Actually have 28 computers but only 14 users rooms hardwired My board max is 4 gb so to upgrade would have to get new MB as well. Am using the command line to edit sql when I go in and try to edit the AC instance I get User does not have permission message when I edit the others with the max memory command no problem. I have tried it with AC running with me logged in and with it not but that souldn't make any difference since I'm working in SQL I can't find a management console for sql is there a snap in u can run
