Simon is right about name resolution and the CDE; in fact, the CDE won't
even start if you don't have TCP/IP and whatever name resolution (hosts,
DNS) set up correctly. You haven't mentioned if this is a new, recurring,
or old problem. In any case, try this:
Take a look at your network options. Issue a "no -a | pg" on the system.
Of particular interest will be two of the top entries: "thewall"
attribute, and even more significant, your "sb_max" attribute. Thewall is
the total amount of real memory that's dedicated to the communications
subsystem. It has different defaults in AIX v4.3.X and 5.X (you also
haven't mentioned what version of AIX you're running.) This value should
be between 25% - 50% of your real memory. Now look at your "sb_max" value.
It should be *at least* four times the value of the wall, as thewall is
measured in kilobytes, and sb_max is measured in bytes. sb_max stands for
"socket buffer maximum". It tells you how much of thewall value will be
given over to creating socketed connections, which is just how the CDE
connects. Bump your sb_max value up . Way up. Start with ten times the
value of thewall; don't worry, you really can't mess anything up setting
this value. See if that helps. If it doesn't we can explore other options,
but I betcha that'll help you out.

My first thought would be the network.
Try connecting through Telnet - the one with Exceed is better than Windows'
version - and see if it's any better. Telnet usually performs better as it
hasn't got all the graphics to worry about.
The other problem which can hit CDE very badly is name resolution. Try
sticking an entry for your PC's IP address in DNS or /etc/hosts. I'd
usually expect this to be OK, though, once you've actually established a
