Hi everyone,

Is it possible to make a computer in a workgroup to "talk" with a
server/computer that belongs to a domain using IPSec.

I'm not talking a bout VPN, both machines are in the same physical network
and authentication using certificates isn't a option, so all I can use is
Kerberos.

Not going to work. Computers in a workgroup do not do Kerberos
Your only two choices are shared secret or certificates
Why are certificates not an option?

That's what I thought
I've been told that creating a IPSec policy and configuring that IPSec
policy in some servers in domain using only AH (Authentication Header) using
Kerberos authentication would work for comunication witrh XP machines not
members of the domain.
Does this sounds correct for you?
Thanks for your time.

Wow. Whoever is telling you this must be on some really good drugs!
Non-domain computers cannot do any kind of Kerberos communications at all.

eheheh...

Thank you for your time...
But we never know when something strange is possible, so is better to ask
than try to do stupid configurations.
