Title: Replies to messages very slow I have an ExchangeServer5.5 SP3 on NT4.0 SP6. I have a Checkpoint firewall between my users and the DMZ where the Exchange server resides. I have configured static ports for DS and IS to accomodate the firewall and this has been configured as such for several months.For sometime now some of my Outlook clients (both 97 and 2000) complain that replying to emails is sporadically very slow. Sometimes Outlook appears hung for upto 2 minutes. Using a packet sniffer on my firewall I can see the RPC conversation go fine, but when the workstation starts communicating to the statically assigned DS port somewhere along the way the DS stops responding. After several retransmits from Outlook, it gives up and starts the whole conversation over starting with the RPC call. Network traffic doesnt seem to be the issue as in the same period of time my Exchange server answers to other calls. Where should I look for the problem. Any help would be appreciated.

RE: Replies to messages very slow
Yes I have seen these articles and my configuration follows Microsofts guidelines. I do at the moment have netbios ports open but I don't know if that is necessary. However to make my problem clear, my firewall is not blocking anything and doesn't appear to be the problem.The vast majority of the times, everything works fine but in sporadic instances the DS stops reponding to the clients and so the client needs to start the conversation over. As far as I can see this is always after the RPC directs the clients to use the appropriate port for the DS. List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
