Bizarre behavior - noticed today an exclamation mark on the LAN icon in the start menu on 2 devices, a Windows XP machine, and a Windows Server 2003 machine. &nbsp;When going into the Local Area Connection Status, it shows the Status as: Authentication failed. &nbsp;These are the only 2 machines i noticed this on today, they still have full network connectivity, and everything seems to be working as normal. &nbsp;They both have Static IP addresses set at the computer/server. &nbsp;Nothing has changed software wise, no driver updates, no installs, etc. It doesn't seem to be happening on any other staticly set computers or servers. No I did not try a restart yet since the server is actually our exchange server. &nbsp;Again no connection issues.<br />
<br />
The only thing recently changed was our switch where these 2 devices connect. &nbsp;I was reading something about 802.1x, but it doesn't seem to affecting any other devices connected to this switch, so dont know if this is on the switch end. Any ideas?<br />
<br />
Thanks!

Authentication failed status in local area connection

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 Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

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.
