Can't add content with MSSQL

Tried setting it up on two machines w/ MSSQL, PHP 4.3.2, Drupal 4.2.0-rc, Win 2000

I can open up the homepage, view the settings and create accounts, but when I add any content (a story or static page) the CGI errors out. I ran a trace and saw the following query right before it quits.

INSERT INTO node_nid_seq (vapor) VALUES (0)

This of course isn't a valid query. There's a node table, with an nid field, but no node_nid_seq table.

Can anyone offer any suggestions. Was this just overlooked for MSSQL or the PEAR version of things? I understand it's not used as much.

Thanks
