Recently I deployed a new NAS with Dell PowerEdge 2950. My NAS is running Windows Storage Server R2 and my AD server is still running Windows 2000. My problem is users are suddenly losing connection and are unable to access the NAS. The event viewer shows event ID 1030 and 1058. The only solution right now is to reboot the NAS. Do you have any idea why this is happening and does it have anything to do with my NAS being 64-bit and my AD being 32-bit? Thanks.
