Hi
Can anyone please help?! : )
I am working with a Win2000 IP network over a HF radio system with high
latencies (ping = 35 secs). Putting the jokes aside of 'why bother'!, we
occasionally get a TCP timeout occurring. I know this is because the reply
takes longer than the TcpTimeout setting. The MS info on this is at
http://www.microsoft.com/resources/...s/2000/server/reskit/en-us/regentry/58802.asp
I have changed the TcpInitialRtt value in the registry but this is an
initial value to start the Smoothed RTT (SRTT) which is then dynamically set
using a given formula as discussed in
http://www.informit.com/articles/article.asp?p=130716&seqNum=4&rl=1
SRTT is calculated by values such as [alp], [beta]. Round Trip Timeout (RTO)
is then calculated from SRTT and also has values such as upper and lower
bounds (UBOUND, LBOUND). I have done a lot of searching and can find lots of
information on what I have discussed above, but nothing about where I can set
the values above, particularly LBOUND. I assume these are set in the registry.
