DMZ and Ping issue when changing ip address for a server
I have got a media server 2003 installed in DMZ zone (Cisco PIX 525) , with an ip address 192.168.101.204/24, it was able to ping other servers (sql server , help server, etc ) which are in DMZ zone as well. Basically all servers are in DMZ area
Recently this media server is not able to ping these servers (sql server , help server, etc) , I do not why, but if I changed the ip address (last octet only) for this media server to 192.168.101.222 , it would be able to ping other servers (sql server , help server, etc).
There is no firewall on the media server and there is no firewall on the other servers as well.
All servers have got win2003 OS.
The error message for ping is : timed out
This is no entry with our cisco PIX for both IP addresses 192.168.101.204 and 192.168.101.222

Are the servers in the DMZ all connected to the same switch? If so, no need to look at the pix as the possible culprit.
Are other protocols working or is the problem specific to ICMP?
The media server can not ping the other servers but can they ping the media server?
Have you consoled into the switch to look for errors on its part?
Sounds like a beautifully random and illogical problem... if the media server does not require this function I'm thinking its best to slowly walk away keeping sure not make any sudden movements and later contemplating murphys law over a tall cold one.
Good luck to you sir!

I forgot to tell that we have got two cisco switches in dmz zone 3550, and both of them as connected to each other. The servers in MDZ are spreaded between these two switches.
