Active Directory Recon

Enumeration from a non-domain joined Windows computer

Note:

Login as a local admin user and configure your system DNS server to be the IP address of a domain controller in the target domain firstly.
(Control Panel > Network and Internet > Network Connections > Ethernet Properties > IPv4 Properties)
So that you can resolve the target domain.

ping unsafe.local
nslookup unsafe.local

After the below runas commands, you must check to access SYSVOL and NETLOGON folders with the following command:

net view \\unsafe.local\

You must see the SYSVOL and NETLOGON folders if you supply a valid password for the "runas" command.

Nslookup

#For finding DCs
C:\> nslookup
   > set type=SRV
   > _ldap._tcp.dc._msdcs.unsafe.local
   
#To find all of the available records
C:\> nslookup -type=any unsafe.local

Gpresult

#Displays verbose policy information for remote computer
gpresult /v /s target-IP /u username /p password /scope computer
gpresult /z /s target-IP /u username /p password /scope computer

#Displays RSoP summary data for remote computer
gpresult /r /s target-IP /u username /p password /scope computer
