Therefore, you need to configure the mapping between the hostname and IP address on the Windows host. Perform the following steps:</p>
<p id="mrs_01_2075__p5855183012244">Modify the <strong id="mrs_01_2075__b126631012195">C:\Windows\System32\drivers\etc\hosts</strong> file on the Windows host and add a line indicating the mapping between the host name and IP address, for example, <strong id="mrs_01_2075__b52680106193">10.244.224.45 10-044-224-45</strong>. Save the modification and access the host again.</p>
