Just recently all of our scheduled SQL Agent jobs on a single SQL
server began failing with the following error:

Error: -2147023898 (800703E6); Provider Error: 0 (0) Error
string: Invalid access to memory location. Error source:
Microsoft Data Transformation Services (DTS) Package Help file:
sqldts80.hlp Help context: 713. Process Exit Code 1. The step
failed.

Running the jobs manually does not give us this error, they run just
fine.

Running the same jobs on other servers work, so it appears to be server
specific. Right about when the failures started we had a power outtage,
but the Networks groups say that this SQL server did not go down. It's
possible that a domain controller did though.

Does anyone have any experience troubleshooting this kind of error?
