NT Domain users & groups are no longer recognized and authentication fails.

Technote (FAQ)
Problem
Users defined in NT Domain groups used will not authenticate and recently began to fail. Searching for users and groups through the administrative console also failed to find domain users and groups.

Discovered the following messages in the NT's system event log.
ERROR:
The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{F035566B-D87E-4917-9D5B-70F62EECE0EA}. The backup browser is stopping.

WARNING:
The browser was unable to retrieve a list of servers from the browser master \\CAUAT009 on the network \Device\NetBT_Tcpip_{F035566B-D87E-4917-9D5B-70F62EECE0EA}. The data is the error code.
Cause
The server that was acting as a master browser was secured to a point were other servers were unable to pull the server list from it.
Solution
Resolved this by disabling it as a possible master browser candidate and the following election chose a different server as that segments master browser.

Disabling a server from being a master browser can be done by changing the IsMasterDomain setting to false in the Windows server's system registry. See MicroSoft documentation on using Regedit for editing the systems registry.
