“The hash value is not correct”

Here is another error related to Task Sequence and MDT 2008. After creating and advertising a task sequence, most probably you will run it :). Make sure you have the latest version of your packages on the distribution point, otherwise you will receive an error while running the task sequence. This will be something like “Task Sequence: your task sequence name has failed with the error code (0x80091007). For more information, please contact you system administrator or helpdesk operator.”

In the log file you will find this: “The hash value is not correct.”

What you can do to resolve this? Two  things:

  1. to update your distribution point with the latest version of the packages. To be sure the package was updated successfully, you can put a txt file somewhere and verify if it is on the DP.
  2. modify the advertisement to not download the files locally but access the files directly from the DP, although I’d not recommend it.
