The domain user was added to local admin group but that does not mean that had automatic admin privileges.<br />After 4 days inside asmca.log there was an error (ORA-12638….).Booooom…Kerberos authentication problem…<br />I try to change SQLNET.AUTHENTICATION_SERVICES= (NTS) to SQLNET.AUTHENTICATION_SERVICES= (NONE)…<br />But every time i was hitting the retry button the installer was reverting the value on the file sqlnet.ora to (NTS)…<br />So i decide to run the installer as local administrator…..<br />BOOOOOOOM….. Finally the installation of grid 11g r2 ended with no errors!!!!!!!!!<br />Just a couple days i was reading about the same problem (i cannot remember the site) and someone suggested<br />to add the DES ciphers to “Network security: Configure encryption types allowed for Kerberos” inside<br />“Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\Security Options”…<br />I have not tried that solution yet, but if someone is willing to try please let us now….Anonymoushttps://www.blogger.com/profile/18046460985219984814noreply@blogger.com
