Hi,

I'm absolutely sure that the server is the problem. The application
works a few weeks on different clients xp and nt4. It doesn't change
anything from which client I try to register an event.

There isn't any firewall. Not on the client. Not on the server. All
ports should be open.

Ack, but I don't know why....

If you are familiar with Linux I can give you access to the server.
You can look and try yourself. As soon as a client tries to register
an event the server locks. Everytime.

Besides: The problem occurs after I changed something with the
configuration of the server. But everything else works. And I tried
to take the changes back. That doesn't help.
