How to check SMB version on Windows 10

SMB or Server Message Block Protocols are used to connect your computer to an external server. Windows 10 ships with support of these protocols but they are disabled in the OOBE. Currently, Windows 10 supports SMBv1, SMBv2, and SMBv3 as well. Different servers depending upon their configuration require a different version of SMB to get connected to a computer. But in case you are using Windows 8.1 or Windows 7, you can check if you have it enabled too. That’s what we are going to do today.

How to check SMB version on Windows 10/8/7
First of all, if you have Windows 7, you should not be disabling SMB v2. This is due to the following reasons:


  • Request compounding – allows for sending multiple SMB 2 requests as a single network request
  • Larger reads and writes – better use of faster networks
  • Caching of folder and file properties – clients keep local copies of folders and files
  • Durable handles – allow for connection to transparently reconnect to the server if there is a temporary disconnection
  • Improved message signing – HMAC SHA-256 replaces MD5 as the hashing algorithm
  • Improved scalability for file sharing – the number of users, shares, and open files per server greatly increased
  • Support for symbolic links
  • Client oplock leasing model – limits the data transferred between the client and server, improving performance on high-latency networks and increasing SMB server scalability
  • Large MTU support – for full use of 10-gigabyte (GB) Ethernet
  • Improved energy efficiency – clients that have open files to a server can sleep.
  • Even if you are on Windows 8.1 or Windows 10, you should not be disabling SMB v3 or SMB v2 because, in addition to the above problems, you might face the following issues too which come with disabling SMB v3:

  • Transparent Failover – clients reconnect without interruption to cluster nodes during maintenance or failover
  • Scale Out – concurrent access to shared data on all file cluster nodes
  • Multichannel – aggregation of network bandwidth and fault tolerance if multiple paths are available between client and server
  • SMB Direct – adds RDMA networking support for very high performance, with low latency and low CPU utilization
  • Encryption – Provides end-to-end encryption and protects from eavesdropping on untrustworthy networks
  • Directory Leasing – Improves application response times in branch offices through caching
  • Performance Optimizations – optimizations for small random read/write I/O.

Enabling the Computer Browser service for Windows Server

  You can configure a computer so that it does not send announcements to browsers on the domain. If you do so, you hide the computer from the Browser list, which can help reduce network traffic. Editing the Registry 1. Open the registry editor and go to Microsoft Registry 1 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters 2.From the Edit menu, choose Add Value and type: Hidden Note: This value is case sensitive and must begin with a capital H. 3.In the Data Type field, choose REG_DWORD and choose OK. 4.In the Data field, type 1 to enable hiding and choose OK. 5.Restart your computer. Using the NET CONFIG SRV command This setting can also be changed using the following command: net config server /hidden:yes|no To hide the computer from the Browser List, type net config server /hidden:yes at the command prompt, and then press ENTER. To unhide the computer from the Browser list, type net config server /hidden:no at the command Find more :  lanmanserver windows

The Advantages of Authentication

There are numerous advantages of authentication systems which are used to identify the user of a home, ATM or a security clearance computer system. The main purpose of these systems is to validate the user's right to access the system and information, and protect against identity theft and fraud. While there are still drawbacks with some systems, as the business world and the electronic marketplace become more complex, the advantages of authentication are ever more obvious. Password Based Authentication The use of a password and username is the most common form of authentication used and is generally considered the cheapest and most convenient method. This requires the user to provide and remember a key containing a specified amount of alpha and numeric characters in relation to a username or e-mail address which must be correct at each login. Passwords saved on a network can be encrypted to prevent theft by employee or programs designed by hackers. Device Based Authenticatio

Server Work Queues of networking

  This is something you should only measure on your Terminal Server(s). You should monitor the "current commands" in the Redirector object. If the value is higher than 20 during sustained periods of time then you could have a bottleneck. Server Work Queues The Server Work Queues object should be monitored on the File server. You should monitor the "Available WorkItems" counter. Sustained values smaller than ten mean that the File server is running out of work items. When it does, performance really starts to plummet. Make sure this doesn't happen by upping the MinFreeworkItems value. Server In this object there's a counter called "Work Item Shortages". This value represents the number of times no work items were available or couldn't be allocated to service a file request. Obviously if you see any other value than zero, you need to start worrying. Upping the InitWorkItems or MaxWorkItems could help out here. Again, there's so much more you
