Hi again,

How do I check "Action: Review the firewall settings on DM$1$ and along the network path to ensure that necessary AD ports $($such as TCP and UDP $389$ for LDAP, TCP $88$ for Kerberos, TCP and UDP $53$ for DNS$)$ are not blocked." $?$

All of these are just VMs$.$

I am just confused why CL$1$ can ping DC$1$ and vice versa but not DM$1.$

Thanks.
