I downloaded that from the USAC (people that manage USF, E-Rate, etc.) web site. I've tried many combinations of importing to Access, linking ArcCatalog to Access, ensuring headers don't start with a number, changing spaces to underscores in headers, etc. I always end up with:
Start Time: Wed Feb 11 12:32:14 2015 ERROR 999999: Error executing function. Failed to execute (TableToTable). Failed at Wed Feb 11 12:32:14 2015 (Elapsed Time: 0.00 seconds)
I read a few posts on different sites about the issue, but it was always with people using their own Python scripts. I'm just using the standard ArcCatalog import function.
