Snow Leopard can't join in Windows domain correctly
 

#1
Hello.
I joined iMac Snow Leopard into Windows domain but sometime I can't logging into OS X via my active directory username. iMac show me my domain name with a green button that mean joined correctly but I must Unbind it and Bind again for work.

What is your idea?

Since you are able to login to the domain successfully, that would indicate that your configuration is okay.

Have you asked your domain administrators?

I did find this article (search string: "mac occasional login failure windows domain"): http://www.macwindows.com/Fix-AD-dot-local-domains.html
