Question : Cannot configure ODBC System DSN on Client

I hope I am posting this question in the right area.

I have a client PC, running Win XP SP1, that gives an ODBC error when launching the database.  I try to go into the Administrative Tools >> ODBC and check the settings for the SQL Driver and when I click on configure, nothing happens.  I cannot remove or add any SQL Driver DSN's, but can configure, add, or remove the Access DSN's.  Is there a fix for this or am I looking at  reinstalling the O.S.?  I thought about replacing the sqlsvr.dll file from another PC that is working correctly.  Any suggestions?  Thanks in advance.

sounds like it's time to re-install MDAC
