>>>I created an installation that included setting up some ODBC Connections. However, it now destroys all ODBC connectivity on any machine that it is installed on. This includes connectivity using the Enterprise Manager for SQL Server. Uninstalling, reinstalling drivers, etc. do not bring connectivity back.

>>>Any ideas on what can be done to recover these machines. I can take all of the ODBC stuff out of the installation and we can do that manually, but we need to get these machines up and running as well.

If it doesn't resolve problem with Enterprise Manager try to reinstall MS SQL client side toools.
