Excel ODBC / TNSNAMES issue...

Running Windows 7 SP1 (32-bit), Office 2010, Oracle Client 11g, and two System DSNs that point to Oracle databases.  I can resolve both ODBC conenctions via a command prompt and tnsping, and I can connect to the ODBC connections via TOAD for Oracle.

Where I'm stuck is that when I attempt to connect within Excel / Power Pivot, it returns a TNS listener error.  The issue is user specific as I can switch users and connect via Excel with no issues.  Looking for a user-specific setting, registry setting or even a cache setting that may store this info.
