make sure you changed the `/etc/krb5.conf` and also you exported the ticket

evil-winrm -i frizzdc.frizz.htb -r frizz.htb

P.S : On public instance this lacking...

But once you have the ticket you can also access ssh since it's open using the same ticket

ssh f.fizzle@$IP

Try them on a private instance using release arena vpn, the regular ones seem problematic also make sure you updated your `/etc/krb5.conf` file

There's a 7z file in Recycle Bin that contains the password for M.Schoolbus. The user has WriteGPLInk perms over Class_FRIZZ and DOMAIN CONTROLLERS. Haven't looked into exploitation yet

I can't access that directory for some reasons, can you share the pass ?
