time out error

hey, I’m trying to connent one of the navision clients to the server but i’m getting this kind of error ‘‘There was a time out in an attempt to establish acoonection with the server(TCP/IT error ETIMEDOUT’’. I have contacted the network admin. but he says no problem with the network settings. Any idea on how to solved this.

What version ? what are you entering as the service name when connecting ? Can you ping that service name you are entering ? Is that problem existing at a certain machine only ?
