This is not optimal for fast internet connections with intermittent bursts of data. The following should work for server, however it does not work in Windows 8. It is sometimes useful to view and set the Maximum Transmission Unit MTU value for a specific network adapter manually. To view a list of active network interfaces, their names and their respective MTU values in Windows 8, open PowerShell or command prompt as administrator and run the following command:.
For example, if the name of your network card is "Wi-Fi" and you'd like to set its MTU to , you'd have to type:. Below is a list of what we've confirmed to work. To edit the Windows Registry, click the Windows button, and type: regedit in the search dialog you may have to right-click regedit and choose to run as administrator to have the proper write permissions.
It is always a good idea to create a restore point and backup the registry before making changes. TTL does not directly affect speed, and can be safely left alone in many cases.
A number that's too small risks packets being discarded before reaching their destination. A number that's too large over will cause delay in when lost IP packets are discarded.
It is important to note that this increases their priority compared to the hundreds of other running processes, while keeping their order. See our Host Resolution Priority Tweak article for more details. The registry location under Windows 8, 8. However, under heavy network load it may be necessary to adjust these two registry settings to increase port availability and decrease the time to wait before reclaiming unused ports. If the default limits are exceeded under heavier loads, the following error is observed " address in use: connect exception ".
Recommended: 30 decimal, denoting 30 seconds - time to wait before reclaiming ports, in seconds. Default time before reclaiming ports, if value is at 0xffffffff or not present in the registry is or seconds, depending on your OS. Just reducing the delay is often sufficient without changing MaxUserPort, as it allows for reusing ports more efficiently.
Note this only has effect in the presence of running QoS applications that request priority traffic, like Windows Update, for example. Recommended: 0 , possible values between 0 and - indicates the percentage value of reserved bandwidth for QoS applications. Set to 0 to disable. In order to define DiffServ DSCP values, according to Microsoft the machine needs to have joined a domain, and interfaces have to see the domain controller.
To overcome this limitation, so that you can tag DSCP values even for adapters that do not have access to a domain, use the following hidden registry key:. Notes: gpedit. This registry key may also be needed in systems with multiple network adapters present.
When this happens, you can usually see the following error in the Event Viewer System log: Event ID: "The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations. To avoid those errors, you need to change the way Windows allocates memory for network services and file sharing.
The below settings optimize the machine as a file server so it would allocate resources accordingly. There are two related registry settings:. In addition to explorer.
For more information, see our Web Browser Tweaks article. Note: Increasing this setting much over 10 can cause incomplete page loading and other issues with some pages. The idea behind such throttling is that processing of network packets can be a resource-intensive task, and it may need to be throttled to give prioritized CPU access to multimedia programs. In some cases, such as Gigabit networks and some online games, for example, it is beneficial to turn off such throttling all together for achieving maximum throughput.
It is only recommended to change this setting in saturated Gigabit LAN environments, where you do not want to give priority to multimedia playback. Reportedly, disabling throttling by using ffffffff can also help reduce ping spikes in some online games. This setting, in combination with the above "NetworkThrottlingIndex" can help some games and video streaming. In some server operating systems Windows Server , the SystemResponsiveness may be set to , instead of 20 by default.
This is by design, giving higher priority to background services over multimedia. See also: MSDN ms Nagle's algorithm is designed to allow several small packets to be combined together into a single, larger packet for more efficient transmissions. Keep in mind that disabling Nagle's algorithm may also have some negative effect on file transfers. Nagle's algorithm is enabled in Windows by default.
To implement this tweak and disable Nagle's algorithm, modify the following registry keys. Find the correct one with your IP address listed. For gaming performance, recommended is 1 disable. For pure throughput and data streaming, you can experiment with small values over 2.
Wifi performance may see a slight improvement with disabled TcpAckFrequency as well. Note you can also set this to 1 to reduce the nagle effect from the default of ms without disabling it.
Note that only version 4 of the prorgam supports Windows 8 and newer and works with PowerShell cmdlets. There program is available in our downloads section. More detailed information about all available options is provided in the TCP Optimizer documentation , answers to frequently asked questions are available in the Optimizer FAQ , and personalized help is available through our forums.

In our example, we have Windows 10 Pro build 20H2 installed. Actually, if the installation media is not Retail but Volume, it is not required to execute slmgr.
If a server cannot find KMS host, you can specify it using slmgr. So, in my case with standalone server this was enough: slmgr. If you are activating Windows 7 or Windows 8 desktops the proper way to do this is to activate via your own KMS Server. However, I have seen servers need to be manually activated via KMS more often than not. But yes I agree with your last statement, seems kind of strange the way they activate with KMS. Windows Home Server was announced on January 7, , at the Consumer Electronics Show by Bill Gates and is intended to be a solution for homes with multiple connected PCs to offer file sharing, automated backups, and remote access.
Intended use was for building firewall, VPN caching servers and similar appliances. Availability of the original version ended May 28, Availability of R2 ended March 5, End of extended support was July 14, all variants except Storage Server [9] , and End of Licence was May 28, R2 and original. All variants continued to receive Critical security updates until the end of extended support: [37]. While many features of the bit variant of Windows XP were brought over into Windows XP Professional x64 Edition, other limitations imposed by constraints such as only supporting bit drivers, and support for bit programs being dropped led to incompatibilities with the bit Windows XP editions available.
Among the improvements are many of the same updates that were provided to Windows XP users with Service Pack 2. Features that are added with Service Pack 1 include:. A full list of updates is available in the Microsoft Knowledge Base. Service Pack 2 for Windows Server was released on March 13, This was followed by build , known as Beta 2 Refresh. The final build is Microsoft has described Service Pack 2 as a "standard" service pack release containing previously released security updates, hotfixes, and reliability and performance improvements.
Service Pack 2 also adds Windows Server Scalable Networking Pack SNP , [48] which allows hardware acceleration for processing network packets, thereby enabling faster throughput.
Windows Server R2 is an updated release of Windows Server , which contains a copy of Windows Server SP1 on one CD and a host of optionally installed new features on another disc, similar to Microsoft Plus! New features of Windows Server R2 include: [51]. On July 13, , Windows Server 's mainstream support expired and the extended support phase began.
During the extended support phase, Microsoft continued to provide security updates; however, free technical support, warranty claims, and design changes are no longer being offered. Although Windows Server is unsupported, Microsoft released an emergency security patch in May for the OS as well as other unsupported versions of Windows including Windows Vista and Windows 7 RTM without a service pack , to address a vulnerability that was being leveraged by the WannaCry ransomware attack.
Anonymous users from managed to compile the Windows Server source code, as well as a Twitter user who posted videos of the process on YouTube proving that the code was genuine, [57] but was removed from the platform on copyright grounds by Microsoft. The leak was incomplete as it was missing the Winlogon source code and some other components. Microsoft issued a statement stating that it was investigating the leaks.

Microsoft's policy has no bearing on how third-party software vendors such as Oracle administer CPU licensing for its server applications. Main article: Windows Small Business Server. Main article: Windows Home Server. Main article: Windows Embedded. DFSR spends most of its time in initial sync—even when administrators preseed files on the peer servers—examining metadata, staging files, and exchanging version vectors.
This can make setup, disaster recovery, and hardware replacement very slow. The existing initial sync portion of DFSR is now instantaneous if there are no differences. If there are differences, DFSR only has to catch up the real delta of changes as part of a shortened initial sync process. Cloning provides three levels of file validation during the export and import processing.
These ensure that if you are allowing users to alter data on the upstream server while cloning is occurring, files are later reconciled on the downstream. What does this mean in real terms? Our 64TB tests with 70 million files only take a couple days! I like exclamation points! The Export-DfsrClone provides sample robocopy command-line at export time. You are free to preseed data any way you see fit backup and restore, robocopy, removable storage, snapshot, etc.
With Windows Server and prior versions, file server administrators do not have modern object-oriented Windows PowerShell cmdlets to create, configure and manage DFS Replication. While many of the existing command line tools provide the ability to administer a DFS Replication server and a single replication group, building advanced scripting solutions for multiple servers often involves complex output file parsing and looping. Can develop and deploy complex automation workflows for all stages of the DFSR life cycle, including provisioning, configuring, reporting and troubleshooting.
Allows creation of new graphical or script-based wrappers around Windows PowerShell to replace use of the legacy DfsMgmt snap-in, without the need for complex API manipulation. Some slick things happening here, such as creating the RG, RF, and members all in a single step, only having to run one command to create connections in both directions, and even polling AD on all computers at once! I have a lot more to talk about here — things like wildcarding, collections, mass edits, multiple file hashing; this is just a taste.
