I'm experiencing a very unusual problem with one of our old SQL 2000 installs. Backstory: we've used xpsmtp80.dll on all of our SQL 2000 SQL Agent jobs in the past, with much success. If certain steps in a job ever fail, the agent jumps to a step in the job which uses xp_smtp_sendmail to notify the proper individuals. On one of our remaining SQL 2000 systems, we started receving email alerts that the tlog backup job failed, although there was no failure anywhere in the job. Fast forward a couple weeks, and we have completely deleted the job in question, deleted the extended procedure from SQL, deleted the .dll from the file system, and rebooted the sever. We are still getting these emails exactly when the old job used to run (we do have a new tlog back job that runs at slightly different times and does not use xp_smtp_sendmail).
Has anyone seen anything like this before? Is there something in the msdb db that needs to be cleaned up? I'm not sure where to go from here. Thanks in advance.
