I disabled ipv6 and changed the MTU from 1500 to 1470 with no success. I installed an openvpn tunnel on the server and encapsulated the ip traffic in udp packets to the clients.no change. I installed a second NIC on the SBS and connected a laptop with a crossover cable directly. The SBS 2008 is connected via a linux firewall to the Internet and firstly a switched over to a D-Link router, but no change. Of the Outlook clients are crashing with a send Bug-Report.
Up to 5 timesĪ day for a maximum of 15 minutes, I am not able to connect to the IIS7 with some clients even for a single http request to a single static html file and 50 percent of the connected Outlook-Clients are showing “Verbindungsversuch” (retry to connect) and some I use only the Exchange part with eight Outlook 2007 clients connected via Outlook-Anywhere and two Blackberrys via BPS. I have installed a SBS 2008 on a new HP M元50 Xenon Quad-Core Server with 6GB RAM.
