IT Ninjas: Mastering Network Troubleshooting in Windows
Vložit
- čas přidán 24. 06. 2020
- Practical steps for troubleshooting Windows 11 and Windows 10 network connectivity for local and remote users. We'll also look at effective troubleshooting for wired and wireless users. From PowerShell to portable apps, we'll look at tools that can help IT professionals do their work.
I'll share my experience with handheld tools for network troubleshooting in a large enterprise. From using built-in tools in Windows to uninstalling NICs and how to perform a network reset. Understand the impact of non-functioning browsers, malware, and expired anti-virus products. Finally, online speed test sites can accurately test the network device for download/upload and latency tests.

GOOD STUFF AWS LAUNCING PAD. THANKS.
Thanks for watching!
OUTSTANDING!!!
Please check out the rest of our video library!
I use the useful "test-netconnection -port" PS command to check if a port is open on a server or pc, but for all other troubleshootings I continue to use the good old command lines like ping, netstat, tracert or nslookup because in case of network issue we are in a hurry and the powerhsell commands are longer to type and for some of them complicated to remember :)
Did you investigate why your "show wlan report" did not work? (error 2)
And please use "Windows + i" shortcut to acces the W10 settings instead of going in the start menu LOL :):):)
Keep up the useful work Lowell :)
Love the comments!!!! Be safe in that great country of yours!
First like even before watching the video. :)
You should get money from CZcams as the 1st!
Very good. Be careful and ask before plugging in an unauthorized device (thumb drive), or it could get you in trouble!
Maybe bringing another laptop would be a good idea for referencing
Most endpoint anti-virus automatically run against flash drives plugged in, but yes if it is an unknown drive be very cautious but if it is drive I use as an IT pro for daily work, no problem.

Welcome
putting in....they are only visible on the mini sof
You do not need to check the cable to know if it’s connected!!
Windows will give you the adapter status. If it say connected, it is!
If it says not connected, then check.
Good point, but most folks would not understand those icons in the system tray, you and I would so hopefully to ask them to look to see if the cable is in the back of the computer, they might be able to do...... prior to having to go up to the ninth floor to plug in the network cable. Love the comments!!!
Mr.V after trying these steps, is there a chance that the problem still persist ?
Lejn Yovn, yes I did not cover the many scenarios found in complex enterprise environments, incorrect VLANs, missing DHCP servers, switch uplink failures/misconfigurations, I have seen one pin on a patch cable bad giving strange results, failed NIC, corrupt NIC driver, IDS (security appliance) shutting down the client and more. I will add these to the notes. Thanks for the question, it was a good one and for watching!
@@TechsavvyProductions Thank you so much for your reply Mr.V. I don't have a great teacher like you in india.
9:40 As a Level 1 Help Desk? Isn't this the job of on-site support? I may be viewing things with the lens of my past work experiences though, someone please correct me. Are there some L1 positions that require this deep level of expertise?
Great point, some larger companies Level 1 never leave a phone desk but smaller companies are more active both on phone and desktop support.
@@TechsavvyProductions
Thank you! :)
What happened to your I/O shield?
Sharp eye! I believe the original I/O shield came twisted and damaged and after some effort to fix, the pressure on the motherboard attempting to get screws in, I decided to leave out. I normally do not like modifying air flow and removing RFI/EMI protection.
God bless 🙏🙏🙏🙏🙏🙏🙏
The same to you!
That's how you should put people to work.
Thanks for watching!
LinkRunner is a fabulous tool, I have a 2000 that's saved me all kinds of time, got it before the prices climbed into the stratosphere.. it now goes for over $2500.. the only thing wrong with them is that people try to steal them.. I don't let anyone touch mine.. you can also update the software, also record your name and address in them, it's a part of the system you'll have to find.. that has stopped people who tried to take mine.. it's amazing how much gall some people have...
Thanks for taking the time to comment!
At about 11 minutes into this video there's a picture of a Fluke CIQ-10 Cable Qualfier with what looks like a price of $25.00.. these things also great but that $25 price is real WRONG... they're now up to over $2000.. between a LinkRunner and a CIQ-10 you can run every test you need to check connectivity.. the LinkRunner will "talk" to a switch, get it's make, model, name and port number and the CIQ-10 will tell what the cable is rated at..
That was a mistake, nothing Fluke makes is cheap : ) They are great tools.
Maybe just use the word NIC with the R
thanks for watching!
Hello, can you share the text of the script? Regards
In the video description of most of my videos are links for download video notes and PPT for each presentation
Uninstalling a device will NOT delete the driver.
Older versions did allow a check box to uninstall the driver, newer versions of Windows 10 removed it. Too many people uninstalled the driver and were stranded.
Given to Any practical training class
Thank you for watching!
A regular help desk person CANNOT deal with most network issues.
Much less in network closets.
We all know a few of those, but looking at life half full, there are a bunch of great help desk techs that have real potential! Thanks for the great comments and for watching!
hi mr can you help me
You can contact me via the email in the video description
lol good jokes on this one
Thanks for watching!
