Could it be that there are multiple instances of the ZServer Monitor Server trying to run on port 9099 causing this problem? I don't know for sure. The only other thing I would think of is if you have any other WEB server running or any other application that might use administration via a browser on port 8021. I know my Netscape server administration runs on another port but its not even in the 8000 range. Thomas chas wrote:

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,

chas
