Hi guys<br />
<br />
We have a virtual fileserver, Windows 2012 R2 which has DFS set up on it for future purposes. Once every few weeks, we run into this issue where nobody is able to access the mapped drives. This morning it happened. If I tried to RDP to the server, an error message would pop up instantly as though the server was unavailable.<br />
<br />
I had to log onto the actual Vcenter server and restart it. After that, everybody was able to access the mapped drives again. <br />
<br />
The server has 4GB of RAM with dual 3.4ghz processors. C drive has 50% free. F drive has 28% free, F drive has 50% free. Both drives have Windows Volume Shadow Copy set up to take snapshots of both drives twice per day. <br />
<br />
I've attached the log files of the past 12 hours to see if anybody can see anything? Is it paging file related? Is it falling off the network and it is DNS related? I have no idea, so any help would be awesome. <br />
<br />
Thanks for helping<br />

Fileserver unavailable! Logs attached.

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Windows Server 2012

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
