我关注了@vercelli的评论和这些建议: 我卸载了Oracle XE，以具有管理员特权的本地用户身份登录，在此安装了Oracle XE，它对本地用户起作用:

I followed @vercelli 's comment and this topic. Seems like you can't install Oracle 11g XE with an user account connected to the entreprise domain (installation process can't connect to the database). So, I followed these advices : I uninstalled Oracle XE, logged as a local user with administrator privileges , installed Oracle XE there and it worked on the local user:

.

但是当我重新登录为用户域时，我遇到了与以前相同的问题:ERROR: ORA-12638

But when I logged back as an user domain, I had the same issues as before : ERROR: ORA-12638

因此，我像以前尝试过的那样更改了域用户上的sqlnet.ora文件(在出现此ORA错误的不同论坛的建议之后):

So, I changed my sqlnet.ora file on the domain user as I had tried before (after advices from different forums who had this ORA error) :

SQLNET.AUTHENTICATION_SERVICES = (NTS)

到

SQLNET.AUTHENTICATION_SERVICES = (NONE)

现在它似乎也可以作为域用户使用:我能够连接.

And now It seems to work as a domain user too : I was able to connect.
