Do you mean that your dedi server cannot "see" the resources defined in description.ext file and hence is not able to handle with tittles or dialogs defined there?
A dedi server doesnt have any player, so any sound or visual resource activated only in the dedi server will not be "seen" by anyone.
If you have a tittle named "mytitle", try the following in the init.sqs file:
;Wait here few seconds
cutRsc ["mytitle", "PLAIN"]
