[Zope] Errors adding second Zope instance to NT box : asyncore.py error anyone ? error anyone ?

[chas]

This is an error that has plagued me for weeks/months whenever
trying to add a second Zope instance to my NT box. The following
error messages always appear when I try to run start.bat for the
second instance (even if the first instance is not running) and 
the second Zope instance never starts.

Does anyone have any idea what's causing it ?

Again, I stress that no other Zope instances were running when the
above occured. 

The steps to repeat this.
I already have one Zope server installed on my NT workstation box.
With this Zope instance NOT running, I then do the following :

1. Install a second Zope instance in its own separate location
2. Copy over the Data.fs from the first instance, and the extensions
   directory and the products from /lib/Python/Products
3. Try to start the second instance. No joy :(


Thanks in advance,
