You can't.

Years ago when I did my first W2K roll out using RIS on a W2K server I had set the 'client computer naming format' to use the LAST 4 digits of the clients MAC address, plus some static text, "STATIC-NNNN". Since then I've changed it a number of times for different reasons. Now I am trying to set it back to what it was but for the life of me cannot figure out how to do it. Everything I read explains how to use the FIRST N number of digits, "STATIC-%4MAC", but I can find no mention of how to use the LAST n number of digits.
I have 30+ clients here, all named using the last digits of their MAC address. I know they were rolled out via RIS and they they were not pre-staged, so I know this worked at some point... Am I dreaming here or can someone explain how to do this?

Hi, does anyone know that bluetooth signal and wireless network signal could communicate with each other or not? For example, I have a wireless router which is used to connected and share an internet to the client. I have one laptop but i don't have a wirless network card. But I have USB bluetooth and correctly install its driver. Is it possible that my laptop could use usb bluetooth to connect to wireless router to access an internet?

This will only work if your wireless router had a BlueTooth interface in it. BlueTooth doesn't work with the normal 802.11anything wireless protocols.

Thank you very much for your comment. But how could I know that my wireless router had a bluetooth interface in it?

I don't know... maybe read the documentation on it??
Perhaps the manufacturers website, listing the product specifications??

Ok, thank you very much for your comment. I will check its feature from its documentation whether its support bluetooth or not.

Hi
I have been asked to monitor what websites employees in my company visit during work hours.
I had a program that I found from The Code Project, but it no longer seems to be working when used on one of the PCs, I need to be able to view the results as a web page.
Can anyone suggest anything that could work?
Cheers

Yeah, just about any Proxy Server will do this, without running code on the users machine. The down side is any access to the Internet would have to go through this proxy server.

Hi all,
I've been told that a single process can only use a single cpu in a multi-processor set up. Is this true?
I have some code which is highly cpu intensive and I want to make sure I use all available resources on a multiprocessor server. If this is true, I'll need to spawn two processes to do this (for a two processor server).
Comments/advice appreciated!
Regards,
Rob Philpott.

Untrue. The operating system - if we're talking about Windows or any UNIX with thread support - will schedule threads on any available processor [*]. If you want to make use of all processors in a machine, you need to make use of multiple threads, but additional processes are not required.
When dividing your processing across multiple threads, remember that you need to protect access to any shared data. Try to minimise the amount of shared data - whenever one thread is accessing it, if you're using locks, any other thread that needs to access it will end up waiting until the lock is released. A task that requires a lot of access to shared data structures probably won't be amenable to parallel processing.
[*] Not quite true. You can constrain the set of processors that a thread can run on by using an affinity mask, but generally it's better to allow the OS to pick any processor. Windows has a whole bunch of heuristics that control which processor a thread will run on and which threads run at any given time - for details see 'Windows Internals, 4th Edition' by Mark Russinovich and David Solomon (MS Press).
Stability. What an interesting concept. -- Chris Maunder

Thanks for this Mike,
Interesting stuff, and this is indeed good news. I didn't much like the idea of creating two processes to use two processors. I need to delve a bit deeper into this area. Apparantly what can also happen (I'm told) is when a single process is shared over two processors, both will only use 50% of their bandwidth serving it, so although the threads are split over two chips, the overall output is the same as just one running at 100%. Odd.
Regards,
Rob Philpott.

What you're describing is a process with a single thread. To get any significant speedup from a 2nd processor/core you need to write multithreaded code. WIthout doing it you'll see a minor 1 or 2% speedup since your app will have hte equivilant of a dedicated core it won't have to share with all the OS background activity.
|
|

Ah, this kind of makes sense. Although the app in question that exhibited the 50% split was multithreaded, I believe it was essentially a single-threaded-apartment model, where I guess the other threads are blocked outside the apartment. As you say, that explains the 50% split perfectly.
Thanks for your help Mike/Dan.

Rob Philpott.

Hello all,
I'm in the middle of setting up a windows 2003 server for asp.net (with vb.net 2003) remote development/deployment.
The problem is that as soon as I install service pack 1 on windows 2003 I can no longer remotely develop asp.net apps with vs.net 2003. I have set-up servers with all the patches except service pack 1 and they work fine but as soon as I install service pack 1 it breaks the remote development of asp.net.
The error I get is that vs.net is "unable to add" files such as the project file (.vbproj) to the remote project.
I have made a screenshot of this error , it is at
http://www.matcmp.ncc.edu/error-after-sp1.jpg
I'm trying to upload via frontpage extensions.
I have double checked the IIS settings and front page extensions are enabled and so is asp and asp.net.
I know that one recommended way is to develop on local instance of IIS and then upload the project but this won't work in my case because this server is for a college class and students have to be able to work from home.
Thanks in advance for any help.
-Steve

Have you tried running the Security Configuration Wizard again? I think I remember somewhere that when SP1 is installed, Windows Firewall blocks all incomming connections until Post SP1 updates are installed from Windows Update. You might want to run the SCW to open up the firewall again.

Yes I tried SCW and it did not help, same error. I also tried installing all the updates, remaking the policy and applying it. Also tried disabling the firewall alltogether, same result.
Some files do get upload and the remote directory does get made but the error still occurs and the project can not be developed on.

You should check an information about key feature of windows 2003 sp1. Try to check windows server 2003 sp1 homepage[^] and look at the evaluation section to check about its key feature.
|
|
|
|
|
I've looked at that page and nothing usefull regarding this problem is there.
Are you referring to any specific "key feature"?
|
|
|
|
|
I have check your error message. Try to check this article[^] and let me know if its solve your problem or not.
|
|
|
|
|
No, the problems described in the above article are not occuring on my server.
