MSMQ
Windows 2000 (NT 4.0 with its service packs) provides you with MTS, IIS, MSMQ. Microsoft Transaction Server (MTS) provides you with the ability to write services (or packages as they are called) which support transactions by taking part in transactions supported by the Transaction Manager in MTS. MTS allows you to provide object pooling and load balancing. Therefore applications avail great benefit in the way they can be scaled as it would no longer mean that when your applications have to handle a higher load than anticipated it does not necessarily mean scratching your application from start to get that extra push. Rather it would mean putting a few extra processors, a little bit more RAM and may be a few extra processors to get that load balancing and a little bit more business for the Hardware folks.
