Windows 7 image - not sys prepped
Today I had a Windows 7 PC with a borfed HD. Putting a new HD in I then used Clonezilla to deploy an image stored from what I thought was this PC after it's last rebuild. Turned out I was wrong and it was actually from a similarly named client. The image went on fine and joined the network ok and I have since renamed the workstation. What problems am I likely to run into because the image was from another Windows 7 machine that had not been sysprepped?
Secondly would I be now better off building an image to hold on one of our 2008 R2 servers - if so using what?
