I have an old RAS (came free with Crystal 9, which we're still using:  ePortfolio LT).  I have a couple hundred reports hanging on it that my end users can access via IE, and that in turn access SQL2000 and SQL2005 databases.  Now I'm trying to add one more report that's going after a MySQL 5 db.  I have the same ODBC connection driver installed locally to my PC and to the server, both using the same login/password, but when I run the report from crystal (locally) I get results, when I run it from ePortfolio, I get this:

Help?

So far, no joy.  Best we can figure is we need to put a connection string in ePortfolio LT somewhere - but we can't figure out where.  There are several .cfg files buried in the ASP pages.  Anyone know which one?

(I can hit this from my workstation via crystal, but I cannot run the thing from ePortfolio - wouldn't that mean that I have AD rights but the ePortfolio server doesn't know where to go?)
