Hi David,
You mentioned you had an MSSQL database on your local machine. Is the form configured to connect to SQ? If so, it won't work on another machine unless that machine has SQL, with the same ODBC connections enabled.
If the form does not use SQL at all, it should work fine.
So, I'm guessing you have a SQL-DB backed form and that it won't work unless a) everyone has access to a SQL database that is on a server, or b) you have a Web service that the form calls to query and submit to SQL.
Best of luck,
P
