Are you trying to use this 'ipaddress' field as a key field? If so, you
must NOT check the Treat unknown datatypes as LongVarChar. The reason is
Access can't have a unique index on a field that is over 255 characters,
which is the default max length for a longvarchar.

Try unchecking the option, then you *must* re-link the table in Access to
see if it worked. Also, Make sure the size for "Max Varchar" is set to
the default of 254.
