I'm having an intermittent problem with Betrieve Error 3012.  Sometimes I get it, other times I don't.  I can get it subsequent to a restart or not; or I can get it after the computer has been on for hours, or not.  This is happening on at least two or our Dell desktop computers.
 
This is our set up:
Classis DBA 2004.1
IS Update 5/17/11
Persvasive 11.10.042.000
Dell Server running 2008 R2 Standard
