That sounds like either the NIC went offline, or more likely the switch or port failed.

Hi, <br />
<br />
In our company, some clients are disconnected from the network suddenly no access to resource ( internet, file server...). But some other clients have access. <br />
<br />
Some users said, after a micro cut they &nbsp;got the connection back. <br />
<br />
I restarted switches, domain controllers, and also the client. i flush dns from the client. But in vain. when i ping to the server from the client which dont have network access, it says ping tranmit failed general failure. <br />
<br />
But in some client we access all the ressources. <br />
<br />
Much appreciated any quick helps .

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
