XP Peer to Peer woes.

Currently have a desktop and notebook, both are running WIN XP Pro. I can see the notebook on the desktop but not vice-versa. Also, if I click on the notebook’s icon in my workgroup I get the following error: “\\XXcomputer_name is not accessible. You might not have permission to use this resource. Comtact the administrator of this server to find out if you have access permissions.” I also get a similar error when I click on “view workgroup computers” on the notebook.
