I get an error "Unspecified Error" when trying to set up a new business object that points to an access db file. Attached is a print screen of the error. I can use the BO mapper to look at configurations of OLEDB projects, just cannot create a new one. Any ideas?

So, using the same connection string, can you see the fields on the business objects that are already configured?  Also, does the error come immediately back when you try to configure the new business object, or does it timeout and show up after 30 seconds or so?

Well, since my original post my visual studio ide crashed (as it does several times a day). After opening the the project again, it seems to be working. Not sure what was going on.

Yeah, with VS2005, there's not telling... it might have done something to the OLEDB provider that was running in the AppDomain of VS.
