i know some about computers, not much about networking (at all) and i can usally fix most problems i have, but this one
so ill set up what i got.
my problem is my main desktop(windows 7) cant see any other computers under my network tab, and my others computers cant see it.
the main desktop is connected to my gateway/router, 1 of my other computers are directly connected to my router, and another connected to a switch, which is connected to my router. those 2 computers communicate just fine...
they all have windows 7 home premium, the one that cant see the other computers, did not have windows 7 at purchase, i just recently installed home premium(all my others have home premium) onto it.
yes i have checked the setting about sharing, i have my drives shared, no passwords set, the same workgroup, discovery is on, and they all have internet access, and are successful at getting the speed im sold by my ISP.
there's one thing on my main desktop, when i open my device and printer windows, from control panel my PC has a yellow triangle and requires trouble shooting, and right click and select trouble shooting, it does its thing, and says that im missing a driver for PCI simple Communications controller, and it wants to install it(fix the problem), i click fix, it does its thing, and says it cannot install it and directs me to the stupid windows help window which offers no help.
thank you anyone who can try to help me resolve this issue, i really need to get my computer networked with my others.
