I'm having trouble accessing an SMB share from my Windows Server 2025 machine that's set up for Veeam Backup & Replication. The environment includes HPE GreenLake for File Storage with a NAS system that's accessible from a Windows 11 laptop, but my server can't connect. When I try to access the share, I get an error saying, 'The specified network name is no longer available.' I've done a bunch of troubleshooting, including checking the connection to the NAS, ensuring TCP port 445 is open, and disabling the Windows Firewall, but I'm still stuck. Any ideas on what could be wrong?

Try accessing the share directly using its IP address, like \192.168.45.10sharename. If that works, you might need to tweak the DNS search order in your network adapter settings on the server. If it doesn't, consider granting read permissions to the share root for the server's active directory account. Also, check your network settings to prefer IPv4 over IPv6—there's a guide here if you need help with that.
Have you enabled insecure logins for SMB on your server? It's necessary for compatibility with certain configurations. There's a Microsoft guide that covers how to enable that if you haven't already done it.
I noticed you have several NAS VIPs. You might want to check the one your laptop successfully connects to. Try to ping it from the server and see if there's a response. If it's not responding, try getting the server and laptop onto the same VLAN to test access. Running "net view" in the command line on the server might show if you have any shares already mapped incorrectly.
