>>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.

In that case, I think you are SOL. The only way I know of to access multiple domains is for them to be trusted between each other. That way, when you access one of the domain controllers to get a list of available domains to pick from, the domain it controls is displayed as well as all domains it has truted relations to. Unless your clients want to trust one another, it won't work.

Another thought just came to mind. If you set your W2K laptop up as a domain controller (a domain all to itself) and had trust relations with all your clients, you could log int to your laptop locally and still have access to the domain you were currently connected to.

The network admins would have to add you domain\user to the appropriate groups on their domain and then you should be able to access domain resources (including SS) without any problems.

Just a thought.
