I run W2K with AD and I have a member server logging into
the domain. In the member server I have blocked all
unnecessary ports accoung to this article -
http://www.microsoft.com/technet/treeview/default.asp?
url=/TechNet/prodtechnol/windows2000serv/reskit/tcpip/part4
/tcpappc.asp

I have opened the domain and kerberos authentication ports
but still when I log into the domain, it takes very long
time for me to log into it. It takes about 5 minutes for
the log in process but it works. Has anyone experience
this before? and if so what specific ports can I leave
open?

Thanks
