HP-UX Desktop Troubleshooting Guide

“The specified XDM host is unwilling to manage”
This message is commonly encountered when there is a configuration problem.
The configuration problem is generally with files such as Xconfig file, Xaccess
file, and so on.
— Xconfig Configuration
The Xconfig file is either located at /etc/dt/config/ or
/usr/dt/config/.
Xconfig will have a reference to the Xaccess file. Check the Xconfig file in
the /etc/dt/config directory first, and then check in the /usr/dt/config
file.
The reference must be: Dtlogin.accessFile: Xaccess
# #########################################################################
# Note: If you do not specify a full path beginning with a "/"
# dtlogin will first search for the following files in
# /etc/dt/config then in /usr/dt/config.
#
# #########################################################################
Dtlogin.accessFile: Xaccess
