If the other computer win XP pro, you can edit the policy of the computer under hardware settings (have not done it in a while), you will have a section called QOS (Quality of Service) you can limit the amount of bandwidth that system uses (in percentage) I have found that this works quite nicely. I don't remember the exact place to look for it, but it's no good to you if you are not using XP Pro. Let me know, and I will be able to help you out better.
Normal ICS doesn't support bandwidth limiting, JJB is correct about that, the above mention tip about QoS would only be if you are running QoS services and such and I do not believe it works to limit 2 comps connected together.
QoS is running by default in all versions of XP, and will actually hog whatever percentage of bandwidth you have it set for. The default is 10%. It could actually be used for the purpose at hand. Not the best, but it would be a workarround.
Quality of Service Defined
Quality of Service is an industry-wide movement that achieves more efficient use out of network resources by differentiating between subsets of data. The IETF (Internet Engineering Task Force) has played a central role in ensuring that QOS standards enable all affected network devices to participate in the end-to-end QOS-enabled connection.
Quality of Service provides applications (or network administrators) with a means by which network resources — such as available bandwidth and latency — can be predicted and managed on both local computers and devices throughout the network.
With such an all-network encompassing definition, QOS functionality requires cooperation among end nodes, switches, routers, and wide area network (WAN) links through which data must pass. Without some level of cooperation among those network devices, the quality of data transmission services can break down. In other words, if each such network device is left to make its own decisions about transmitting data, it would likely treat all data equally, and thus provide service on a first come–first served basis. Although this may be satisfactory in network devices or transmission media that are not heavily loaded, when congestion occurs, such service can delay all data. With this information, we can extend the definition of quality of service — it allows preferential treatment for certain subsets of data as they traverse any QOS-enabled part of (or devices in) the network.
Microsoft® Windows 2000® implements quality of service by including a number of components that can cooperate with (or invoke) one another. These components are found in DLLs, protocols, services, and individual network device functionality.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
