Windows 10: Do not have permission to access another computer on my wireless network

I have 3 computers on my wireless network - 2 laptops and one desktop. I can access the desktop with one of the laptops; but when I try to access the desktop with the 2nd laptop I get a message that I do not have permission to do so.

Permission to access network

Hi Kristen,

You might be experiencing this issue because you lost permission to access the network resource or shortcut after upgrading your computer. To better assist you with this problem, we would like to know the following information.

• Are you using the shortcut to access a file or folder located on another computer in the network?
• Is the file or folder located on the computer that you recently upgraded?
• What is the exact error message that you received when accessing the shortcut?
• Are you using a homegroup to share files between devices on your local network?
• What troubleshooting steps have you tried so far?

In the meantime, let's run the Network troubleshooter. This troubleshooter finds and fixes common connection problems. Here's how:

• Click Start.
• Start typing Network problems, and then select
  Identify and repair network problems in the results.
• Follow the steps in the troubleshooter and see if that fixes the problem.

If you need further assistance, please do not hesitate to post a reply.

 

Wireless Network

Thanks for trying the steps again. It's now clear that the problem is on your router. To reconnect your laptop to the network, we suggest that you set or specify the channel of your wireless network. If you can access your router's user interface, set the
channel to either channel 1, 6, or 11. Once done, remove your WiFi network from your preferred network list, then reconnect.

Let us know the result.

Regards.

 

One computer cannot access other network computers.


So I've tried every troubleshooting step I know:

• Double checked that Net Bios was enabled
• Ran a bunch of network commands:
  • flushed DNS
  • registered dns
  • pinged and located the named computers successfully
• Reset my router to factory settings

Nothing works when I try to access via explorer. I'm still baffled by the fact that every other computer can access each other AND access this computer. It's just the outgoing connection from this machine that doesn't work.

Any thoughts?
