Hi Mr. mp527,

We get this at some sites. Its more frequent where they run
ActiveDirectory. Its more frequent where they have more users. Its
more frequent where they use PCAnywhere. Thats all we can say at
present. I have been wondering if its just IB/FB doing garbage
collection and making the database unavailable to others... causing
Windows to lose its mapping/sharing - which it is a master at doing. I
am still trying to think of suitable tests to prove/disprove this
theory. The best solution would be to put it on a Linux box. :-)
