I have never understood why schools use RM systems and following this and other threads describing the trials and disasters that you have suffered I am at a complete loss to see why anyone uses them at all. Installing and setting up a new curriculum network is a fairly simple process (don't all shout at me at once:D, i have installed over 16 curriculum systems in the last 3 years) the last one was in the February half term 2009. I replaced a clapped out RM school share system with a new windows 2003 active directory server running ranger. the system consisted of a dell t3500 quad xeon terabyte server, 32 levono r400 laptops, 6 wireless N wifi access points, 5 24 port gigabyte network switches, followme network printing ( so easy to do just 2 lines of text in the login script and location variable set on the pc or laptop, no need for pages visual basic. if you want details please drop me a line) migrated all the pupil and staff data. all done in 5 days by myself and 1 colleague for a total cost of £23,000 which included the cost of all equipment and software licences and installation charges. job done and all workin perfectly for return to school on monday morning:D
