I've been experiencing problems with my installation of Zope. the installation itself is run on an NT 4.0 server, and I'm having trouble starting the service so that I can use the system from my own workstation. Since you have produced a how-to about installing and upgrading Zope, I thought someone might be able to help. basically, whenever I try to start the service, I get the following windows message: Error 2140: Internal Windows NT error has occurred. This started happening for no apparent reason earlier today, and I am at a loss to explain it. has anyone ever had any experience of such a problem, or do you know someone I can get into contact with regarding the problem. Since there has been rather a lot of work done on the web site since the last backup, I would be reluctant, if at all possible, to reinstall Zope altogether, however any assistance anyone can give me would be greatly appreciated.
