Windows – How to access a locally-shared folder via UNC path when not connected to a network

I can confirm that the "Microsoft Network Client v.3.0 for MS-DOS" on MS-DOS 6.22 can connect to a Windows 7 machine. I dusted off an old 486-machine with this client still on the harddrive.

I also got a error 53 trying to connect to a Windows 7 machine. (Even NET VIEW \\MACHINE_NAME gave the error 53.

I needed to adjust the LMHOSTS to include the machine-ip address.
(adding 192.168.1.33 MACHINE_NAME to it).

After that i got an error 5: Access denied. I changed the following with gpedit.msc in Windows 7:

Network security:
LAN Manager authentication level: Send LM & NTLM - use NTLMv2 session security if negotiated
Do not store LAN Manager hash value on next password change: Disabled

You already did the first line but you need the second too (setting it to "Disabled").

After that i created a new user with a password (you can probably change your user but you need to change it or else it does not work).

After that i got an error 1: An internal error occurred on the NET VIEW \\MACHINE_NAME but i could create a driveletter with NET USE P: \\MACHINE_NAME\SHARE and access all its files.

So if you are using the same configuration (Network client and DOS-version) you should be able to get it working. Hope this helps.

I've seen the exact same issue when connecting to a private network i used to support. Check the configuration of the VPN connection. The default configuration is "Use default gateway on remote network". Since the remote network does not know how to get to your local resources or resolve the names, you PC fails to connect.

This is an old article but describes the same behavior: https://support.microsoft.com/en-us/kb/317025

If you are using the Windows 7 VPN client - Open the properties of the VPN connection, select the Networking tab and Properties if the "internet Protocol Version 4 (TCP/IPv4)" connection - Click the Advanced button and on the "IP Settings" tab uncheck the "Use Default gateway on remote network" box.
