Read the error literally
«Access denied», «network path not found» and «no permission» are three different faults. Path-not-found means name resolution or a dead server; access-denied means you arrived fine and were refused. Copy the exact text before doing anything — it halves every later step.
Rights, not the network
Nine times out of ten the network is fine and the account lacks rights on the share or the NTFS folder beneath it (both must allow). Check with which account you are actually connected — Windows silently reuses cached credentials from last year — and ask the owner for the group name instead of «give me access to everything».
Off-site changes the rules
From home the share only exists inside the VPN tunnel: connect VPN first, then open the folder. Split-tunnel setups add one more trap — corporate addresses must go through the tunnel, not the home router.
Offline files conflicts
Windows offline copies let laptop users work disconnected, then sync — and conflict when both sides changed. The sync center shows the collision: keep the newer, keep both with renamed copies, but decide per file instead of clicking through. Chronic conflicts mean the workflow needs SharePoint versioning, not sneakernet sync.
Server moves and renames
Mapped drives by server name die on every migration; mapped drives by DFS namespace survive them. After any move, remap with the namespace path, update login scripts once centrally, and keep the old name as an alias for a quarter so stragglers fail loudly instead of silently.
