When you got this error  it is related to managed server configuration it might araised when you newly configured a domain.

This Exception trace tells you what to do. Read the first line carefully, 

<Mar 30, 2009 2:56:49 PM EDT> <Critical> <WebLogicServer> <BEA-000362> <Server failed. Reason: 

There are 1 nested errors:

java.net.UnknownHostException: mywebhostname.com: myhostname.com

        at java.net.InetAddress.getAllByName0(InetAddress.java:1128)

        at java.net.InetAddress.getAllByName0(InetAddress.java:1098)

        at java.net.InetAddress.getAllByName(InetAddress.java:1061)

Hence ping from all web machines before you go for starting managed server first time in a domain to Admin server is running on machine. 

1. There could be DNS names in the routing table which are unresolvable

2. IP address can be accessable when you access with FQDNS it doesnot work means DNS names not resolving at your machine.

3. One more issue there could be when one of the router restrarted in your network, there may be possibility of DNS clash. Such as same name can be assigned to two IP addresses.

Unix command identifies that there is a problem when the managed server connecting the admin server first time the machine is not able to lookup the remote machine where admin server is running.
