How to enable traffic between VPN clients in Windows Server 2012 R2?

Hello,
I installed Remote Access role with VPN.
IPv4 Router is enabled: http://snag.gy/UAMY2.jpg
VPN clients should use static ip pool: http://snag.gy/REjkB.jpg
One VPN user is configured to have static ip: http://snag.gy/TWwq0.jpg
VPN server uses Windows Authentication and Windows Accounting.
With this setup, VPN clients can connect to server, get ip addresses and can see server via server's vpn ip. Server can connect to VPN clients too (Using client's vpn ips). But VPN clients can't communicate with each other.
For example, VPN server has ip 192.168.99.5
VPN Client 1 - 192.168.99.6
VPN Client 2 - 192.168.99.7
I am able to ping 192.168.99.5 from both clients, and able to ping 192.168.99.6 and 192.168.99.7 from server via remote desktop. But I am not able to ping 192.168.99.7 from client 1 and 192.168.99.6 from client 2.
If I trace route from 192.168.99.6 to 192.168.99.7 - I can see that packets goes to server (192.168.99.5) and next hop - request timeout.
What else should I configure to allow network traffic between VPN clients?

Hi,
To better analyze this issue, would you please post the routing tables on the two VPN clients? You can run "route print" at the command prompt to get the routing table.
Best regards,
Susie

Remote Desktop Services that require Native SQL Server Client in Windows Server 2012?

I have somehow gotten really confused on this.. Is the Remote Desktop Connection Broker the only Remote Desktop Service that requires the SQL Native Client to be installed in Windows Server 2012 (r2) ?

Hi,
If you plan on configuring RDCB in HA mode then the SQL native client is required. The other RDS role services do not require it.

App-V Client on Windows Server 2012

Hi all,
Could you please tell me if Microsoft support running the APP-V Client on a Windows Server 2012 image bundled as Windows 8 in a VDI solution?
Regards,
Mark

Bundled as Windows 8?? I'm assuming you mean RDSH?
If so, yes. You need to download and use the RDS version of the App-V Client.
If for some reason you actually mean a Windows 8 machine then also yes, you just use the Desktop version of the client. Both Windows 8 and Windows Server 2012 are supported in App-V, so you shouldn't have a problem.

How to Configuring case sensitivity for NFS on Windows Server 2012

Configure Case Sensitivity for File and Folder Names
http://technet.microsoft.com/en-us/library/cc725747.aspx
To configure case sensitivity for file and folder names using the command prompt
Open a command prompt.
To enable case sensitivity, type:
nfsadmin server [ComputerName] config casesensitivelookups=yes
But, "casesensitivelookups" is removed in Windows 2012 version.
Help Me~

Hi,
Sorry for the delayed response.
According to the following article, we still can use
nfsadmin to configure case sensitivity for Server for NFS in Windows Server 2012.
Nfsadmin
http://technet.microsoft.com/en-us/library/cc771599.aspx
Note:We
need to disable Windows kernel case-insensitivity in order for Server for NFS to support case-sensitive file names. We can disable Windows kernel case-insensitivity by clearing the following registry key to 0:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel
DWORD “obcaseinsensitive”
Hope it helps.

How do you remove virtual desktops from a Windows Server 2012 R2 Pooled VDI collection

All - I have created a Pool VDI Collection with 15 total virtual desktops in it. I need to reduce the number of virtual desktops in that collection to five. I have searched through the GUI, TechNet and done a number of Google searches but nothing helpful
comes back. Does anyone know how to do this?
I am guessing I cannot just delete them out of Hyper-V since the collection knows how many desktops it is supposed to have assigned to it.
Thanks in advance.
Will Smothers

Hi Will,
Thank you for posting in Windows Server Forum.
We can use PowerShell command “Remove-RDVirtualDesktopFromCollection“ to achieve your goal.
PS C:\> Remove-RDVirtualDesktopFromCollection -CollectionName "Virtual Desktop Pool" -VirtualDesktopName @("RDS-WKS-A27") -ConnectionBroker "rdcb.contoso.com"

How do you keep your VPN clients up to date?

Hi, how do you keep your Cisco VPN clients up to date? Our users connect to a Cisco 3015 Concentrator. It needs to be as automatic as possible.
Thanks

Check this link,
http://www.cisco.com/en/US/docs/security/vpn_client/cisco_vpn_client/vpn_cli
ent46/administration/guide/vcAch3.html
Example:
Steps to perform an automatic update for VPN client :
===================================================
1. Download update-4.8.00.0440-major-K9 file on your PC from the link below and unzip it.
http://www.cisco.com/cgi-bin/tablebuild.pl/vpnclient-3des
It will have the following files::
- binary_config.ini
- sig.dat
- vpnclient-win-is-8.00.0440-k9.exe
- vpnclient-win-msi-8.00.0440-k9.exe
2. Create a webserver with a folder and move all the above files to this folder on webserver.
3. Now on your vpn client create a new profile. This profile file will appear in the profiles folder of the vpn client. Copy this file to your desktop and zip it. Name the
zipped file as profiles.zip. Delete the profile from the client.
4. Make a copy of your binary_config.ini on your desktop. Rename it to new_update_config.ini. This is just to make sure its not saved as a txt file.
Open the above file and write the following on it:
[Autoupdate]
Required=1
5. Now move the new_update_config.ini and profiles.zip to the webserver. Once we browse to the webserver it should look like --
http://webserver/~razshah/vpn_profile_update462/
Index of /~razshah/vpn_profile_update462
Name Last modified Size Description
Parent Directory 09-Mar-2005 13:24 -

new_update_config.ini 11-Mar-2005 11:35 1k
profiles.zip 09-Mar-2005 13:26 1k
sig.dat 09-Mar-2005 13:26 2k
vpnclient-win-is-4.6..> 09-Mar-2005 13:26 7.6M
vpnclient-win-msi-4...> 09-Mar-2005 13:26 10.3M
6. The concentrator is configured as follows:
Client Type is Windows
URL http://webserver/~razshah/vpn_profile_update462
Revisions 4.6
7. On your PC go to the VPN Client > updates folder. Delete the update_config file if its already there. This folder should have only autoinstall (this file will be added if update works) autoupdate header files.
The update does take about 5 mins. To see the new file we have to close and reopen the client. Once connected make sure you are able to browse to the webserver and see all the files.
1- Auto update runs only on Windows 2000 and Windows XP, all other client types update manually. Windows NT users get notified and can get an update manually from the update server.
2- Remote users must have the VPN Client for Windows 4.6 or greater installed on their PCs to use the automatic update feature.

~JG

How to create a VPN client for Windows Phone 8.1?

We have our own VPN client for Windows and Android. I would like to create a VPN client for Windows phone 8.1. After referring these site I found that there are some third
party VPN plugins available for WP 8.1.
I checked OpenVPN but it is also not available for WP 8.1.
Is there any APIs available for creating a VPN client in WP 8.1 similar to
VpnService provided by Android SDK ?

The VPN APIs for WP8.1 are not open at this time.

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

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.
- ADEHART
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.

How to provide joins between oracle tables and sql server tables

Hi,
I have a requirement that i need to generate a report form two different data base. i.e Oracle and Sql Server.
how to provide joins between oracle tables and sql server tables ? Any help on this

Heterogeneous joins do not exactly scale and performance can be severely degraded by network speed and b/w availability. And there is nothing you can do in the application and database layers to address performance issue at the network level in this case - your code's performance is simply at the mercy of network performance. With a single glaring fact - network performance is continually degrading. All the time. Always. Until it is upgraded. When the performance degradation starts all over again.
If the tables are not small (few 1000 rows each) and row volumes static, I would not consider doing a heterogeneous join. Instead I would rather go for a materialised view on the Oracle side, use a proper table and index structure, and do a local database join.

Im using a mac system and adobe CS6 package. mainly works with Indesign, Illustrator and Photoshop.
But shortcuts doesn't works like Alt+I+I, Alt+I+S..... like that as on Windows computers.
Is there any way to enable "underline for shortcut letters" in mac for adobe products...?

Here in Photoshop on Windows OS you can see the letter for shortcut shown as underlined
In Menu bar
F for File
E for Edit
and I for Image
We can press alt+F to list file menu
and alt+E to list Edit menu
Is there any option like this to enable shortcuts for menu bar in "MAC OC"

How do I install user client access licence on Windows Server 2012

I have recently setup a Windows Server 2012 Std. I have not configured any roles yet. The server licence has been installed and activated successfully. How do I get my Windows Server CAL 2012 ( tracking ID is 15 digits) onto the server. I have google
but did not get the correct result. The closest I found was
http://technet.microsoft.com/en-us/library/cc540509(v=ws.10).aspx.
I am not too familiar with the Server 2012 display so I am not certain if I am missing something. If the CALs are not captured on the server, will this restrict user access to the 2012 server?
I thank you in advance for your assistance.

Hi,
I’m glad to hear that you have found the thread as reference. As DonPick mentioned, since these are Windows Server CALs, there is no activation nor input of any kind needed. You bought the
CALs, you have the paper, you are now licensed, there is no configuration step necessary. If there is anything else I can do for you, please do not hesitate to let me know. I will be very happy to help.

Windows 8.1 pro client on a Windows server 2012 R2 Essentials domain, how to change lock when idle?

Hi,
I need to find out how to do something?
I have Windows 8.1 pro running on my PC and its part of a domain which is Windows Server 2012 R2 Essentials, it all runs perfectly except for a little niggle where my Win 8.1 PC locks after its not used for a short time. What I want to find out is
how to change this so it no longer locks when idle? I know this is a security feature but as its just my home pc it can be very annoying to log in again after walking away from the PC for a few min's.
I've had a look through the default domain policy but there are so many settings that I can't find it, that's even if there is a setting there?
Anyway can anyone help?
Thanks

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).

Why does my Cisco router firewall block Windows Server 2012 traffic, but not Windows Server 2008 traffic?

Hello,
   I run a small business network with five physical servers: three Dell servers running Windows Server 2008 R2, one custom build running 2008, and another custom build running 2012 with Domain Controller Role (same hardware for both custom builds).
The Dell servers are all running the Hyper-V role and each has a number of 2008 VMs. I also have a 2012 VM with the Domain Controller Role on one of the Hyper-V servers and another VM with a completely base install of 2012.
   All servers are plugged into a Cisco SG300-52 switch which is uplinked to a Cisco 881 router which is connected to a cable TWC provided Ubee cable modem. I have no VLANs setup. I do have the Firewall on the router configured
to inspect most traffic.
   Here is my problem: I cannot connect to most of the internet on ANY 2012 server (and all exhibit the exact same behavior), but I have NO problems connecting to the internet from 2008 servers. Here is what I already know:
   1.) I can ping the outside world just fine so ICMP is passing to any external host.
   2.) Two of the 2012 servers are DCs running DNS services and they can connect to the internet just fine for DNS requests because they are doing a perfectly good job of providing DNS services to my network.
   3.) Here's where it gets really weird: I can browse in internet explorer to Bing.com and it works. I can also go to a couple other Microsoft websites (though they are very slow). If I click on any link in Bing, however, it doesn't
work and gives me a page not available error. If I connect to a non-MS website like Google or my company website, I get page not available.
    4.) I have tried to telnet to port 80 at Bing and it works. I have tried to telnet to port 80 at google.com and it won't connect. The 2008 servers have no issue telneting to either bing or google on port 80 and none of my client
PCs on the network do either.
    5.) Windows Update will not connect and neither will any other update service such as AVG (I have AVG Antivirus installed WITHOUT firewall on two of the three servers. The base 2012 VM has no software installed and no roles...I built it
just to see if it could connect after a fresh install and it still cannot.)
    6.) The network connection does not indicate limited connectivity (probably because ICMP appears to be passing successfully)
     7.) If I connect the server directly to the modem it has full internet access.
     8.) All internal LAN connectivity is perfectly fine and runs at full speed.
     9.) I have scoured the internet trying to find other examples of this particular kind of connectivity issue on 2012 and I have found two TechNet articles that are similar, but they both had the same resolution: changing the router
worked, but no one knows why. (I would have included the links, but apparently I cannot do that yet)
My question is this: What is different about Windows Server 2012 networking that would render it unable to communicate through a router that Windows Server 2008 has no problems with? I ask because, unlike in these two articles where they were
running personal networking equipment they could easily upgrade, I'm running a Cisco 881 with what should be virtually limitless configuration options and I have no desire to replace it. I have to assume the issue is somehow related to the firewall configuration,
which I could fix easily, but I don't know what to change. If anyone knows what changed in 2012 and why I would be able to browse to bing and other MS sites but no where else, please pass them along. Thanks.
