Hi Frank,
The webpage you mentioned is rather old, which is why some of the links on there do not work anymore (several parts of our website have been updated since). Therefore, I advise you to use our newest 'wat zit er in?' webpage instead:
http://www.bhic.nl/onderzoeken/wat-zit-er-in
As you will probably have noticed, this newest 'wat zit er in?' overview does not mention the prison registries or the army registries. Luckily, they are still part of our website, as Helena and Maurice have already shown you. You can use Maurice's instructions to go directly to a search engine, via which you can search your way through both registries. Via these hyperlinks you can find them as you previously could; completely scanned but not accessible via keyword search:

I hope this will help you to continue your research!
