Someone else this up on the list a few days ago too and we would like to 
get to the bottom of this issue. The ZIP provider is checking that it 
has read access to the zip or JAR file and this requires determines the 
effective access to the file. Determining the effective access several 
calls into Windows to read the ACL and get the effective access and we 
seem to have a problem there. We haven't been able to duplicate it and 
maybe you can tell us a bit more about the environment to help us. The 
main thing to know is whether this machine is in a domain or not? One 
possibility is that when you put the machine to sleep it shuts down the 
network and that disrupts the connection to the domain controller. You 
also mention that the problem disappears if you leave the machine alone, 
I would be interested to know if attempt to access a share on the 
network then will the issue "correct itself" quicker (which would be an 
indication that it's re-connecting to the domain server).
