a. Use Set-SmbServerConfiguration -EnableSMB1Protocol $true or false powershell command for enanling/disabling SMBv1.
Run SeT-SmbServerConfiguration to enable/disable SMBv2/3. Note: When you enable or disable SMBv2 in Windows 8 or Windows Server 2012, SMBv3 is also enabled or disabled. This behavior occurs because these protocols share the same stack.

Situation: The client is migrating their DC, DNS and DHCP. The problem they are facing is they don’t have a detail inventory to show which network devices are using Statics IP address and DNS.
Resolution: Use network monitor to check destination IP addresses, age-out so that we can find out which devices are still accessing the old DNS IP addresses. In our example, we run Paloalto Firewall Monitor, add destination DNS IP address 10.0.0.85. It shows GloablProtect Zone still uses this DNS IP address.
Situation: The client has a Paloalto Firewall 850 running GloableProtect. Recently, they change their internal DNS. They would like to know how to change the DNS on the GloableProtect.
Login Paloalto Firewall.
Go to Network>GloablProtect>Gateway.
3. Click on Gateway under Name.
4. Go to Agent and then Network services.
5. You have options to change the DNS and WINS.
6. Still in the Agent, click Client Settings and end users.
