I have been using IIS4 for 6-9 months and so I walked the exam with 890.
Word of warning when it comes to the simulations is to check that the service is running again after you have completed the exercise.
A question on WINS servers came up which is not on the list of things to learn.
I would say that 50 of the 55 questions that came up have been mentioned already on this site. Thanks to all those who submitted them.
Microsoft says that it is pos. to down load a simulation test but I can not find it any where. Maybe its on the MCP private site.
All the best
