I have a Acer Extensia 5630 that I had to clone from another laptop (same model).
I used RDeploy for windows (part of Altiris) and once the image had been loaded it asked to change the computer name and other details. All I changed was the computer name. Once the laptop was on site we found out it could not pick up a dhcp address. Once a manual IP was set we tried to join the domain without success, and this led to me using Microsofts New SID v4.10 (http://technet.microsoft.com/en-us/sysinternals/bb897418.aspx
) to change the SID to a new random number.
The laptop still cant join the domain. I don't have the exact error message at the moment but the only pointer I read in regards to it said to check you gateway server which was fine. the message says something like the domain can no longer be contacted.
