Hi Dennis-

No problem.  From the start menu click run, and type "regedit" without
the quotes.  That'll open up the registry editor app.  On the left hand
side, expand each of the nodes that map to the registry path you
specified below.  When you get to the Parameters node and select it.  If
you see TcpMaxDataRetransmissions in the right hand pane, double click
it in the right hand pane, and a dialog will pop up that will let you
change the value.  If you don't see it there, right click in the right
hand pane, and from the context menu select new->dword value.
Double-click the newly created value to change its value to 10 or
whatever you want it to be.  You'll also need to rename the value by
right-clicking it and selecting rename.  Let me know if that doesn't
help.

Sorry for the delayed response... just landed in LA so I've been
incommunicato most of the day.

'night,
Steve

ps Be careful with regedit; it lets you change whatever you want to
change, and if you change the wrong thing, the system might not like you
very much.

Dear Steve,
Sorry to bother you with these questions, but you are the only
microsoft god I know.
I want to change the timeout interval so putty doesn't timeout
on me so often.

A web page says to change:

===========
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\
Parameters\TcpMaxDataRetransmissions 

and it must be of type DWORD. (See MS Knowledge Base articles 120642 and
314053 for more information.) 

Set the key's value to something like 10. This will cause Windows to try
harder to keep connections alive instead of abandoning them. 
=============

How would I do such a thing?
Thanks,
Dennis
