Hello @mrslouise_mccaskill

The error code 0x80070035 (“The network path was not found”) typically occurs when Windows cannot find or establish a secure connection to a shared resource like your \\McCazServ. This is common after Windows updates.

Did you machine recently pull Windows Updates?
Did you try Restart (not Shut down) machine?

• Access via IP Address: Instead of typing \\McCazServ, find the server’s IP address (e.g., 192.168.1.50) and try typing \\192.168.1.50 in File Explorer. If this works, you have a DNS/Name Resolution issue.
• Check Network Profile: Ensure your network is set to Private, not Public. Go to Settings > Network & internet, click your connection (Wi-Fi/Ethernet), and select Private.

Reset Network Settings
If configurations are corrupted, a reset can clear bad paths.
Open Command Prompt (Admin).
Type the following commands one by one, hitting Enter after each:

• ipconfig /flushdns
• netsh winsock reset
• netsh int ip reset

Restart your computer

In the newer Norton v26 interface, the menus have been streamlined. The old “Full Trust” setting is now essentially handled by moving your network connection into the Private list, which automatically enables file sharing and relaxes firewall restrictions.

1. Set Network to “Private” (v26)
This is the most critical step to allow your PC to talk to your NAS.

1. Open the Norton app and click Security on the left pane.
2. On the dashboard, click Smart Firewall.
3. Go to the Settings tab.
4. Next to Private networks, click Manage.
5. Find your network in the list and click Add to Private.

2. Add the NAS IP as an Exclusion
If the network is already set to Private but access is still blocked, you must manually exclude the NAS IP from being monitored.

1. In the Norton app, click Security > Smart Firewall.
2. Look for a section or tab labeled Exclusions or Traffic Rules.
3. Click Add to create a new rule.
4. Select Allow, then Connections to and from other computers.
5. Choose Only the computers and sites listed below and enter the specific IP address of your NAS.

3. Disable “File and Printer Sharing” Protection
Some users have found that v26 has an aggressive internal block on SMB/Samba traffic even on private networks.

• Check the Smart Firewall settings for a toggle specifically named File and printer sharing (Samba) protection and try turning it Off temporarily to see if access returns.

4. Verify with the NAS IP
If you are trying to access the NAS by its name (e.g., \\McCazServ), Norton’s firewall might be blocking the discovery process.

• Try accessing it directly via its IP address by pressing Win + R and typing \\192.168.x.x.

Important Note: If you are using the Norton VPN simultaneously, it may block local network traffic regardless of your firewall settings. Try turning the VPN Off to test if that is the culprit.

Do you know the IP address of your NAS, and have you tried connecting with it while the Smart Firewall is briefly disabled?

Caveat: I’m not NAS
