Hi Bill,

>When I run a stored procedure that takes parameters and updates a table on my machine here, it works fine.

How large is the content of the email field? I've had problems with memo fields in the past, although I can't recall that error message in this case.

I'd check the SQL client configuration. Maybe there's a difference between your machine and the client's one. If that doesn't work, I'd use the ODBC tracing utility to log all ODBC conversation and a network monitor like Ethereal to log the actual network traffice between the ODBC driver and the SQL server. For the server side I'd use SQL Profiler to find out what actually is received.
