AVOIDING CREATION OF LOCAL PROFILES

Hello.

I have two computer labs (2nd and 3rd floor) and I am planning to install windows XP. I want all users to be able to log on but i want to avoid the situation of having XP creating a local profile for every user that logs on the PC.

The best case is to have a common profile stored on Win 2000/2003 server and then whoever logs in will use this common profile.

The profile must perform the following actions:

1. Automatically create some mappings to shared folders.
2. Automatically install printers to the local PC. A problem here is how can I configure the profile in order to install only the printers located on the 2nd floor. But I want the same user if he goes to 3rd floor, by logging in to have the 3rd_floor printers automatically installed to the local PC. I suspect that the PCs's IP address must be used in order to program this functionality. If this is true then the problem becomes more complex because I will use DHCP and no static PC address. Thus I have to create different ranges for every floor and configure DHCP settings for every PC.
3. Automaticall execute some software from the start up folder

Could you tell me some resources that I could read in order to sove this problem?

Thank you in advance.
