The EX4 has updated itself to 1.04.04.
That quite likely has nothing to do with what has happened, since my Seagate Business NAS has also disappeared.
I run Windows 7 Ultimate on several workstations, and have two Domain Controllers running Win Server 2008 R2. All computers are fully updated.
Everything has been running smoothly with access from any computer until two days ago, when both NAS objects disappeared. I can tracert both, but I cannot even map either of them. Nothing has been done with either DC or any Windows 7 machine. Consequently, I am at a total loss in explaining what is going on, but suspect its a DC setting. Cannot find any errors with the DNS, or Active Directory settings.
Has anyone else come across this disaster?
