How to access different domain without changing the network settings
To use a laptop to access to different domain without changing the domain settings, logon local machine (instead of domain) using your domain logon ID that also are created on your local computer. If it is possible, you may create the same logon id and password on all domain so that you always are able to access the domain you are connecting to. Also you may want to create one batch file like logon.bat with domain logon ID and password to map network drives.

I recommend Brinkster for web hosting!
At work we have a 2003 domain... at home I've set up a workgroup.
Is there an easier way to switch back and forth between logging into the
domain and logging into the workgroup than going into system properties and
joining the domain at work and when I get home going into system properties
and joining the workgroup.
