The nbstat command takes a significant amount of time to run, so this slows down this script considerably. However in my opinion, the value add of getting a machine name is worth the wait. Note that the nbstat command is not completely effective or guaranteed to resolve a name. However this is unreliable and not guaranteed to work so you will need to judge for yourself its effectiveness for the network that you are taking a look at.
I found the following article at TechRepublic article about the nbstat command to be very interesting. Have a look if you are interested in finding out more about its inner workings.
Also, in case you are not getting the results from nbstat that you are expecting, try using a different keyword in the FIND command. Please feel free to write me a note in the comments below. I have written a follow-up article to this article that addresses the issue of non-pingable machines on a network.
This article expands on the examples I have described in this post and explains how to increase the accuracy of the machine detection routine. I specialize in Web application development with a focus on building secure systems, integrating applications, and designing robust database structures. View all posts by Justin Cooney. I like your first batch file. I was to get my batch to display on the active ip addresses and their names.
Is that possible? Thanks for this simple script. As Chris mentioned by default nbstat is not installed on HomeEditions of Windows. But I tweaked the script enough to find the active machines on my network. Nice, any way to process the resulting. I would like to make a batch utility that; 1-Ping several network address to see that they are active. Server2 23ms server3 10ms server4 40ms Connection slow!

You won't be able to create new 'CloudServiceConfiguration' pools or add new nodes to existing pools after February 29, The Virtual Machine Configuration specifies that the pool is composed of Azure virtual machines.
These VMs may be created from either Linux or Windows images. The Batch node agent is a program that runs on each node in the pool and provides the command-and-control interface between the node and the Batch service. There are different implementations of the node agent, known as SKUs, for different operating systems.
When you create a pool based on the Virtual Machine Configuration, you must specify not only the size of the nodes and the source of the images used to create them, but also the virtual machine image reference and the Batch node agent SKU to be installed on the nodes. For more information about specifying these pool properties, see Provision Linux compute nodes in Azure Batch pools. You can optionally attach one or more empty data disks to pool VMs created from Marketplace images, or include data disks in custom images used to create the VMs.
When including data disks, you need to mount and format the disks from within a VM to use them. Cloud Services Configuration pools are deprecated. Please use Virtual Machine Configuration pools instead. Cloud Services provides only Windows compute nodes. When you create a pool that contains Cloud Services nodes, you specify the node size and its OS Family which determines which versions of.
NET are installed with the OS. Cloud Services is deployed to Azure more quickly than virtual machines running Windows. If you want pools of Windows compute nodes, you may find that Cloud Services provide a performance benefit in terms of deployment time. The primary use case for selecting a specific OS version is to ensure application compatibility, which allows backward compatibility testing to be performed before allowing the version to be updated. Any running tasks will be interrupted and requeued.
To learn how to create a pool with custom images, see Use the Azure Compute Gallery to create a custom pool. Alternatively, you can create a custom pool of virtual machines using a managed image resource.
Currently, you must create the pool using an image that supports Docker containers. The pool settings must include a container configuration that copies container images to the VMs when the pool is created. Tasks that run on the pool can then reference the container images and container run options. For more information, see Run Docker container applications on Azure Batch.
When you create a pool, you can specify which types of nodes you want and the target number for each. The two types of nodes are:. Spot nodes may be preempted when Azure has insufficient surplus capacity. If a node is preempted while running tasks, the tasks are requeued and run again once a compute node becomes available again.
Spot nodes are a good option for workloads where the job completion time is flexible and the work is distributed across many nodes. Before you decide to use Spot nodes for your scenario, make sure that any work lost due to preemption will be minimal and easy to recreate.
You can have both Spot and dedicated compute nodes in the same pool. Each type of node has its own target setting, for which you can specify the desired number of nodes.
The number of compute nodes is referred to as a target because, in some situations, your pool might not reach the desired number of nodes. For example, a pool might not achieve the target if it reaches the core quota for your Batch account first.
Or, the pool might not achieve the target if you have applied an automatic scaling formula to the pool that limits the maximum number of nodes. For pricing information for both Spot and dedicated nodes, see Batch Pricing. When you create an Azure Batch pool, you can choose from among almost all the VM families and sizes available in Azure.
Note that node sizes can only be chosen at the time a pool is created. In other words, once a pool is created, its node size cannot be changed. For dynamic workloads, you can apply an automatic scaling policy to a pool. The Batch service will periodically evaluate your formula and dynamically adjusts the number of nodes within the pool according to the current workload and resource usage of your compute scenario.
This allows you to lower the overall cost of running your application by using only the resources you need, and releasing those you don't need. You enable automatic scaling by writing an automatic scaling formula and associating that formula with a pool.
The Batch service uses the formula to determine the target number of nodes in the pool for the next scaling interval an interval that you can configure. You can specify the automatic scaling settings for a pool when you create it, or enable scaling on a pool later.
You can also update the scaling settings on a scaling-enabled pool. As an example, perhaps a job requires that you submit a large number of tasks to be executed. You can assign a scaling formula to the pool that adjusts the number of nodes in the pool based on the current number of queued tasks and the completion rate of the tasks in the job. The Batch service periodically evaluates the formula and resizes the pool, based on workload and your other formula settings.
The service adds nodes as needed when there are a large number of queued tasks, and removes nodes when there are no queued or running tasks.
When automatic scaling decreases the number of compute nodes in a pool, you must consider how to handle tasks that are running at the time of the decrease operation. To accommodate this, Batch provides a node deallocation option that you can include in your formulas. For example, you can specify that running tasks are stopped immediately and then requeued for execution on another node, or allowed to finish before the node is removed from the pool.
Note that setting the node deallocation option as taskcompletion or retaineddata will prevent pool resize operations until all tasks have completed, or all task retention periods have expired, respectively. For more information about automatically scaling an application, see Automatically scale compute nodes in an Azure Batch pool.
To maximize compute resource utilization, set the target number of nodes to zero at the end of a job, but allow running tasks to finish. The max tasks per node configuration option determines the maximum number of tasks that can be run in parallel on each compute node within the pool. The default configuration specifies that one task at a time runs on a node, but there are scenarios where it is beneficial to have two or more tasks executed on a node simultaneously.
See the example scenario in the concurrent node tasks article to see how you can benefit from multiple tasks per node. Although it will take quite a bit longer to complete, you can also resolve the IP Addresses to HOST names by simply adding -a to the ping command. This is from Here. I know this is a late response, but a neat way of doing this is to ping the broadcast address which populates your local arp cache. This can then be shown by running arp -a which will list all the addresses in you local arp table.
This post asks the same question, but for linux - you may find it helpful. Send a ping to each IP on a subnet. It is available for the windows platform on the nmap. All you are wanting to do is to see if computers are connected to the network and to gather their IP addresses. I have found this tool very helpful when trying to see what IPs are being used that are not located inside of my DHCP. Some things seem appeared to have changed in batch scripts on Windows 8, and the solution above by DGG now causes the Command Prompt to crash.
