Liu,
Thanks for chiming in on the subject. You write neat/nice/cool stuff.

From your profile:
"Though educated as a mathematician with a penchant for complex analysis ..."
Small world, in my "previous" life, I published several research papers in complex analysis and got a Ph.D. in this area.

Well, it's great to meet another member of that select fraternity of advanced mathematics! Luckily, I have the opportunity to work with a brilliant guy at one of the local universities who has come up with a conformal camera based on FFT and convolutions which, ultimately, finds its way into the complex plane. Fun, fun, fun, fun, fun.
And, thank you for the compliment.

Hi,
I have created a user account on my collegues system and i want to log on to his system using that specific user name. However when i right '\\<collegues system="" name="">' in the RUN box, it directly opens the shared folders on his system. Please suggest.

Open a command prompt and type:
net use \\<systemname>\ipc$ /user:<useraccount>

So, what's like the barebone basic hardware requirement to setup MSCS? I been reading books/articles. In addition to both machine having to be exact replica, and that all hardware be from HCL (Hardware compatibility list), you also need to buy SCII controller x2 (each node), NIC x2 (each node) and shared disk setsx2, and 4-8GB of RAM!
Just wondering, if I can get by with 1 GB? Or would MSCS simply not run with less than 4GB RAM? Is this a requirement? Or just suggestion? We just need a testing environment.
Thanks.

Basically, in a simple two-node cluster used to achieve high availability (rather than scale-out) each node should have enough hardware capacity to manage the entire load - because, after all, in a situation where one node has failed, the other will be taking the entire load. If 1GB of memory is sufficient for your application I would expect that would be fine.
Bear in mind that Cluster Service is for fail-over support for applications that require a local data store, such as SQL Server or Exchange. In general, only one node can access that data store at a time - be the 'Active' node (Exchange supports an Active/Active mode on a two-node cluster but few people recommend it). If you just want to scale out an application, look into Network Load Balancing rather than clustering.
The reasons for the hardware: the shared disk set is used so that both nodes can get access to the shared data - it wouldn't be much use if the data (e.g. SQL database) was stored on the local hard disks of one of the nodes, and that node failed. One disk is used as the 'quorum disk' which is used to store shared cluster state - it is recommended that this is an entirely separate disk. The additional SCSI controller is used to access a shared SCSI disk array, although you can use more expensive options such as a SAN using FibreChannel, and I believe iSCSI (SCSI commands over an IP link) is now supported. For any large scale Windows deployment it's recommended that you use SCSI for the local disks too.
Each node should normally have a private network adapter, for communicating with the other node(s) in the cluster, as well as a public network adapter for serving clients.
That's what I've picked up from a little reading on the subject and playing with a cluster of virtual machines using Virtual Server. Here's[^] a guide from sql-server-performance.com, and here's[^] the one I followed, from Microsoft's TechNet site.

Hi
can anyone suggest me some sites for pSOS tutorial.
I'll be highly greatful to ur help.
thanks.

Are you talking about Provably Secure Operating System[^]? It's amazing what a little Google search will come up with.

I'm pretty sure he's talking about Wind River's pSOS(ystem)[^].
I don't know any more about it than that it exists, though.

Hi, I plan to use mobile bluetooth headset. Does the bluetooth signal could affect my health or not?

You'd get more radiation standing next to your microwave or a fuse/breaker box.
Can I ask what your obsession with the affects of EM radiation is all about? I've never seen so many questions about it come out of one person.

I plan to use bluetooth headset and microphone for chatting with yahoo messenger. Because i heard that the signal of mobil phone could affect humn health. So I'm afraid that all signal such as bluetooth could affect the human health too.

you know, the air is full of radio, TV electromagnetical waves...
mobile phones signal *could* affect human helth, but hey, that's still not proved, and even if it was true, BlueTooth don't use the same frequencies as the phones....

What I meant by that is you're the only person I've ever come acrossed that seems to be so worried about the affects of EM radiation from a device. We're constantly bombarded by it from all kinds of sources, in all frequency ranges and by various levels of power.
The dinosaurs got cancer too, and it's a pretty safe bet that it wasn't from a cell phone!
