Yup, affraid so. Some decrypt around 24 hours, some have taken longer than 3 days!
Thanks for the reply pierce, as long as that's normal I can live with it, just wanted to check if this was an excessive amount of time incase we are doing something wrong.
Sorry just thought of something else, instead of decrypting could we just re-image? We use SCCM to image our laptops, would this still be possible to do with it still encrypted? We only have one primary partition on our laptop set-ups which are being encrypted.
Of course, you only use the CD based decryption when there is something on the drive and encryption/OS is broken.
If you need to decrypt a working machine there is a policy you can apply that will do it as quickly as it encrypted.
For a machine to be rebuilt our deployment tool just wipes the harddrive and away it goes. as far as its concerned its an unformated drived (because of the encryption)
