I just encountered this today and tried everything suggested in the forums with no luck, even after a reboot. After opening a call w/IBM it's now resolved.
As root:
Code:
# lssrc -s portmap
Subsystem Group PID Status
portmap portmap 192616 active
Portmap MUST be active for CDE to work correctly.
Code:
#ps -ef|grep dtlogin
root 290992 1 0 10:52:34 - 0:00 /usr/dt/bin/dtlogin
#kill -9 dtlogin PID
#/etc/rc.dt
Starting AIX Windows Desktop..............
#ps -ef|grep dtlogin
root 323718 1 0 10:56:05 - 0:00 /usr/dt/bin/dtlogin -daemon
You also have to make sure no rootvg file systems are maxed out on space. In our case a users /home was at 94% which can also cause this error.
Hope this helps!
