Eric,
You can set up your laptop to not log into the domain but a workgroup. By changing the workgroup when you visit the client, you will have access to their network provided you log in to each system that you want to access.

For example, you need to access the printer shared on PC2 and the data on PC1. You need to authenticate the workgroupname\username for PC1 and PC2. Using a domain login simply bypasses the individual authentication.

Changing workgroups is something you can do locally and you don't need the network admin to do anything.

HTH.
