The Question is:
We've lost our SYSTEM account password and need to know how it can be reset.
The Answer is :
If you have another username with write access to the OpenVMS system
authorization file through privileges or through file protections or
an ACL, you can use the following commands:
$ set process /privileges=all
$ set default sys$system
$ run authorize
If you do not have another username with access to the authorization
database, please consider a review of the OpenVMS Frequently Asked
Questions (FAQ) document or the available OpenVMS system management
documentation. You will find that the OpenVMS FAQ contains the answer
to this question as well as to various other questions, and you will
find that the emergency system startup section of the OpenVMS system
management documentation also contains details on this topic.
