Professional suddenly won't connect to an instance

[Jackson T. Cole]

I have Project Server 2003, SP1, running against 3 database instances - my
normal EPM, the MS "Sample" demo, and a sandbox instance. Today, when I tried
to connect Professional to the sandbox I get the following error:

---------------------------------------------------------------------------------------------
Operation failed - You are attempting to connect to a Microsoft Project
Central Server which is not supported by this version of Project.
----------------------------------------------------------------------------------------------

PWA will connect OK, display a task view, edit and save the usual
Enterprise fields. The OLAP cube builds OK. Both other instances are OK.

To my knowledge, I have done nothing to sandbox to cause this. The last
connection was on 11/9 to backup Global. Before that, I had changed the
graphic in IIS that appears in the upper-left on PWA.

I've got my MSCE and DBA poking around, but I would like to know if there
are one or more root causes for this error. I can't recall anything in the
last couple of weeks that I did in the sandbox that would be this
significant. I NEVER do anything directly in the database myself, and have
threatened the DBA with loss of a part of his anatomy if HE does without me
looking over his shoulder! :>)

Need some hints as to where to look.

Thanks!

Never mind. I discovered something I did a couple of weeks ago, and it
probably screwed up Professional's connection to the web site. I will
re-post in the Project Server section, as it involves IIS.
