I don't understand what you mean by "the services don't want to take the 80 port" - when you restart the server the error log should say something like "listening on 0.0.0.0:80" very near the end of startup. Is that line missing, or is the address printed not correct? It's possible that the new config file (config.tcl) specified something different for the listening address (look under the section ns/server/${server}/modules/nssock for an address parameter)
When you try to connect to port 80, does it connect and wait for input (expected) or do you get "connection refused"?
