A:
Fix this behavior by changing the default namespace of the Server registration.
Please go to the Server Properties (right click on server node -> properties) and change the default namspace from %CACHELIB to e.g. SAMPLES.

002 - Caché Monitor didn't start properly:

Q:
When I launch Caché Monitor, a splash screen is projected, but then nothing else occurs. If I check the process monitor on my XP machine, I see that CacheMonitor.exe is running, but nothing happens and there are no other screens.

A: 
This behavior occurs if you haven't extract the entire zip file from Caché Monitor. Caché Monitor are missing important files and can't start properly.
In the zip file is a folder called "lib" this folder is mssing in your installation folder.

Extract all files and folders from the zip file into you installation folder and start Caché Monitor again.

003 - Communication link failure

Q:

I can't connect to my Caché Server, i always get an "Communication link failure"

 
A:

If you register a new server in Caché Monitor the default Port is 1972. This can be the wrong port!

If you get a "Communication link failure", please check the port first. You can do that by open the "Server properties" dialog:

Here are some Information about the port handling in Caché:

Caché 2007.1 and above chooses the default ports for installation differently from previous releases. The new algorithm is:  If port 1972 is unused, choose it. Otherwise, choose the first available port number equal to or greater than 56773.

Caché 5.2 does it in this way:  Use 1972 or the first available subsequent number.

So you have to enter the right port number of your Caché Server to connect properly
