What does QoS do and is it necessary?

The event log contains this warning: This host can not be ACS since the Active Directory has not been properly configured via the QoS ACS management console. Please configure the subnets via the QoS ACS management console.

This machine is a 2000 server that is only used for some older student applications. Our PDC is a 2008 server and our SDC is a 2003 server.

The other Event Warning is:
QoS RSVP has failed to find any interfaces with traffic control enabled. Install QoS traffic control services via network and dial-up connections.

Can I just uninstall the QoS Admission Control Service on this machine or is it still being used in some way?

Most answers I've seen on this issue I think assume that the server has more functions or has more of a role in the domain...

thank you for your help...

QoS is quality of service . . . it enables packet scheduling to ensure priority packets can have the bandwidth it needs.

Example: If you're on a phone call via Voice over IP and someone starts downloading a huge file, they can actually disconnect the call because no packets could get through to you. By configuring QOS, you could say that phone traffic always takes precedence over file traffic.

As long as your applicaitons don't have a priority QOS can come out.

I would imagine you could disable the Qos, as it is unlikely the applications are qos aware. For that matter it is unlikely that the network is qos aware....

As indicated in my first post, this 2000 "server" has one purpose and that is to run an old Windows student classwork application. It does nothing else but host that applicaiton's data files that the students and teachers access.

Are you saying that given that, I can uninstall QoS Admission Control Service?

I found the QoS Admission Control panel but wasn't sure what the reference was to ACS ..."This host can not be ACS since the Active Directory has not been properly configured via the QoS ACS management console. Please configure the subnets via the QoS ACS management console."

Thank you, I removed QoS Admission Control Service and we'll see if that helps. (I realize they were just warnings, but those crazy warnings always get my attention...)

Many thanks
