Where could we look for logging information for iSCSI in DSS? If this doesn't sound like a problem with DSS, we'll concentrate on troubleshooting Windows.
This sounds more like the settings onthe windows side isnt working with DSS.
Has anything been changed? what about frame sizes?
It is also advisable for only one MS initiator to connect to a target. Multiples can cause problems.
