CRM does not sync with Exchange and toolbar(plugin) does not work

When using:
Outlook 2003 SP2 and Exchange Server SP2 with CRM 3.0 and the CRM
Plugin, the problem is that:
the buttons in the toolbar do not work either directly after install or
at least after some time. Items of CRM and Exchange seem to be not
synchronized (anymore)

* The creditionals including password are saved in IE so that when you
connect using IE there is no prompt for creditionals
* The Server is added to the proxy-exclude-list and the trusted
websites
* The Server is correctly registered on our DNS and i even added the
its entry in the windows\system32\drivers\etc\hosts-file
* There are two gateways(no nat) in between the client- and the
server-machine

I have also tried:
http://crm.ittoolbox.com/groups/technical-functional/ms-crm-l/troubles-usingsyncing-activities-in-both-outlook-crm-808423
but it already failed in the first place when trying to register the
dll.

* The repair-function mostly either does not work(because not
displayed) or it does not change something
* Even when installing the plugin and putting the ip-adress of the
server the problem remains/re-appears

I am graceful for any other hints.

I even tried to:
* Give the user a new profile and reinstall the plugin on that new
profile => everything seemed to work perfectly but after the first
reboot not anymore
