I have a server installed on my client site and that server has only one workstation... how can I find if the client has connected any other device to the server? for example: if I want to check this every week to make sure only my workstation was connected and no other devices were connected?

|
|
Any computer or device connected to the network? Or some device plugged directly into the servers USB ports? Or what?
You have to be more specific.
|
|
|
|

I only have one computer or sometimes (max) of two computers connected to my server.. so mySERVER and computerA and computerB
what I want if any external devices (USB) was plugged in to mySERVER. also if any computer was connected to mySERVER via LAN as no one should connect his computer to this server.

Then you have to physically secure the network and the server. That's something you cannot code.
What good is it going to be to know that something the was connected? You can't determine who did it or why, so I fail to see how it would do you any good...
This stuff cannot be coded as it's all handled by properly configured policies and network controls. If you don't want someone attaching devices to the network, you'll have to limit access to the network in the router.
Again, this is all stuff that cannot be coded in an application.

If the server is using DHCP and you want to limit the clients that can connect (and dont use the word 'client' for the 'customer' its confusing) you can limit it only to the MAC address of your particular client.
If you are talking aboute devices conected to the server then lok at setupoem.inf (in various places depending on windows version). It records the history of devices connected to a machine.

I connect a digital camera.
In windows 7 , Autplay Pops up to ask if it wants to open the media to play the files.
I want to disable this automatically for the applcation I'm writing for the camera. I know it's stored in the Registry.
I need to disable autoplay specific to this device. A system wide Autoplay-stop is working fine, I found where it is configured in registry.
BUT a device-specific autoplay stopper, I'm not able to find  I've tried entering the CLIS id for the device in AutoPlayCancel handlers..Nothing seem to work.
Any help please?

Why not just autoplay a tiny app, whose only function is to immediately close itself?

Its a USB device?

OK, you add a kernel filter driver that modifies the device characteristics structure when the device returns it to the system. I seem to recall you set the device removable flag to false, buts its been a while since I last did this.

That would work, but it means modifying stuff in the System Volume Information directory on the drive, which you won't have access to if you're only writing software to run on the hardware (and possibly on different cameras) -- to do it for all instances of a device, you'll have to get it done during manufacture.
If it's OK to do it for just one device, the System Volume Information directory is made accessible by disabling simple file sharing on the computer, then editing the security of the directory to give yourself rights.
I'll be buggered if I can remember which file to edit (or even if the flag is called "removable"), but Google will tell you what they all do, when you've got in to look at them.

No you dont.
You create a filter driver, intercept the IRP_MJ_DEVICE_CHARACTERISTCS on the way back up for the device and change the value. You then specify the service entry for this new driver in the HKLM\SYS\CCS\ENUM\USB\<your device=""> by adding an UPPERFILTERS REGSZ. The new filter driver then gets loaded above the ordinary USB driver for the device.
All other IRPs are passed down with the IoSkipCurrentIrpStackLocaiton() call. But look at the DDK for an example of a filter driver, and since it is probably buggy, use Oneys book to put it right.

heh.
Give a man a hammer, and every problem is a nail.
Give a man experience in writing drivers, and every problem is solved by writing a driver.
It looks like Bernard got the right answer.

Bernards solution only works when you have your app already running. If you want to disable it completely for a USB device then my solution is the one to use.

Since VuNic wrote: I want to disable this automatically for the applcation I'm writing for the camera.
I assumed that my solution would solve his problem.
But yes, there are some more caveats: it is only the foreground window to receive the QueryCancelAutoplay message. When a common message box pops up from your application, the message will be sent to that window, and the message box doesn't handle it... Of course, there's a solution available here: register for the device arrival message (sent to any window), check vendor id and device id, then pop up your interception window (when I remember correctly, it need not be visible for that purpose).
If you want to disable AutoPlay for a specific device also when the application is not running, your version would be required. But here, I'd prefer to have AutoPlay opening the application.

Yeah but Windows is popping a dialog before he can run any app.
Of course what he COULD do is to put the app, and an autorun.inf on his camera and have it present itself as a USB stick to the system when inserted. The app can then instruct the camera to do whatever it needs to do.

I need to talk to someone who is absolutely familiar with dual boot windows setup.
I mean no offense, but I just cannot go with " try this and see" approach. Been there , done that.
I have two basic disks ( no dynamic) on my secondary IDE. I have Windows 2000 pro( disk manager identifies this as (system)), Windows 2000 server (disk manager identifies this as (Boot) and XP on the third partition of the first (master) drive and Windows 2000 pro ( disk manager identifies this as (Page file))on the second drive ( slave).
I ended up with this setup after win 2000 server basic drive was about to fail ( per bios error) and my Win 2000 server CD would not load. ( Long story) .
I need / want only the server to work.
If I remove the second basic disk from the IDE ( both physically and in bios) - the server will start but I cannot log on (CTRL ALT DEL) and get an error message that there no page file.
All partitions have pagefile.sys on them!
Essentially I need to keep the second drive plugged it to make the server work. I would like to clean this up or use the second drive for real, not as a page drive.
Please be nice and reply only if you can help me get the page file working correctly in my current OS and hardware system! “Upgrading” is not an option!
Thanks for understanding and for your help.
Cheers Vaclav

The fact that you have files called pagefile.sys on various drives doesn't matter if your OS is looking for it in one location and not finding it. What you need to do in order to remove the 2nd drive is to explicitly tell windows that the page file belongs on the first drive. I believe the control panel pagefile settings page allows you to do this if you switch from let windows manage the page file, to let me manage the page file; but it's been far too long since i used win2k to give detailed instructions.

Thanks, but I have not found any "tell windows" options.
Could I do this - remove the page file from the "offending drive" and than add one to where OS wants it?
I have not try that. But I susspect it may not work.
Also , why is page file needed in the first place ( I got 1.5 GB of RAM!) , especially on start up / log on??
PS I did a stupid thing - I moved the IDE's around( first IDE XP second Win2000's) and now I need to find how to do dual boot in XP.
I do not see any boot.ini there.
I'll google it.

Luc, thanks, the article explains a lot.
I wish someone would publish all the stuff which is in registry and how it can be modified.
Why is it kept "secret" is beyond me.
For example I have an extra partition on the OS drive I want to keep so I can put a page file on that. I still do not get why the page file on the Win2000 server is invisible to the OS.
Aslo I cannot delete some of them in OS, I'll need to go to DOS to do that.
I also do not get why I cannot log in if there is no page file available.
That should not stop the OS from working, even if slowly. After all , the page file is just an extra RAM.
Also it seems that if the page file is on USB drive the OS cannot use it.( I did try that and it did not work)But that is no surprise , USB and MS OS do not work that great together anyway.
Thanks for your help.

Because MS hadn't finished writing graceful error handlers for all the fail cases that would never be seen by anyone configuring the OS in the standard fashion.
I'm 95% sure XP and later will gracefully handle a nuked page file.

This could easily be by design in newer OSes; since win2k can't handle a missing page file I'm virtually certain not allowing one to be created on a removable device is by design. USB's overhead/botttlenecking could be too high for acceptable performance in the bulk data transfers that paging involves.

IIRC paging to USB memory sticks was added to XP when netbooks with small/slow hard disks emerged.

Was it? Readyboost in Vista/later would do similar, but I don't recall anything similar for XP; and readyboost was IIRC only intended for smaller data transfers (where latency mattered more than throughput) not bulk data shifts.
