Is this information in a knowledge base article that I can reference? I ran
into this but not from Cognos. My preferredLanguage appears to be rfc
compliant (mine is case insensitive string whereas AD2003 uses Unicode
string) but it was causing this same error when doing the adprep.

Basically, I'd like some MS approved and documented way of either renaming
an attribute so there is no conflict or a way to modify an attribute. I'd
like a link so I can reference the knowledge based article in my
documentation.

Thanks.
