About this tag
Network errors in Windows can appear as Wi‑Fi connection failures, file sharing access problems, or synchronization issues in enterprise environments. Common scenarios include the "Windows can't connect to this network" message when joining Wi‑Fi, error 0x80070035 when accessing network shares from a Windows Server, and "Could not connect all networks" on startup. Troubleshooting often involves checking saved Wi‑Fi credentials, adapter drivers, DHCP/IP settings, router security modes, firewall rules, and the Windows networking stack. In WSUS environments, synchronization failures may stem from unreachable Microsoft update endpoints. For home networks, permission settings and network discovery can cause inaccessible drives.
