Random PC's cannot see random other PC's on network
Hello,
First try at posting a question.
Let me begin by saying that I am not an IT professional even though I have found myself being exactly that for the small company I work for. I’m just a computer geek that knew how to build custom PC’s (originally just for myself) and knew more about the functioning of computers than anybody else in the office. Now I find myself responsible for a network of 8 computers (soon to be 10), which on a whole I seem to be able to manage fairly well. Having said that, there is one stubborn, on-going issue that I just cannot figure out, and hopefully someone can enlighten me on the cause.
First let me describe briefly the setup:
- 8 custom built PC’s (various brand components)
- 6 Windows 7 Pro x64
- 1 Windows 7 Home x64
- 1 Windows 10 Pro x64
- Netgear ProSafe 24-Port Gigabit Switch (JGS524E)
- ASUS Dual-Band Wireless-AC1900 Gigabit Router (RT-AC68U)
- Fairpoint (local phone co.) Fiber Internet
- All 8 PC's on work network with same name
- All 8 PC’s wired to Netgear switch with fixed IP’s (192.168.1.XX)
- All 8 PC’s running basic version of AVG or Avast
- All 8 PC’s running Windows Firewall
The basic issue I am having with the network is that random computers cannot see random other PC’s on the network. There is seemingly no decipherable pattern to this, but it is constantly occurring in some configuration. The funny thing is that if I try viewing the network PC's by clicking on "Network" in the start menu, this problem occurs. However, if I try viewing the network through right clicking on network icon on bottom right of taskbar, open Network & Sharing Center, & click on "See Full Map", I can see all of computers. But, the PC's I could not see through the "Network" start menu link, I cannot access by clicking on them.
I have tried countless tweaks I have researched on the web, but no success. Regretfully, since I am not a trained IT pro, the depth of my understanding of the inner workings of a network limits my ability to problem-solve.
I have done many of the basic checks such as:
- Reboot all PC’s
- Restart switch & router
- Ensure all PC’s have same workgroup name
- Ensure all PC’s have unique fixed IP address
- Ensure all PC’s have same default gateway & subnet mask
- Ensure all PC’s have network discovery turned on
- Ensure all PC’s have file and print sharing turned on
- Ensure all PC’s have password protected sharing turned off
- tried unchecking IPv6 in adapter properties
- Too many more to list
The latest idea I’ve been working on is the DNS settings. Our internet provider gave me specific DNS servers to reference which I entered in each computer, but I read that perhaps I’m supposed to point to the router on each PC and only enter that info in the router admin. As I said, I’m way beyond my pay grade at this point, so I’m sort of poking in the dark for solutions.
Any ideas?
More than happy to provide any further info as needed…just didn’t want to get too long winded on original post.
