text: firewall on windows 2003 server? i have just installed windows 2003 server i cannot ping the server from a client or the exchange server.  i beleieve its to do with windows firewall doing something.  i have update from the interent when it was ok restarted it and now its dead.  i have tried stopping rras service but nothing.  please need professional help or someone with experience with this problem if you need more infor then please ask.  set up 2 servers file and exchange connected via switch gateway... so many variables.  can the servers see each other?  i am sure you have checked the ip and mask?  first suspect i would look at if i were called to fix the problem is dns.  if your clients are getting a dhcp from some other source than the servers then the name servers will have no idea what your servers are.  really hard to answer this question without more information.
