I've checked the event logs on the XP machine, and there were no errors, and even no informational entries that seemed related to the attempts to access the Vista computer. The idea of trying to access the Vista SP1 computer from another Vista computer not running SP1 is a good one, but since all of my Vista computers have now been upgraded, it would be difficult to perform that test. I did look carefully at permissions, and the folders of concern on the Vista SP1 machine provide Everyone with Full Control on those folders, so I wouldn't expect that to be the issue. I've also checked the File and Printer sharing ports on both the XP and Vista computers and they match and are enabled through the firewalls. I'm still stumped.
