to use advance features and change to shared vhdx it fails, it does not matter if its a new vm i create or a old one.

I need some help with this, I feel clueless to why it happened or how to fix it? 

Thank you,

Marcus

Access Based Enumeration hiding accessible files?

November 22, 2013, 3:53 am
$

Hi,

I've just migrated our main 2003 file server to 2008 R2 and enabled access based enumeration.

This has hidden everything in the share from my users. Disabling ABE allows users to see all the folders and get into ones that were previously hidden.

Each folder in the root of the share is configured with 'Special Permissions' and they are for 'Domain Users' to have 'Traverse folder / execute file' and 'List folder / read data' permissions to  'This folder only'.

It seems that this level of access is not enough for ABE to class the folder as accessible, even though users can browse through them when ABE is disabled.

What level of permissions do I need to assign to folders for ABE to class them as accessible?

Thanks,

James.

We are running a Dell NX3200 NAS (Windows Storage Server 2012).  It has been in operation for a few weeks, but we started having major issues yesterday.  Three times in the past 24 hours,but we cannot remote into it via RDC, logmein, etc.  Also, all users lose access to their file shares.  However, we can ping the server.  After a hard reset, services are restored for a while.  I don't see anything in the Event Viewer that would indicate what is causing this.  Any ideas where to troubleshoot next?

Drive mapping issue

November 22, 2013, 7:37 am

Hello,

My company runs a server with Windows Server 2008 R2 SP1. Starting about a week ago, we are having trouble with mapped drives accessing from the Internet. Within our wireless LAN, we can reach the server using \\ShareName\Shared folder, no problem. From offsite (connected to another internet access, like my smart phone hotspot or offsite WiFi) we used to be able to access our server with a DNS address like 'ServerName.Company.coop' and map the drives for file access. (We've checked with our ISP and the DNS is pointing correctly.) Now, we cannot map the drive from offsite. In the dialog, we choose a drive letter, enter the server name as 'https://ServerName.Company.Coop' and hit finish. We leave reconnect at logon checked, and have tried asking for new credentials, and also not asking. When we hit finish, it thinks for a bit, then usually asks for a username and password. We enter it, and it returns:

"Windows cannot access https://SERVERNAME - Check the spelling of the name. Otherwise there might be a problem with your network." and in the details, "Error code: 0x80070043, The network name cannot be found"

We are able to access the server using Remote Desktop, and can cut and paste files to and from the server that way, but it is very clumsy and some of my people don't understand how to do it. I am not really familiar with how mapping works and am not sure where to start looking to track this down.

Any suggestions you can offer will be much appreciated, thank you!

I am currently migrating from 2003 standard file server to 2008 R2 standard. I am using Windows file server migration toolkit 1.2 to move the shares. The first time I was attempting to move everything over I received alot of errors stating that there are file paths to long after the "validating settings" step. I am resolving those and I ran it again to get a up to date list of the file paths that exceed 260 characters. I got the list but also I got a few "System Error: 64, The specified network name is no longer available". Now I can explore to these locations and access the files/folders. I'm not sure why this is happening now and not before, but any information will be greatly appreciated.

Server 2012R2 - Thin provisioned out of space when 14TB still available

November 11, 2013, 9:43 am

Hi,

Suspect this is a configuration error but I can't see where.

Original system install was Server 2012 Data Center with six 3TB disks (showing as 2.73TB each). Storage Pool was created with ReFS out of the six disks. 5 disks were set as AUTOMATIC and 1 as HOT SPARE, the storage pool is configured as PARITY layout with THIN provisioning and a capacity of 40.0TB.

System was upgraded a month ago to a new install of Server 2012R2 Data Center on new hardware (Supermicro X9DRi-LN4+ with dual 8 core CPUs and 128GB or RAM). System boot drive is a 128GB SSD. Drives were installed in the new server and Storage Pool was recognized fully accessible.

System was running low on disk space, so 4 new 3TB drives identical to the ones already installed, were added to the storage pool and usage was configured as AUTOMATIC for each.

The problem is that the Storage Pool claims to be out of space. We cannot copy files to it "Out of space" message is given.

In the storage pools window the capacity reported is 27.3TB, free space 12.9TB, percent allocated bar is roughly 50%. When looking at properties for the pool it reports 14.4TB is used. So the math adds up.

When we right click on the disks in the Physical Disks window the following information is provided:

Disk 0 - 405GB used
Disk 1 - 405GB used
Disk 2 -   2.73TB used
Disk 3 -   2.73TB used
Disk 4 - 256MB used
Disk 5 -   2.73TB used
Disk 6 -   2.73TB used
Disk 7 -   2.73TB used
Disk 9 - 256MB used
Disk10 - 256MB used

In the Virtual Disks window layout reported is PARITY, provisioning THIN, capacity 40.0TB and Allocated 11.5TB. Version of the Storage Pool was upgraded to Windows Server 2012 R2.

The actual amount of data on the drives is just about 11.5TB.

This appears to be an allocation problem, but I've looked everywhere to find a way to allocate the available disk space in the pool but I cannot find a place to do so. Everything I've read to date says "allocation is automatic" and that there are no specific settings to allocate space. Server was rebooted several times.

Any suggestions would be greatly appreciated.

I am unable to get instance of a dynamic disk, using Storage management API Classes.

I used the sample code for Storage Management Application and modified such that it takes Disk Number as argument for fetching the disk instance.
I get the following error:
Failed to Get an Instance of Disk. Error Code is '6'.

The function returns with Invalid Handle error.
Can someone suggest on how can we fetch the instance of a Dynamic disk using Storage Management API Classes / Functions?
