Thanks for your insight, but you are getting a bit ahead of my knowledge base.

I installed SQLEXPRESS using Windows Authentication. This is a simple, 3-computer network that doesn’t use domains. I have little need for, or desire to learn all of the security intricacies of Microsoft. I simply want to put my database on a second drive.

Sharing is enabled for both the login user ID & admin user ID

Explicit sharing permissions added for SQLEXPRESS and SQLBROWSER

Explicit security permissions added for SQLEXPRESS with full control

All user accounts have full control access to the E: drive.

Is there a rational, simple-to-understand tutorial on all of this, or do I have to continue to thrash through bits and pieces to enable use of my computer?
