Has /etc/hosts the lines for localhost 127.0.0.1?
Some other tips:
Copy the /usr/dt/config/Xservers file to the /etc/dt/config/ directory: cp /usr/dt/config/Xservers /etc/dt/config/Xservers
Edit the /etc/dt/config/Xservers file to turn off access control by adding a '-ac' option to the last line of this file:
* Local local@console /usr/bin/X11/X :0 -ac
cp /usr/dt/config/Xconfig /etc/dt/config/Xconfig
Uncomment the following line in the /etc/dt/config/Xconfig file:
Dtlogin*authorize: False
Re-load the X server:
/usr/dt/bin/dtconfig -reset
