You are the computer specialist in a small business. Your company server is named FS1 and has an IP address of 10.0.0.2. The hardware in your company server started to experience intermittent failures, so you transferred the shares on the server to a spare server and took the main server offline. The spare server has an IP address of 10.0.0.3. You edit the existing A record for FS1 on your company's DNS server and redirect the hostname to the spare server's IP address of 10.0.0.3. Afterward, most users are able to access the shares on the spare server by hostname, but several users cannot. Instead, they see an error message indicating that the FS1 server could not be found. Enter the command you can run from the command prompt on these workstations that will allow them to access the shares on FS1 without performing a full restart. ________________________________________
