Very often, because I've disconnected from VPN or connected to VPN.. a mounted shared volume will no longer be accessible.. the 10.4 system will often hang for quite a few seconds (almost a minute) while it tries to resolve the share... eventually, the system gives me the option to disconnect the share.. and then after that the system is OK.... is there anyway to speed up the amount of time it takes for a network share to timeout so that it minimizes the hang time ?
