I brought my own laptop PC into a business I joined, and they registered the laptop to their domain and upgraded my Windows 7 Home to Ultimate. It was a temp assignment, now I've left the company fo another assignment, but will work from home. I've upgraded my family PCs to Windows 7 to create a homegroup network, but I can't join this homegroup with my laptop PC, as I'm prevented from doing so while the laptop is apparently still on the domain. How can I remove my laptop from this domain, since it doesn't apply any more?

Do you know the local computer administartor password? If not, can you change it or enable it if it is disabled. Then select Proeprties of the computer>Advanced System Settings. Under Computer name click Change. You can change the domain to workgroup or whatever haomegroup name you give.Bob Lin, MS-MVP Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Setup Windows, Network, VPN & Remote Access on http://www.howtonetworking.com
