Windows 7 Domain PC cannot connect to shared folder on Windows 2019

1. To get this working for my Windows 7 client PC’s, I ran this PS Script on the server:  Set-SmbServerConfiguration -RejectUnencryptedAccess $false

2. Go to “gpedit.msc” to configure “local security policy” on the Win7 client, change “LAN Manager authentication level” to “send LM & NTLM -use NTLMv2 session security if negotiated”.

Local computer policy > Computer configuration > Windows settings > Security settings > Security options > Network security: LAN Manager authentication level > send LM & NTLM -use NTLMv2 session security if negotiated

3. If the issue persists, please also check if there’s any error message in the event viewer regarding SMB on server side.
