Guys,
I know there many talented admin in AO.
I need help on this one :

I would like to configure the time during an ARP is cached in a windows NT & 2K. I don't know if it is doable thanks to thge registry & how.

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-
Some detail on why I need this info may help guys in the same situation:

I have a private network based on 100/Eth switches.
One VLAN is dedicated for admin. My switches allows to give a queuing priority for a specific VLAN in case of congestion.

My problem is this priority concerns only unicast traffic there fore I may lose broadcast packet with equal chances on every VLANs. I have 2 Mib Browser watching the private net based on Windows 2000 & NT. When a MAC adress is flushed MIB browser PCs sends ARP to the equipment to watch. This ARP may be dropped because on a congestion and a false alarm will shows up. To make sure that will not happen again I'd like to parameter the ARP cache time in order to be less than the Snmp get frequency.

Maybe you have a better idea, it coud help, thanx
