zero messages in the NAS box, I know that most likely means its the Exchange
servers problem but I'm finding it very hard to get any info from people who
have a similar setup so thought I'd try the storage group.

The Exch feature pack came out at about the same time as iSCSI's popularity
began to increase. They cover very similar scenarios so a lot of folks went
that direction (incl. MS for later releases of Storage Server).

A few ideas to try/check:

1) If there is a switch or router between the Exch. server(s) & NAS box(es)
they can sometimes terminate the link causing this problem.

2) Use perfmon to check for dropped packets, bad links, etc.

3) If you want to try an iSCSI solution, you can get the iSCSI initiator for
free from MS & an iSCSI target for the NAS box from a number of vendors.
