20 to 30 % of 2008 machines were be re-imaged were not completing do to auto logon failure. There where 2 separate conditions. One was the administrator account name was changed to root as per GPO but the password was never changed to match the password. The other condition seemed that no combination of possible administrator account names with any of the possible passwords were working. Following the logon failure for the first condition, after log in with the mentioned credentials the install would complete with any other apparent issues. With either condition, if the machines Domain account was deleted prior to installation the next install would complete without issue. Results on additional installation varied. We disabled the root name change in the GPO and add a security template import into the production task sequence. The template import changes the administrator name to root. The template is generated by setting up a local security policy to change the name and exporting the policy to an inf file. In the tasks sequence the inf file is copied locally and then imported using a secedit command. After multiple re-images across two machines either condition has not occurred. We suspect that the issue was being caused by caching on the a DC with the machines domain account. We haven't investigated further because we have an apparent fix, and we are moving away from domain management of machines. Q: Do you have anything to add? We suspect there was some caching issue with the individual domain accounts
