What's the role of QoS if everything works (better)

AFAIK it it intended to be used in multicomputer networks ( corporate
style) where there is a QoS management is in place on the network and where
bandwidth management is necessary to guarantee minimum standards for
audio/video transmission.

Small networks, home systems generally work better with no bandwidth
management(or at least when it screws up the way it does in many cases).

Regardless though there seems to be a flaw in the process/strategy.

OK. I understand now that I was wrong when I thought that
QoS was necessary for netmeeting under xp1. I tried to
disable the QoS RSVP service but the connections were still
linked to QoS Packet scheduler, so I think that the problem
came from the fact that the connection was looking for QoS
while QoS could not start. The right way is not to disable
QoS but to break the link between the connection and QoS.

Thanks for your help, you was right when you told me about
QoS and right again when you told me about the link and not
the service itself.

Sorry for entering this conversation late and as a novice, but I got a pointer from someone who thought my recent problems on my laptop after installing an SP2 update might be related to this email stream. I've read through the email here and see enough similarities that it seems like it is worth asking about my specific case.

After installing SP2 (through a corporate interface from an IT group that I generally trust and am pleased with), I started seeing two related misbehaviors that are particularly annoying. After a NetMeeting session was ended, my machine would sometimes change behavior in two programs, Explorer and Internet Explorer. I noticed the problem first in IE where clicking a hyperlink would be followed by about 5-10 seconds of inactivity in that window (the hourglass at the locatoin of the mouse cursor was the only clue that the window was still alive), and only then, after this delay, would there be the usual audible click, the 4-color MS flag in the upper right corner would start waving, and IE would jump to the selected URL.

This slow IE behavior felt like the old days with 300-baud modems, but it clearly was not downloading but rather doing something (or waiting for something) on my own machine, not on information from the internet.

Then I realized that Explorer was suffering from similar behavior!!! A double-click (select & open) on a folder in an Explorer window would also wait for 5-10 seconds before switching folders! This is a major problem to doing any sort of real work, and even though the internet is not involved, the misbehavior appears identical. My guess is that both Explorer and IE are calling the same service which is the core cause. Perhaps this is the QoS RSVP service I have seen mentioned in this email stream? If it is, I don't see how to "unlink" it from NetMeeting, based on these emails. Also, I have occasionally seen the same misbehavior caused by a backup service I use which connects across the network, and I suspect this is also related, given that the resulting misbehavior is the same.

The same engineer who pointed me to this email stream also suggested that I might try Disabling the 'Terminus Agent' (from ComputerManagement:Services&Applications->Services->TerminusAgent->Properties:LogOnTAB). I did this just yesterday, and after an initial freeze up of my machine, it appears that it may have helped, however I have sometimes been lucky to go for a day or two without problems. (Probably I should have immediately rebooted after Disabling the agent, especially since I was running NetMeeting when I turned it off?-)

Any suggestions are welcome, especially if they can be expressed at a relatively "novice" level. Thanks!
