could it be a bad cable? try connecting it with a known working cable.<br />
<br />
Also the nic card could be bad.<br />
<br />
Another thing to check is any software firewall issues.<br />
<br />
<br />
Also, what kind of network are you connecting to? a domain, or workgroup. &nbsp;Is it static ip, or dynamic ip?
</div>


<div>
Try ping with the -t option eg ping 102.178.1.2 -t which pings repeatedly until CTRL/C is pressed if there is an intermittent NIC fault you will see occasional &nbsp;glitches
</div>


<div>
Does it disconnect completly? (status light goes out, windows lists it as &quot;disconnected&quot;)? You might also try forcing the speed / duplex to match whatever the switch it's plugged in to is set to. If its a bad cable you may also have some luck forcing the connection speed down to 10 / half.<br />

I have added a new laptop to our network. &nbsp;For some reason, it keeps losing its connection to the network, can't see the server, can't ping internally, etc. &nbsp;It comes back for a minute or so, then disappears again. &nbsp;Any ideas?

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

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
