[TD="class: alt1, bgcolor: #F6FAFB"]Running Windows 7 Ultimate 64bit on a Tosh laptop. Everything fine until a few days ago and NOTHING changed by me (new installs, configs, etc). My NAS drive always appeared as 'DISKSTATION' under 'Network' in Windows Explorer. Then it just disappeared.

I have since noticed the following:

- No change at all on my other networked PC which runs the same OS
- The drive is connected, live, accessible - just not appearing in the Explorer window
- If I put a shortcut to the drive on my desktop, it works every time despite the drive still not appearing in the 'Network' section of Windows Explorer
- When I tried to diagnose using "Net View", I got a failure and system error 58.

Seems like something has gone wrong with the networking subsystem on this particular machine, despite my not touching anything or changing anything. The other machine remains fine, works as it always did, 'DISKSTATION' appears in the Windows Explorer window, etc.

The only thing I could thing is maybe a Windows update caused it - but the last Windows security update was a few weeks back, and the problem randomly started yesterday (or the day before).

Plenty of people want to tell me I need to change LAN manager security settings etc BUT seriously, nothing changed since it was working, so how could a reparameterisation be the answer?

I am worried that the Net View failure is indicative of something more serious wrong.

Any ideas out there?

Thanks...

It seems like you are experiencing an issue with your NAS drive not appearing in the 'Network' section of Windows Explorer on your Windows 7 Ultimate 64-bit laptop, despite it being connected and accessible. Here are some steps you can try to troubleshoot this problem: 1. Check Network Discovery Settings: - Ensure that network discovery is turned on. You can do this by going to Control Panel > Network and Sharing Center > Change advanced sharing settings, and make sure that Network Discovery is enabled. 2. Restart Network Services: - Restart the "Function Discovery Resource Publication" and "SSDP Discovery" services. This can be done by typing services.msc in the Start menu, locating these services, right-clicking on them, and selecting Restart. 3. Flush DNS and Reset TCP/IP: - Open Command Prompt as an administrator and run the following commands:

 ipconfig /flushdns netsh int ip reset

4. Check Firewall and Antivirus Settings: - Temporarily disable your firewall or antivirus software to see if they are blocking the NAS drive's visibility. 5. Re-map the Drive: - You can try mapping the NAS drive again to see if it appears in Windows Explorer. Right-click on 'Computer' or 'This PC', select 'Map network drive', and follow the prompts to reconnect to the NAS drive. 6. Update Network Drivers: - Check if there are any updates for your network adapter drivers. Outdated drivers can sometimes cause connectivity issues. You can do this through Device Manager. 7. Check Event Viewer for Errors: - Look in the Event Viewer for any related error messages that might provide more insight into the issue. To access Event Viewer, type eventvwr.msc in the Start menu. If after trying these steps the issue persists, it might be worth considering a system restore to a point where the NAS drive was still visible. This could help revert any changes that might have caused the problem. Regarding the "Net View" failure with system error 58, this could be related to network connectivity issues as well. The suggestion about LAN manager security settings is relevant in some cases, especially if there have been recent Windows updates that may have impacted these settings. Feel free to try these steps and let me know if you need further assistance!
