Well you have to make an ip address plan, that accomandates the stated number of users and a little more. Also think about redundant paths in your network, to make sure, if one node fails, the lan is still reachable, or funtioning. I would say there is no general answer here. I would just note all teh requirements, that try to find for every point an answer and than combine them to one idea.

Since I'm right now in the company, and haven't so much time, as the task requires, I would recommend you, to try to find some examples on the net. Also, if you have access to Cisco Websites and material, check it. I have passed the CCNA and such questions are covered in the course. But I have no idea about Net Ware.

If you are interested, I could discuss with you, your ideas to that particular question Wopuld be interesting, Iw ould say.

The second questions seems to aim on the basic user adding and changing. I mean, you have to think about creating new groups, new uiserids, passwords and such things. Here I would try to review all the aspects related to the topic. I have not really much experience with Windows 2003. But this question seems to be trying to ask you for a new user policy. The main problem I see, is that you have to make sure, that UNIX and Windows2003 support each other.

Anyway, teaching yourself all such things really helps to get better. It asumes much time and so on, but it's well worth!
