If the client computer has no connectivity to the internet or windows network domain, what are the commands to fully reset the network adapter and related cache, services, etc.?
Assuming the client is running recent version of Windows... open an elevated command prompt and try some of these. I usually never need to go past the first four ipconfig commands.
flush and register dns, release and renew ip
ipconfig /flushdns ipconfig /release ipconfig /renew ipconfig /registerdns
flush arp cache
netsh interface ip delete arpcache
get nic list and index
wmic nic get name, index
disable nic with index number (4 as example)
wmic path win32_networkadapter where index=4 call disable
enable nic with index (4 as example)
wmic path win32_networkadapter where index=4 call enable
example stop and start Windows service: "DNS Client"
net stop "DNS Client" net start "DNS Client"
Admittedly, when it comes to the list of services, I'm not sure which ones you'll need to look into but I give one example of how to stop and start them.
