Enabling network discovery on Windows Server 2012 R2

Good afternoon.
As per the title, I have set-up a new server at work. The server is running no problem but none of the other computers connected to the network can 'see' the new server. I've gone into the control panel and tried to turn on the network discovery, but it just
defaults back to 'off'.
I did so a search on here first before troubling anyone and I did find this answer :
Thanks for the post.
I did some research and found this issue may occur if the dependency services are disabled. Please make sure the following services are enabled and running.
- SSDP Discovery
- UPnP Device Host
Disabling Network Discovery/Network Resources"
That may well be the answer, but unfortunately that means absolutely nothing to me.
Is someone able to help me try and switch this on, but by offering an explanation an 'idiot' would understand.
Thanks in advance.

Hi,
This issue occurs for one of the following reasons:
•The dependency services for Network Discovery are not running.
•The Windows firewall or other firewalls do not allow Network Discovery.
To resolve the issue, follow these steps:
1.Make sure that the following dependency services are started:
DNS Client
Function Discovery Resource Publication
SSDP Discovery
UPnP Device Host
2.Configure the Windows firewall to allow Network Discovery. To do this, follow these steps:
Open Control Panel, click System and Security, and then click Windows Firewall.
In the left pane, click Allow an app or feature through Windows Firewall if you are running Windows Server 2012. Or, click Allow a program or feature through Windows Firewall if you are running Windows Server 2008 or Windows Server 2008 R2.
Click Change settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Select Network discovery, and then click OK.
3.Configure other firewalls in the network to allow Network Discovery.
4.Turn on Network Discovery in Network and Sharing Center

HP LaserJet Pro 200: Scanning to Network Folder on windows server 2012 - can't find folder

I have searched everywhere and tried every suggested solution with no luck. Hence this post.
I have an HP Laserjet Pro 200 on our small company network (domain). We use windows server 2012 as our domain controller and as our file and print server.
There is a shared folder on the windows server that is shared read/write with everyone on the domain.
I can access the shared folder from any computer on our network.
However, when trying to setup the scan to network folder capability, the HP web interface always comes back that it can't find the network folder.
I have tested that it will work on our network if I want to scan to a shared folder on any of the other computers on our network (other than the main server).
So it appears to be some sort of security / firewall issue with our server, perhaps ?
Does anyone have any suggestions on how to troubleshoot this issue? Is there any technical documentation on how a server environment needs to be changed to allow this to work ? (BTW, this used to work, about a week ago and nothing changed except for installing the latest HP laserjet drivers on the windows server.
Thanks for any suggestions.

0x8056530b error enabling disk deduplication on Windows Server 2012 R2 Volume - any ideas why or how to fix?

I'm getting the following error when trying to enable disk de-duplication on a volume on my Windows 2012 R2 file server. The error is:
"There was an error updating Data Deduplication on volume: MSFT_DedupVolume.Volume='\\?\Volume{8dfc4322-9997-11e3-93f5-005056a84b9b}\' - HRESULT 0x8056530b, The specified volume type is not supported. Deduplication is supported on fixed, write-enabled
NTFS data volumes and CSV backed by NTFS data volumes."
The volume in question is a 1TB VMFS volume mounted to the virtual machine that is the Windows file server. I could find no info anywhere that references this error as it relates to a standard mounted volume or VMware or VMFS.
Any ideas on what could be the problem or how to fix it? I could find nothing in the log files other than an entry which is basically a repeat of the error above.
Any help would be greatly appreciated.

P.S. This is a volume that was previously mounted on an older Windows 2003 server. Not sure if that may make a difference.

have you compared this issue to the ones that are successful and compared what is different?
Have you made sure of the following:
Servers
See the following list for server requirements for deduplication:
• Server hardware should meet the minimum requirements for running Windows Server 2012. The deduplication feature was designed to support minimal configurations such as a single processor system with 4 GB of RAM and one SATA hard disk drive.
• If you plan to support deduplication on multiple volumes on the same server, you need to plan an appropriately size for the system to ensure that it can process the data. The general rule is that the server needs 1 CPU-core and 350 MB of free memory to run a deduplication job on a single volume, and that job can process about 100 GB per hour or around 2 TB per day. Deduplication scales with additional CPU core processors and available memory to enable parallel processing of multiple volumes.
For example: If you have a server with 16 CPU core processors and 16 GB of memory, deduplication uses 25% of the system memory in the default Background Processing mode, and in this case, that would be 4 GB. If you divide by 350 MB, you can calculate that the server could process about 11 volumes at a time. If you add 8 GB of memory, the system could process 17 volumes at a time. If you set an optimization job to run in Throughput mode, the system will use up to 50% of the system’s memory for the optimization job.
• Data Deduplication supports up to 90 volumes at a time; however, deduplication can simultaneously process one volume per physical CPU core processor plus one. Hyper-threading does not impact this because only physical core processors can be used to process a volume. A system with 16 CPU core processors and 90 volumes will process 17 volumes at a time until all 90 volumes are done, if there is sufficient memory.
• Virtual server instances should follow the same guidance as physical hardware regarding server resources.
Volumes
Volumes that are candidates for deduplication must conform to the following requirements:
• Must not be a system or boot volume. Deduplication is not supported on operating system volumes.
• Can be partitioned as a master boot record (MBR) or a GUID Partition Table (GPT), and must be formatted using the NTFS file system.
• Can reside on shared storage, such as storage that uses a Fibre Channel or an SAS array, or when an iSCSI SAN and Windows Failover Clustering is fully supported.
• Do not rely on Cluster Shared Volumes (CSVs). You can access data if a deduplication-enabled volume is converted to a CSV, but you cannot continue to process files for deduplication.
• Do not rely on the Microsoft Resilient File System (ReFS).
• Can’t be larger than 64 TB in size.
• Must be exposed to the operating system as non-removable drives. Remotely-mapped drives are not supported.
Note
Files with extended attributes, encrypted files, files smaller than 32 KB, and reparse point files are not processed by deduplication.

Unable to add network printers from Windows Server 2012 R2 to client running Windows 7 Pro x64

New Windows Server 2012 R2 Standard in the environment. Added print services to it and added five HP printers to it and shared them. Also deployed the printers via group policy.
Clients are running Windows 7 Pro x64. The group policy fails to install the printers (error 0x00000002). We get the same error when trying to manually add the printer from the client side.
From Event Viewer: Group Policy was unable to add per computer connection <<printer share>>. Error code 0x2. This can occur if the name of the printer connection is incorrect, or if the print spooler cannot contact the print server.
Any ideas on troubleshooting this?
Thanks.
-John

John,
You might try playing with the HP universal driver, that might help you. Try installing a new shared printer on the server using the universal print driver, then try and connect to it to see if it is any better.
Check these GPO settings to ensure local machines can install the drivers.
1. Configure the following two Group Policy settings:
Computer Configuration\Policies\Administrative Templates\System\Driver Installation\Allow non-administrators to install drivers for these devices setup classesEnabled
2. Device class GUID of printers: {4d36e979-e325-11ce-bfc1-08002be10318}
Computer Configuration/Policies/Administrative Templates/Printers/Point and Print RestrictionsEnabled
Security Prompts: When Installing Drivers for a new connection = Do not show warning or elevation prompt

Windows Server 2012 enable memory Turbo boost

Hello guys.
I have a Sony Vaio VPC-F113FX notebook with Quad Core Intel i7 processor with 8GB of RAM.
It is installed a Windows Server 2012 Standard.
I bought an SD card of 64 GB and intended to use the Turbo Boost feature in memory, only this option is not displayed in the properties of the operating system memory card. Can you help me configure or enable this feature in Windows Server 2012.
Thanks
Obrigado por contactar o fórum Microsoft Technet!

Hi Hezequias,
Thanks for posting.The Turbo Boost feature is just provide by Intel can cab be obly used on the Intel i5 and Intel i7.
As you mentioned that you used a 64GB SD card and intended to use the Turbo Boost feature, so I guess you might talked about the Ready Boost.
Ready Boost is a feature provide by Microsoft, Ready Boost is a disk caching software component which allows any compatible mass storage device to be used as a hard-drive memory cache for the purpose of increasing random read access
speed to the hard drive. Potentially compatible ReadyBoost devices include USB flash drives, flash memory,solid-state drivers(SSDs), and SD cards. There is a limitation of 32 GB per ReadyBoost device.
However the Ready Boot feature was just supported by the Microsoft Clients(such as windows 7) but not the server edition.
So the feature can't be used on windows server 2012 standard operation system.
Hope it helps.
If you have any concerns, feel free to post back.
Best Regards,
Elaine

Hi,
If you access files stored on Windows Server 2012 R2 from other non-Windows client computers, you need to use NFS protocol.
Using the NFS protocol, you can transfer files between computers running Windows and other non-Windows operating systems, such as Linux or UNIX.
In Windows Server 2012, NFS includes the components, Server for NFS and Client for NFS. Server for NFS enables a computer running Windows Server 2012 to act as a NFS file server for other non-Windows client computers. Client for NFS enables a Windows-based
computer that is running Windows Server 2012 to access files that are stored on a non-Windows NFS server.
For more detailed information, please refer to the articles below:

Windows Server 2012 Hyper-V network latencies

Hi All,
I have an issue with our Windows Server 2012 Hyper-V hosts that I can't seem to figure out. Situation:
2 x Dell PowerEdge R815 servers with AMD opteron 6376 16 core CPU's and 128 GB RAM running Windows Server 2012 with Hyper-V.
2 virtual machines running on the same physical host and connected to the same virtual switch show high TCP connection latencies. One virtual machines runs a SQL Server 2012 database instance and a Dynamics AX 2012 R2 instance. The other machine a
SharePoint 2013 instance and the AX client. We see latencies of 20ms and higher on most of the TCP connections that are made from the sharepoint machine to the sql server machine.
At first I thought it might have something to do with the physical NIC's. It turned out that VMQ wasn't correctly supported by the firmware of the Broadcom BCM5709c cards. By default this setting is enabled. Turning off the VMQ setting somewhat improved
the situation but the latencies are still at 8ms and higher.
What I don't understand is what influence enabling/disabling VMQ should have on network performance. As I understand it now virtual machines connected to the same virtual switch bypass the physical altogether. Another point is that VMQ should actually improve
performance, not decrease it.
Another question I have is about the various tcp offloading settings on the physical NIC's. After installing the new firmware and drivers from Dell most of these settings are set to disabled. The documents I have been able to find talk about Windows Server
2008, any thought how these settings relate to Windows Server 2012 and whether they should be enabled?
Thanks in advance for your time and thoughts
Kind regards,
Dennes Schuitema

Hi Denes,
Please try to update your BroadCom NIC driver version ,the newest version should be 7.8.51
For details please refer to following link :

Windows Server 2012 - Remote Apps - Mapped Network Drive Error

Hi Technet

I have been able to do this pn 2008 R2 like 100 times with no problems, hope someone can help plz

Aurimas... try the method I tried and let me know if it works for you...
To publish an Application that is available only on a Mapped Drive.
E.g. Sage Pro Application needs to run as T:\Pro73\sbtw.exe
We have to be aware that it may give an error sometimes because it tries accessing the IconPath variable and that needs to be on a local path "C:" or "D:"
We were successful in publishing the application by runnig the command twice in Powershell.
The first time it gave an error and the second time it published it successfully and also made it available on the RD Web Access:
PS C:\Users\administrator.LAFE> New-RDRemoteApp -CollectionName QuickSessionCollection -
DisplayName "SagePro200" -FilePath T:\PRO73\sbtw.exe -IconPath "C:\Windows\RemotePackages
\CPubFarms\QuickSessionCollection\CPubRemoteApps\sbtw.ico"-UserGroups "lafe\citrix users"
Please note that it will show TWO SagePro200 RemoteApp Program names and the Aliases will be sbtw and sbtw(1), but only the later one will be visible online and workable.
You can always go back and 'unpublish' the extra RemoteAPP if you want to keep your interface clean.
Hello,
I was able to publish remote app using this method, but I had to specify icon path in UNC as I was performing the publishing operation from
RDCB server and my guess is that it was looking for icon in "C:\windows\..\program.ico" on the
RemoteApp server where the icon did not exist. After specifying -iconpath as UNC
\\RDCB\C$\windows\...\program.ico command was successful.

Enable Lan Routing Windows Server 2012

Hi!
I'm trying to setup the RRAS in a Windows server 2012 to route between my two networks. I have a windows server 2012 with two nics and the RRAS installed. I installed "Lan Routing" custom option.
My configuration is:
Server nic1 - 192.168.1.254 255.255.255.0 (no dfgateway)
Server nic2 - 192.168.103.54 255.255.255.0 (no dfgateway)
Clients subnet1 - 192.168.1.x 255.255.255.0 192.168.1.254
Clients subnet2- 192.168.103.x 255.255.255.0 192.168.103.54
The problem is that from a client of subnet1 i can ping 192.168.1.254 and 192.168.103.54 but i can't ping clients of subnet2, and backwards the same problem.
Thanks.

Your client machines need to know how to find the route to the other subnet.
1) So on a client on subnet 1, open a Command Prompt and type:
route add -p 192.168.103.0 mask 255.255.255.0 192.168.1.254
This adds a permanent route which tells the client to go to 192.168.1.254 to find network 192.168.103.0
2) On the clients on subnet2 you would type:
route add -p 192.168.1.0 mask 255.255.255.0 192.168.103.54
Make sure the clients have the appropriate server NIC address as their default gateway and DNS.
For example, for clients on subnet1:
IP: 192.168.1.x
Gateway: 192.168.1.254
DNS: 192.168.1.254
That is misleading at best. The original post is a straight forward example of subnet to subnet routing. No additional routes are required because the default routing is quite adequate. If you look at the addresses of the static routes you provide
you will see that they are the same as the default addresses already set (so they are redundant).
Ping is not a reliable test of connectivity any more. Built-in firewalls will block it by default. You will need to temporarily disable the firewalls of the clients to test with ping (unless you enable ICMP echo in both directions on all clients).

Network Connection error when Trying to Install Windows Server 2012 R2 Essentials

Thank you to anyone who can help me out here. I have a brand new machine with known working wifi and wired ethernet adapters (works under Windows 8.1) I am attempting to install Windows Server 2012 Essentials R2. During the install process, the system connects
to the internet to download updates to help along the install. No problem here. Further down the road after restarting several times and now during the "Configuring Windows Server Essentials" step of the install, I am told "There is no network
connection. Please fix the connection issue and try again."
When troubleshooting the connection, I am told that the wifi adapter drivers may not be installed. I have a wireless card in the machine and have also tried disabling the wifi adapter and have been connected successfully via the ethernet port this whole
time.
Help, I'm stuck and have been to this point in the install 4-5 times already.
Thank you.

Is this a laptop? Can you remove the wifi? Disable it in BIOS?
Does the wifi have an IP and internet when it throws the error?
BTW, when the wizard ask about updates say no. Takes way too long and does not help anything
Change the binding order and put the wired on top.
The Steps?
Just open your Network and Sharing Center. (Change adapter settings)
Press an ALTkey on your keyboard to show the menu bar.
Click on the Advancedmenu
choose Advanced Settings option
Adjust your binding order for your NICs to ensure your wired ones are at the TOP

Windows Server 2012 R2 - ADFS/Windows Network Load Balancing Converging Issue

Hello,
My name is Brandon. We have started upgrading our servers to Windows Server 2012 R2. We have some powerful servers for running ESXI 5.5 as the OS with the Guest Operating Systems as Windows Server 2012 R2. As far of our migrations/upgrades we have configured
ADFS 2012 R2 into a Server Farm with Windows Network Load Balancing to add redundancy in the event a server goes down.
I have been having issues with a Node with the Cluster getting stuck in the Status of Converging. The only way I have been able to get it back up is to restart the virtual server completely and it is temporary. When I first configure the Cluster the two
virtual servers get added to the Node with no problems and fully converge. However, after some time a node will end up in Converging and this takes Authentication for ADFS down as the nodes can not be contacted over Port 443.

Hi,
According to your description, my understanding is that：2 ESXI 5.5 physical devices (192.168.0.5 and 192.168.0.6), each of them has a virtual WS 2012 R2(192.168.0.10 and 192.168.0.20). Cluster the 2 virtual servers successfully, but they corrupt with event
ID 21, and a restart of virtual device will resolve this problem temporarily.
Event ID 21 means that NLB failed to converge due to inconsistencies in the port rules between this host and cluster host. This will occur if the number of port rules or the type of port rules are different between hosts.
Ensure that all NLB hosts have identical port rules. Detailed steps you may reference:

Windows Server 2012 R2 - Windows Network Load Balancing Converging Issue

Hello,
My name is Brandon. We have started upgrading our servers to Windows Server 2012 R2. We have some powerful servers for running ESXI 5.5 as the OS with the Guest Operating Systems as Windows Server 2012 R2. As far of our migrations/upgrades we have configured
ADFS 2012 R2 into a Server Farm with Windows Network Load Balancing to add redundancy in the event a server goes down.
I have been having issues with a Node with the Cluster getting stuck in the Status of Converging. The only way I have been able to get it back up is to restart the virtual server completely and it is temporary. When I first configure the Cluster the two
virtual servers get added to the Node with no problems and fully converge. However, after some time a node will end up in Converging and this takes Authentication for ADFS down as the nodes can not be contacted over Port 443.

I have tried using 1 & 2 Virtual NICs on the machines and still receive this error even if only 1 VNIC is assigned to the virtual machine. Could someone assist me with why I am having this issue? Has anyone had experience with a similar configuration
and how were you able to make it work?
Below is my configuration.
Static ARP Entry for Cluster IP Address has been added to our Layer 3 switch.

Thank you for your response. It took me a while to figure it out, but the whole issue was related to the type of Virtual Network Adapter I was selecting.
I changed the network adapter from E1000 to VMXNET 3 and have not had a single error in the event logs or Windows NLB.
I read somewhere that VMXNET 3 is preferred for Windows Server 2012 R2.

"Just a help for everyone with this problem :
After 10 days of research for our virtual datacenter behind a vcloud as iias , i found a solution .
I only run windows 2012 server .
Install vmware tools , remove e1000 network card after a vm stop, add a card same vswitch etc BUT with a vmxnet3 TYPE . DONT USE DEFAULT CARD
Start and enjoy this solution . E1000 and E1000e are just unstable in windows8 / windows 2012 , the network card reset randomly with or without heavy IO. No log in windows , and as a vcloud user i don"t have esxi logs (damn i don't like cloud) and provider
don"t know why ..."

Unable to install Network Adapter Driver for Windows Server 2012

Hi,
We have purchased a new computer for our office. And on that machine, we want to install Windows Server 2012 Standard with GUI.
Windows Server got installed on that machine. But we are unable to install drivers for our LAN card Intel® 82579V Gigabit Network Connection.
Please help us to get it working.
Thanks,
Ronak Shah

It is not working as the system is having Intel® 82579V Gigabit Network Card
I guess, it's not supported on windows server 2012

NOTE: The following devices do not have driver or software support for Windows Server

- Intel® 82566MC Gigabit Network Connection
- Intel® 82566MM Gigabit Network Connection
- Intel® 82567LF Gigabit Network Connection

- Intel® 82577LC Gigabit Network Connection
