My companiy executives dont understand how important Network infractruture really is . I have a awful time trying to convience them to upgrade anything in my network . Everytime I get something they make me try to reuse the old servers some way some how . They made me use a P2 400 MHZ as a domain controller a DNS and a WINS server . this make me so frustrated when they tell me things are slow .What Im asking for is help with key points i can say why I should not place services on old machines . They want me to re use a old P2 server 400 MHZ to host DNS, DHCP, WINS is this bad and why is it bad ?also I have a good server Dual 2.4 xeon Processor but they want Exchange , DNS and to be a domain Controller can you guys tell me what are some key points i can say to suggest this is a bad Idea .
