Hello Windows Universe! Michael with The Windows Club who is averse, who will amaze you with knowledge and is ready to launch an attack on malware thugs.
In this article we're going to look at the SMBport and why it's important. We will also talk about port 445 and port 139. There's a lot to do, so we'll link an article in the description that goes even further.
SMB stands for ServiceMessage Blocks. In modern programming language, it is also known as the Internet File Assistant. The system operates as an application layer network protocol primarily used to provide shared access to files, printers, serial ports, and other types of communication between nodes on a network.
In most cases, the use of SMB involves computers running Microsoft Windows, where it was known as the Microsoft Windows Network prior to the advent of Active Directory. It can be run on the session network in a number of ways. For example, SMB can run directly over TCP-IP without the need for a network bios, and this uses port445.
On other systems you can find services and applications that use port 139. All of this has to do with the basic input-output system of the network bios or the network. It is a software protocol that enables application PCs and desktops on a local network to communicate with network hardware and transfer data over the network.
Software applications that run in a Net-BIOS network find and identify each other via their Net-BIOS names. When two applications start a net bios session, one computer or the client sends a command that is invoked over TCP port 139 to the other computer, the server. The Net-BIOS in your wide area network or Internet is an enormous security risk.
All important information such as your domain, your workgroup, system name and your account information can be called up via the network bios. This makes an effective firewall essential, as a firewall will block this port first as a security measure. It is also used for file and printer sharing and once exposed, it opens your hard drive for a hacker to attack.
Once a hacker is on an active 139 port, a hacker can take simple steps to obtain vital information about you and your computer. Then port 445 is deeply embedded in Windows and it is hard to close safely, but it can be closed. It depends on the DHCP or the dynamic host configuration protocol.
Malicious hackers admit that port 445 is vulnerable and has a lot of insecurities. One example is the silent appearance of Netbios worms. These worms slowly and methodically scan the Internet for instances of port 445, transfer themselves to the new victim's computer, and then duplicate their scans.
It's a terrifying thought that their massive bot armies with tens of thousands of machines compromised by Net BIOS worms inhabit the Internet. For this reason, many ISPs find it necessary to block this port on behalf of their users. Have you now encountered security problems on ports 139 and 445?

If you have ever used network drives in Windows, you have probably encountered this problem where Windows reports that some or all of your network drives could not be mapped, but when you use the Open the Explorer window and click on such an offline network drive, then it works fine and changes its status from offline to online.
Now this is not a new problem introduced with Windows 10, Windows 8, or even Windows 7. If you look for this problem online then you can find topics from users who had this problem even in Windows XP which is just mind blowing since you think such problem would be pretty important for Microsoft to get it fixed asap Drives then you know how annoying this problem can be, especially if it only occurs occasionally, as you will probably only find that some of your network drives are offline after you've already opened a project file like Adobe Premiere that has some assets in it is not available or if AutoCAD cannot access your project folder because it is on such an offline network drive or if your MediaCenter tells you that it cannot access any of the sources because of this problem. So, like many others, I've tried registry tweaksgroup policy changes that are supposed to make Windows wait for the network to be ready before connecting the network drives, I've disabled Fast Boot, I've changed the order in which Windows services start I've tried a lot of scripts as well as used the windows sync feature for offline files to make sure the network drives are online and a lot more.
But even though some of these measures worked or only worked for a short time on some PCs, I couldn't find a solution that would fix the cause of this problem on all PCs and simply prevent it, so in today's article I want to show you 2 workarounds that unfortunately don't fix the cause of this problem, but at least make sure that all network drives are online when you start your PC so that you don't have to manually click them in Windows Explorer to make them available to your applications. Now let's say you've already mapped all network drives and want a very simple solution that doesn't require you to configure anything. A solution that needs to be as simple as starting a script like this one.
So how did my script remap my network drives even though I didn't say anything about my network drives. First it waits until the network is ready, otherwise it cannot access the network shares. Once the network is ready, the script waits 5 seconds to avoid the next command failing on slower PCs.
Then the script uses the 'net use' command to get a list of all offline network drives. In this case, 6 offline drives were found, R, S, U, V, Y and Z. The X drive is no longer offline because I clicked on this drive before.
Then it uses the Explorer windows to access each of these offline network drives the same way as if you clicked each of these drives in Windows Explorer. Then the script waits again for a few seconds to give the system some time to access the network drives before it closes the open Explorer windows. And that was it! Now all network drives are shown as online and can be accessed by all of your applications.
So if you are suffering from the problem of network drives showing up as offline but you can still access them by simply clicking them in Windows Explorer, then you can use my script to have it do the job for you. And unlike other scripts, mine doesn't require any configuration at all as it detects the offline network drives by itself. So if you want to use this script then there is a link to this website in the description of this article where you can download the latest version.
Once you've downloaded the script, unzip the zip file, rename the folder, then save it somewhere where you won't accidentally save it, delete it, then create a shortcut and change its properties, to start the script minimized so that the command prompt window does not appear in the center of your monitor when you boot your PC. In order to start this script automatically when you start your PC, all you have to do is move this shortcut to the start folder of your own user account or the one that is used for all users. So to access the startup folder for your current user, go to start, type run, type shell: startup, and then move or copy the shortcut into that folder.
So when you start your PC now, Windows will run this script waiting for the network to be ready before then accessing and reconnecting the offline network drives so your applications can then use the drives and you don't have to customize within the script as it does everything by itself. The other script I want to tell you about, for which you can also find a download link in the description of this article, works a little differently; it also checks that the network is ready before it does anything, but you need the drive letter and enter the path of each network share you want to map in Windows, with the permanent NO flag saying that Windows will forget this network drive when you shut down or restart your PC if you need to provide a user and password to access the share To access, you can either paste this information into the script which is not secure, or you can go to 'Manage Windows Credentials' and add that information here, add all your network drives in this script, create a shortcut, change it Properties to start the script minimized, and then move this shortcut to your user's home folder, etc. that of all users so that Windows only connects your network drives once the network is ready.
So again I know that my scripts are only workarounds as they don't fix any causes for network drives to appear offline even though they are online. But at least you no longer have to manually open open exploring and click on each offline drive to let Windows know that they are actually online. And that's all for today.
Hope you found this article interesting and if you have tried any of my scripts please leave a comment below as I am very interested to hear if they worked for you.
