[omniORB] DHCP problem??

[Libor Chocholaty]

Hi,

there are some ideas to find the problem.
As I know, these kind of problems originates in inconsistency in between 
IP address and hostname of machine. If application uses gethostbyname() 
it will be able to get wrong IP and creation of IOR can give unusable 
result.
