There is at least MS Exchange running on the server as well. Where do I check what other pluggins are installed?
To check which plugins are installed (and possibly uninstall them), go to Control Panel → Add/Remove Programs → avast! Server Edition → Change/Remove → Change.
Placing a red X next to a feature uninstalls it.
Anyhow I would say there is no information in the license key.
What do you mean, no information? Like in information about Exchange or just no info at all?? 
Sure, you can mail me the file but what exactly would you like me to do with it? If you have the Exchange etc. plugins installed but there’s no license for them in the file then there’s no wonder that it behaves how it behaves…
Thanks
