Any webīrowser is still waiting for the requested data or an error-code and goes into a timeout after 5 minutes with the message “The Server is not responding”. But when the error occurred, the IIS7 is only responding with an ack package with no data in.

(.png files below)Īfter the syn, ack, syn ack, handshake normally a get yxz.html IP package is send by the browser and the server should respond with a http header IP package. I installed Wireshark on the Server and did a screen capture from the server-side with an include of a tcpdump on a Linux/Firefox client when the error occurred and one capture when not. Access via IE7 and Firefox directly on the Server to /nagios and any other services (rdp smtp.) from external are always working fine. I did set up a simple virtual directory called /nagios to With IE7 and Firefox on Windows and on Linux I got a Browser-Timeout after 5 minutes via any externalĬonnection to the Server (NIC1, NIC2 and TUN device). 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.
