By default Active Directory will only accept local connections, meaning that the computer user will have to connect via VPN or Dialup prior to authenticating with the domain controller. The servers may still be pingable over WAN but AD should only ever communicate over LAN
have you changed the DNS settings on the user's machine at all?
When a computer tries to find a domain controller it uses a DNS record to find it. If it cannot find the correct DNS record or if host finds a different DNS zone by the same name this can cause problems with Active Directory
How it reaches the DNS server is important. If there are a bunch of network connections on the machine the routes could be a disaster
Also, I'm assuming this is a standard PC.... You should only have one network adapter listed under ipconfig /all.
If you are comfortable uploading that information here, run this command in command prompt "ipconfig /all >> C:\Users\%username%\Desktop\ipconfig.txt". That should create a text file with the ipconfig results. Copy and paste the contents of the "ipconfig.txt" file here. If it is showing more than one "Ethernet Adapter Local Area Connection" then that is likely a related issue and could be the root problem. If you can successfully remove all extra connections I would be willing to be you would be able to rejoin the domain.
Lastly, this is kind of a superfluous question as I know what the answer *should* be in a business environment, but your organization is running a good, up to date virus protection program, right? And this program hasn't discovered any viruses on the PC?
I couldn't waste anymore time looking for the issue, so I did reformat. It kinda sucks I wanted figure out issue.
I was able to connect domain and network folders on the servers.
Thanks everyone for troubleshooting steps
That was my next recommendation. With your description of "197 network network adapters" displayed after an "ipconfig /all" command, I was thinking something had been majorly corrupted or the PC had a virus. In any case, I'm glad your problem has been resolved.
We are having this at the moment.
Its down to the amount of Network Cards as well as USB devices being plugged in
You need to show hidden devices in Device manager after running At the command prompt, type in set devmgr_show_nonpresent_devices=1 and press Enter
Delete all your additional network cards.
This worked for me but it keeps coming back.
Need to find a proper resolution
