Is your machine on a wireless network?<br />
Wireless is still extremely unreliable for things like this.<br />
The other thing would be to check your network cable if you're not on wireless.

Hi, what was the time period between adding this device and removing one of the Domain Controllers?<br />
Is it somehow possible to disconnect this device from domain and add it back again?

We have something called a DocSend. &nbsp;It is a computer hooked up to a copier that runs an application from EFI that lets you scan a document on the copier and email it to yourself or someone else. &nbsp;At first it worked fine. &nbsp;Now we sometimes not all the time get authentication errors. &nbsp;The software just tells us it is unable to authenticate. &nbsp;The software is trying to authenticate against our active directory. &nbsp;We started having trouble after we removed one of the 2 domain controllers and added a different one. &nbsp;I have been checking the event logs but can't find anything that looks like it would be caused by the docsend error. &nbsp;<br />

Does anyone have an idea on what would cause intermitent authentication errors?<br />

Unable to authenticate

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers. It includes identity management and protection systems, and discontinued systems for threat management and network protection, along with protection for Sharepoint and Exchange. The scope of discussions includes forward and reverse proxy, application and service publishing, virtual private networks (VPNs), outbound access rules, SSL certificates and network routing within either a single node or an highly-available array pairing.
