The problem: Within my Virtual PC with Enable Integration Features turned on I get a login dialog that I cannot successfully use to login. If I disable integration features, I can use the Virtual PC. Now for a bit of history. This is on my work PC with a fresh copy of win 7 ultimate logged into a corporate domain. Main OS is 64 bit win 7 ultimate. I am logged into the corporate domain and I have admin rights to the PC. The virtual PC file was created on a win XP box and copied to my new drive. I upgraded the integration features which ultimately requested login credentials. The credentials had my DOMAIN\username. I entered the correct information and from point on couldn't get past the next 'old school' login prompt. I have it working just fine with the "enable integration features" turned off but as soon as I turn the "feature" on, I get a black screen with a standard login window that doesn't seem to go against the corporate "Active Directory" or my local PC user accounts. I have updated the virtual PC to the latest win xp service pack 3 with all the fixes. The only thing I haven't installed is the .net 3.5 packages... I do have XP mode installed with a different virtual disk working and updated. It works fine with integration turned on. Can I provide any other details to help track this down? Any advice is greatly appreciated. -Razor

I apologize if this is in the wrong forum. Should this be moved into the Windows 7 virtualization forum? I had thought since my issue is with logging into the corporate domain (within the Microsoft virtual pc window) that I should post here. What do you think? -Razor

I have this exact issue and I also do not want to make VPC a domain user. I am using the IE Application Compatibility VPC Images. http://www.microsoft.com/en-us/download/details.aspx?id=11575 I tried the steps the OP listed in setting a strong password, but that doesn't work for me. I did that, and still when I try to enabled the enhanced features I get a domain login window. I don't want these VMs to connect to the domain. I've used these images for many years outside of a domain, and they work fine. But now I'm stuck because they always try to use the domain login for enabling the enhanced features. How can I get Windows 7 to stop trying to use the domain login? TIA
