Neverfail for IIS AM(X) and the limitations of administering local users.

Follow

Summary
-------

Neverfail Heartbeat does not currently support the replication of user accounts from active to passive servers. This imposes several important restrictions upon the Administration of an IIS Web Server once Neverfail Heartbeat has been installed because the Secondary Server is a clone of the Primary, it must have identical user and group information.

- The creation of new users is not supported. This includes the following
- New POP3 users.
- Creation of new POP3 domains. Refer to Knowledgebase Article 365.
- New users for the purposes of FTP or HTTP services.
- Changes to group permissions are not supported.

These tasks all need to be performed before Neverfail Heartbeat is installed. If any of the above Administrative tasks need to be performed then the system will need to be cloned again.

Do NOT run Microsoft's IIS Lockdown Tool. This should be done prior to installing Neverfail Heartbeat with IIS Server AM(X).
