I've setup contact store several times and haven't had any troubles. The system that I'm trying to load contact store doesn't work. When I type in I get an http error 500. this means that the web pages / site isn't setup. I have verified that the services are running. The only difference between this site and others is this computer has XP Service pack 3. The other two site had XP service pack 2. Does any know if contract store will work on XP service pack 3. The knowledge base and ipo matrix don't say.
