Generally, I try to solve the cause of this behavior as it's normally related
to an upstream network issue.
If you can't solve it, then adjusting the underlying TCP/IP stack to be more
error-tolerant may be your only issue.
Why do you not believe that MTU adjustments are inappropriate?
What is your Internet connection?

Thanks Jim, I also found this last night, just was a little afraid that it
would slow down the machines. There was some discussion regarding forcing
the MTU size under 1500 but I vetoed that thinking that should not be a
problem anymore, and would cause more congestion. I put this in place on
one of the servers in the array this morning (the TCPInitialRtt=5000) and we
will see how it pans out.
Thanks for the confirmation and I will let you know what I see. BTW, have
you used this before?
Thanks -- Carl

I'm having some issues with TCP packet retransmits. I have checked the
switch, and everything along the way. What I'm wondering is since the
Source is always the ISA servers, if there is a retransmit value I can set
either on Win2k or on the card (Intel Server cards) that would increase the
value of the timeouts.
Any help would be appreciated.
Thanks -- Carl
