I'd definitely have him break the storage group into maybe 2-3 storage groups, 
and have each of the storage group broken into 3-4 stores. This should help 
isolate the problem. Also, have him upgrade to 5.1, I know it fixed a number of 
smaller issues we had.

Matthew;

I will forward your comments to the guy who administers this Exchange  
server so he can respond. I don't know much about it, but I do no, its  
just one storage group and the a/v software is the current version of  
Symantec for which we have a sight license.
