The answer was to read the release notes,ie:
4.6.8 CDE's Static Dependency on the Network
The Common Desktop Environment (CDE) provides
facilities and features for applications to
communicate in a networked environment. After the
network is configured and enabled, these features
become available each time a new desktop session is
started. After a desktop session has started, the
current session has a static dependency on the state
of the network configuration. Network and system
administrators should be very cautious about dynamic
changes to the network configuration while in a
network aware desktop session.
Prior to making any dynamic network changes, such as
changing the state of your network adapter to off or
changing your primary network address, add the
following entry to the /.dtprofile file:
export DTNONETWORK=true
The system administrator must then log out and back
in as root for the change to take effect. This
change removes the dependency on the state of the
network. Failure to do this may result in a session
hanging after clicking on a CDE icon, such as the
screen lock or Exit icons.
After all network changes are completed, remove the
export DTNONETWORK=true entry from the /.dtprofile
file.

Subject: Re: CDE hangs on boot
We had the same problem, CDE would hang on boot, XDM would work fine.
Some times CDE would work on boot but hang later.
We bought more memory (we had 32Mb) so now we have 180Mb and no problems
with CDE.
Kind Regards
Hans

Usually this is the result of the machine trying to connect to itself by a
name that doesn't match what it used to be. Did you change the hostname?
Or, more importantly, is the old hostname still defined somewhere?

We had the same problem with an alphastation of ours. We had
specified the dns name incorrectly, there was another machine
at the university that had an alias close to ours, straightening
that out fixed the problem.

I have yet to be convinced about CDE; no one has actually
forwarded a reasonable argument for its existence.
What do you think? why CDE
