Application pool being disabled

P: n/a
I have 2 web servers on which I am running a .net version 2 application, both
of which I want to use an application pool with the same domain user's id and
password to tighten security. I have this working fine on one web server
(http), but keep getting the error below on the other (https). I cannot see
any difference in how I have set up the application pool, and the messages
below do not shed any light on the matter. Can you help me locate what the
issue is? Thanks. The error message follows (the link below didn't help at

The identity of application pool, 'SBAApps' is invalid. If it remains
invalid when the first request for the application pool is processed, the
application pool will be disabled. The data field contains the error number.

The identity of application pool 'SBAApps' is invalid, so the World Wide Web
Publishing Service can not create a worker process to serve the application
pool. Therefore, the application pool has been disabled.

The account needs:
* "Log on as a service" (Local Security Settings -User Rights
* Membership in the "IIS_WPF" group (Computer Management -Local
Users and Groups)
* "Read & Execute", ""List Folder Contents" and "Read" permissions on
the codebase (Explorer -Properties)
* read/write access to the assigned temp area

I have also seen reference to (but never needed)
* start CGI processes: adjust memory quotas for a process and replace
a process level token
* access to the "Logon local" policy group

Watch out: the app-pool window in MMC does not auto-refresh; once an
app-pool has died it must be manually resurrected to try again.

Hope this helps; post back to let us know...

IIS_WPF should have read IIS_WPG... force of habit ;-p
