The same NAS is accessible by IP but not by name

Possible solutions

Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.

1. Address and name comparison

   Confirm that both paths lead to the same NAS.

   Steps to follow

   1. Check your router's client list or NAS screen for its current local IP address.
   2. In the file explorer, compare the path by IP and the same share by NAS name.
   3. If it works by IP, write down the exact name error and check if the NAS name has been changed recently.
   4. At the command line, the nslookup command with the NAS DNS name can show what address it resolves to; Simple local discovery names do not always use DNS.

2. Local name and address management

   Fix the source instead of making random posts.

   Steps to follow

   1. Check that the PC and NAS are connected to the same valid local network, not an isolated guest network.
   2. On the router, according to its instruction, assign a DHCP reservation to the NAS so that the IP does not change arbitrarily.
   3. If local DNS is used, correct the NAS name entry in the administration site according to the reserved address.
   4. After updating, check the name again. Do not use a manual host file entry unless you anticipate a future address change.
