Local Client can’t resolve hostname..

Totally new to AFP and DNS config so thanks for bearing with me.... I have successfully installed and configured (I think) Leopard 10.5.6 on my xserver. I followed and checked many of the DNS tutorials on line that help me to configure it correctly coming from a dynamic IP address from my local ISP... I checked the DNS settings using the changeip command. Here are the results. server:~ test$ sudo changeip -checkhostname Password: Primary address = 192.168.1.100 Current HostName = server.myhouse.com DNS HostName = server.myhouse.com The names match. There is nothing to change. [b] here is the question....[/b] On one of my client computers on my network, I can afp://[fixed ip address of server] and everything works great! If I afp://server.myhouse.com nothing works and kicks the error message... "The Finder cannot complete the operation because some data in "afp://server.myhouse.com" could not be read of written. (Error code -36) Is this a permission issue? Thanks so much in advance darnelld
