Hi It's not so, that I didn't already try to tweak my system. In fact I was obliged to apply DrTCP, otherwise I wouldn't be able to see in the internet explorer some sites. The reason why I ask is simply to know if other people in this list use a different way of finding out what size to use for all the parameters, which can be applied in DrTCP (or in another application). In my network I've got a server which is connected to DSL and to a HUB. All the other PCs are connected to the HUB. My server is not tweaked at all (and I don't know if this is necessary). The other PCs were tweaked with DrTCP. For some reasons, my PC reacts as if it became "tired" (some times it takes quite a time (up to 5 sec.) until the first the picture of www.google.com <http://www.google.com/> is fully shown on the screen). Is there maybe another way of finding out the different sizes of MTU, TTL, TCP Receive Windows, etc.? A way which is really "strait forward" and easy. I'd appreciate any answer which will bring me closer to my goal. Many thanks in advance Oded ----- To unsubscribe, send a message to win2kforum-request@xxxxxxxxxxxxx and put "unsubscribe" in the subject of the message.
