InfoPath Dev

I'm integrating InfoPath forms with Sharepont. Pulling from and posting to a SPS list is no problem. When using a data connection to an SQL table I receive a Cannot Access information Across Domains" error.  I can't find a solution to this issue anywhere. Both servers are in the same sub domain (healthcare.uiowa.edu). ...

Thanks. I'll check this out tonignt. I cannot open it at the office as I only have Infopath 2003. I assume this xsn is from 2007.

I'm trying to populate multiple fields by selecting one field from a data base connection. EG: User selects an account # from a drop down list connected to the data base and the selection populates other fields such as account # supervisor, email address, etc. I'm still stuck in Infopath 2003. Any suggestions?
