From: RCan on 18 Apr 2010 14:46 Hi Charles, understand - haven't tested this but if you configure the NLB to listen on specific ports (like 80/443) for your websites and leave the DC well known ports unused in the NLB port range. But again, I'm unsure if this will work smoothly and you should test this intensively before you it for business critical apps/sites. AND still unconfirmed if DS is supported on top of NLB ? PS : really no other "good old" 512MB hardware available .... :-) ?

From: Charles on 19 Apr 2010 04:56 Hi Ramazan The NLB will only be using a handful of ports, so it won't be a problem leaving the DC ports alone. This is a test environment, so the right place to be trying it out at least. Unfortunately, the servers I'm doing this on are hosted, rack-mounted, and so any additional hardware would have to be rack-mounted as well, and we'd have to find space in the rack or get another rack. Not straightforward, sadly. Thanks for you help.
