DescriptionThe following message displays while navigating in the Administration UI.
"HTTP Status 401 - You do not have permission to access the requested resource"
This
has been seen when a Windows machine used to access the Administration
UI has two active network interfaces at the same time (such as both
wired and wireless interfaces are up).
Tomcat-Admin logs will show something similar to the following:
**WARNING** IP Address x.x.x.x attempting to hijack session from x.x.x.x
Windows
can change its active interface periodically. Traffic originally
sourced from one interface starts transmitting out the other. This
changes the source IP address and can trigger Tomcat-Admin to report a
conflict.
SolutionDisable one of the network interfaces on the Windows machine.
