NLB - WIndows Server - Application server redirection according to IP range

November 23, 2016, 11:35 am

A long time ago I did not work with Windows Server NLB.
Is it possible via NLB to route incoming requests to different application servers based on the user's IP?
I would like to force requests in Europe to go to my application server in Europe. And requests from Asia went to Asia.
That is, the balancing is not by the load, but by the locality of the user.

Hi all,

I'm trying to run the process manager SMPD on a remote computer in LAN environment. Computers are 64-bit, running Windows 7 pro, Ethernet connected via wired router, and have same account's user name and password. The following WMIC has been written to command prompt: WMIC /node:SERVER /user:"Said El Noshokaty" /password:"soudy73" process call create “cmd.exe /c smpd.exe -d”. I received "Invalid verb switch" error message. It does not tell what verb or what switch. I need a solution which considers SMPD running within a Fortran 64-bit program using RUNQQ command. 

Need help.

Hi, guys

I notice that, I could not use the 'SELECT * FROM Win32_PerfRawData_Tcpip_TCP' to query the wmi object 'Win32_PerfRawData_Tcpip_TCP' in the windows server 2003 (5.2.3790), and I can use the 'Win32_PerfRawData_Tcpip_TCPv4'for query.

But I want to known from which version we couldn't use the 'Win32_PerfRawData_Tcpip_TCP' any more?  5.2 or other version?

Thank you for any help!

I have found that temporary capture will causes network to stop working with loss of data. Lifting the capture size will help but only in relation with traffic.

I apologize if this may seem out of forum scope, I am not sure where else to ask. 

My question is of a two fold nature, the first being:

Can a URL with an embedded share to face book "button" be analyzed for traffic, as in, the amount of shares to face book? 

(Online website offer this service free, this I know)

The second and most important being:

The date inwhich this webpage or URL was shared to face book?

Thank you

Internet fine, network not

I have excellent internet access. (well, perhaps somewhat of an overstatement, since I have satellite internet service). I have a wired PC, a wired TV and a wired "smart" audio receiver, two wired satellite TV receivers, as well as one laptop, two tablets, and a smartphone connected by wifi (cell service sucks at my house). All of these have decent internet access through by dish Modem and a DLink AC3200 router. None of these devices can see each other, nor can they see the NAS connected to the network by Ethernet. I am now running evaluation build 17074, but even before I loaded the insider build I was having the same problem. Until this morning most, but not all of my devices were able to see the NAS, now even that is gone. I've run several networking commands, including a reset, and multiple restarts with no effect. update: after removing the network adapter on the PC and rebooting, I can see the satellite TV receivers, but not the NAS, and none of the wifi devices. On may tablet I can see nothing on the network. Yes, it is private and network discovery is on, on all devices. 

Any ideas would be appreciated.

Hi Guys, 

I'm trying to capture packets on a specific destination port (port 25) using powershell commands, and would need some help. I have attempted two ways, but hasn't worked.

Method 1:

param([UInt16[]]$ports=25)
New-NetEventSession -Name "Capture" -CaptureMode RealtimeLocal -LocalFilePath "C:\Users\5.etl"
Add-NetEventWFPCaptureProvider -SessionName "Capture" -TCPPorts $ports
Start-NetEventSession -Name "Capture"

Method 1 Result (Error): 

Start-NetEventSession : A general error occurred that is not covered by a more specific error code.
At line:4 char:1
+ Start-NetEventSession -Name "Capture"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (MSFT_NetEventSe...EFDF64462B1D}"):root/StandardCimv2/MSFT_NetEventSession) [St 
   art-NetEventSession], CimException
    + FullyQualifiedErrorId : MI RESULT 1,Start-NetEventSession

Method 2:

param([UInt16[]]$ports=25)
New-NetEventSession -Name "Capture" -CaptureMode RealtimeLocal -LocalFilePath "C:\Users\5.etl"
Add-NetEventPacketCaptureProvider -SessionName "Capture" -IpProtocols $ports
Start-NetEventSession -Name "Capture"

Method 2 Result:

Captures all traffic and doesnt limit it to dest.port 25, and i'm not sure of the arguments that could be used for -IpProtocols

Appreciate any help on this.

thanks.

Hey Guys,

Dont really know if this is the right forum, but figured I would ask anyways.

My issue comes down to not seeing the same network option in Windows 10 as compared to Windows 8. I was wondering if it was put somewhere different.

Win8 Steps:

  1. Select "Change Adapter Settings"
  2. (seeing my 2 NICs Wifi and Ethernet) Press the ALT key
  3. Select Advance > Advance Settings
  4. Under "Adapters and Bridges", you will see Connections that shows the order of the NICs

Windows 10 doesn't show this and was curious why?

Hi,

I am trying to do a PowerShell script that gets a report of the physical network interfaces, one of the properties that I need to retrieve is the interface type (according IANA https://www.iana.org/assignments/ianaiftype-mib/ianaiftype-mib), for Windows 8/2012 and higher there is no problem, that information is at MSFT_NetAdapter.InterfaceType or by Get-NetAdapter cmdlet, but the WMI object and the netadapter module are not available at 2008 R2. Do you know any other WMI Object where I can find the interface type (IANA) on Windows 2008 R2?

Thanks,

Cesar F.
