I work for a large hospital. There is a standard Windows 2000 disk image
designed for workstations deployed in patient areas. This image is
installed on nearly all new desktop systems, including those used to
administer TSM and other centralized infrastructure. I recently had a
Windows Administrator install Operational Reporting on my desktop system.
I was initially unable to set up reports; Operational Reporting kept
telling me I needed to enter a TSM administrator ID and password, even
after I had entered that information repeatedly. I was able to set up
reports after a Windows administrator changed some permission settings.
I never at any point got an error message telling me that Operational
Reporting was unable to save the administrator information.

I am now trying to resolve a similar problem with mail server information
needed to e-mail reports. Here again, I have never gotten any error
messages about problems saving the information. Operational Reporting
claims to save the information successfully, but is subsequently unable
to retrieve the information.

It would appear that the developers made a policy decision that it was
unnecessary to check the success of attempted registry updates.
