dns lookup and lan connection

[Mary]

one of our user has problem when he is using nslookup hostA(this hostA is in our intranet) when he is in the LAN,

but he can use nslookup hostA in office wifi (wireless network) , we have company proxy (intranet as well as internet), so any idea how to troubleshoot?

does wifi and LAN  using different DNS server to resolve, how to configure this in local laptop and network?

Hello,

WiFi and LAN use whatever DNS server you have configured.

Issue the command 'nslookup' from the command prompt at both locations, this will give you the DNS servers that are being used.

nslookup shows DNS server: unknown in LAN

Hello,

what is the output of 'ipconfig /all' at both locations ?
