We have been having this random issue where clients can: connect to the VPN (Meraki MX##, domain authentication, PSK, split tunnel, IPv6 disabled) Ping servers on the network via IP or DNS name Query the DNS server via NSLOOKUP attach via RDP to any computer on the network BUT they cannot access network shares.  Eventual error (after about 10 minutes) is:  An error occurred while reconnecting to \\networksharename Microsoft Windows Network: The local device name is already in use The connection has not been restored   In all cases the client is a fully patched Windows 10 Pro client and the Server a Windows 2016/19 (fully patched). We have sometimes seen where the client attaches to a different remote network, it will work   We have already done the following with no success: recreated the VPN tunnel tried different/new user profiles on the client system tried split tunnel on/off Turned the firewall (and anti-virus) on the server off Enabled SMB v1 It should be noted that: Server and client sides have different subnets We've done this 100s of times before Have other clients on this and other networks working without issue So we have some idea what we're doing You help would be appreciated   Regards ...
