FAQ - Frequently Asked Questions

  • I cannot access the required pages.

    • Do other internet sites work normal?
      First try to login again. If this does not work, refresh the page (keyboard function F5) or via browser. If this still does not work, it could be that your company is using a "MS ProxyServer". It is recommend to explain the problem to your IT-department first.
      For any further questions they can contact our Servicedesk servicedesk@dirkzwager.com or tel. +31 (0)10 59 31 603.


  • I have problems with the webpages (i.e. unable to open the overviews).

    • What type of internet browser you are using?
