I have a W2K3 functional level domain. In doing some housecleaning of legacy/unneeded accts in AD, I noticed the krbtgt acct. In brief research, I found that it is what I suspected...an acct used by Kerberos. But, from what I've read, it was used in W2K domains. My question - is it still used in W2K3 domains? I assume yes, but wanted to verify. Any documentation/link for verification would be great.
