Disabling Bandwidth Throttling (IIS 6.0)
The following procedure tells how to disable bandwidth throttling for an individual site. The procedure is slightly different if you are overriding global bandwidth throttling. Either task can also be performed by using ADSI or WMI to update the MaxBandwidth metabase property for the site.
Important You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /user:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
To disable bandwidth throttling on an individual site
Bandwidth throttling is not supported for requests that come to a site by means of an IPv6 address. The MaxBandwidth metabase property does not affect IPv6 network traffic.
