the server does not respond to the request on the broadcast IP
That means it's not a router configuration issue. Furthermore, he's provided zero information on how the router and server are connected / supposed to see each other. If the server isn't seeing broadcasts from the router, that's an issue with either the server or the network. We have insufficient information to determine which or offer a solution.
Has anyone experienced issues configuring Cisco routers via their default config directive
No, I haven't. But "I know what I'm doing". I know how my network is setup. I know how my server is setup. I know how my software is configured. And I know how to troubleshoot all of the parts -- and I'm perfectly happy helping others to do the same. The original question has no information to assist in even guessing what might be wrong.
(I've been to this rodeo. Helping a friend setup a system to reset Cisco phones. A week of back-and-forth by email ends with me driving out to his office to find the problem was something I had twice asked and "confirmed" wasn't the problem -- laptop has multiple network interfaces and the software is listening on the wrong one! I.e. not. a. network. engineering. problem.)
