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
