Let me know if you want any additional information or want me to try anything. These are VMs so I can spin them back up quickly if I brick one.

I can do a cifs mount to the GPT.INI file and open it just fine but Adsys and Smbclient will fail out trying to hit those directly. I did notice smbclient works when using the -D flag....smbclient //example.com/sysvol -D "example.com/policies/{policy}" Without that flag (smbclient //example.com/sysvol/example.com/policies/{policy}) it comes back with tree connect failed: NT_STATUS_BAD_NETWORK_NAME Case matching doesn't seem to make a difference for me. I thought it was a client side configuration problem and have been tinkering with SMB.conf but I had not gotten anywhere.
