To be honest I would leave the setting exactly as Microsoft had it. I don't understand why you think this value will give you any performance boost. The amount of time it takes to query the USB host controller can be measured in nanoseconds which is to say billionths of a second. I cannot argue that there will be zero performance gain, but any gain will be infinitesimally small.
Best Wishes,

I am just using my computer for surfing the internet; and I guess the computer circuit is not being swamped with a backlog of data that requires processing
and I also am not running any programs that require alot of processing such as video games or movies that would more quickly utilize all the system resources
that are available in the computer;so every speed tweak is of less significance for my computer ;I suppose.
The ram memory clock speeds are alot slower than the microprocessor speeds.For example,the microprocessor is 1.79 gighz and the ram memory is about 400 mghz as the bios spec says the "system bus speed" is 400 mghz in the computer that I am using.
If I can stream line the xp operating system processing requirements without compromising or undermining any of the other operating system parameters ;
then I prefer to customize it especially if it is a simple setting adjustment.
Whenever I do a re-installing of the xp imcluding formatting; I always notice a general increase in the speed performance of the computer after I have done a few of the xp performance tweaks that I have read about in computer magazines or on the internet.

On second thought, I think that O'reilly was correct when he implied that the "IdleEnable" would register the number in seconds;because when I first did the tweak several weeks ago,I now remember that I checked a few times for flashing usb thumb drives ;by plugging in the thumb drives [on a usb drive hub] after the computer had booted up after I had entered a number value of 20 into the newly created Dword called "IdleEnable".
And the usb thumb drives did not start flashing until about 15 to 20 seconds after I had plugged them into the computer.And I also checked the time a few more times in the following few days with the same result.
But now; I am unable to customize the setting with my own chosen values;as the usb thumb lights seem to automatically start flashing about 3 or 4 seconds after I connect them to the usb drive;whether I try values of;for example of 60 or 60000.
I think I know the reason why.
About a week ago I downloaded the newest bios version[A02] from the Dell internet site and then I decided to uninstall it because of some modifications I did not like that had been done to the xp operating system.
So I downloaded the original bios version [AO1] that my computer had come with.But the Dell techs tell me that the AO1 version that is on the internet had also had an update ,which I could tell because one of the AO2 modifications was on it - "the microsoft management console".
The bios updates are done by the Dell engineers;so the Dell techs tell me.
So I am speculating that the DEll engineers also included a change to the usb drive polling default setting of 1 millisecond and increased it to a value of about 3 or 4 second;and I am unable to change that value by creating the IdleEnable Dword.
I would like to get the original AO1 bios version that does not have the "microsof management console" in it and I would not mind having the option of setting my own usb drive polling value; although the 3 or 4 second value setting is a significant improvement over the 1 millisecond default setting.
But that 3 or 4 second delay does not necessarily mean that that the default setting has been increased to 3 or 4 seconds because there was always a couple of seconds delay when first plugging the usb thumb drives into the usb drives;and this is going back several months ago.
Because of a couple of NEGATIVE REGEDIT DELETES that were done in the regedit of the AO2 bios; I am now SUSPICIOUS that one of the Dell engineers has now REMOVED THE OPTION of being able to change the 1 MILLISECOND DEFAULT setting of the usb drive polling by creating the new Dword called "IdleEnable.

Hi,
I am trying to use WinPcap (A packet sniffer) with my laptop using a wireless connection seems like this type of adapter (wireless) is not supported by The WinPcap product
On thier FAQ page they ( the WinPcap people ) mention in order to get around the problem of Unsupported Adapters
you can try a NetWork Bridge using Adapter on the Computer you are trying to Form a Network Bridge with
Seems like from the tutorial On Windows you would 2 NetWork connections on the LapTop to get a NetWok Bridge
Would any have any info a how to go about this Meaning form a bridge connection between a WireLess Adapter on
the Laptop and a Tower connected to a router

Hi, my server is running with a partition that contain 200Gb of disk space with 190Gb of data. I found that the partition is dirty so I need to scan disk. But I'm not sure how long should it take. The scan disk option will include fix error on disk and check for bad sector (here is the syntax chkdsk e: -r -f). Could anyone please let me know how long should it take for this scan disk process? Because I want to have a proper schedule to scan it without impact to the user. Thank in advance!!!

Only you can answer this question. We know nothing of the disk configuration, number of files and folders, system speed, processor specs, disk interface, ..., nothing. We still couldn't tell you, even if we did know this stuff. There's just no way to predict it.
You just have to do it once at night, see how long it takes, and schedule it appropriately.

The problem that I face is the electricity for my office just avaialable only between 7am to 7pm from Monday through Friday only. So during most of this time, user need to connect to the server to work with the shared file, we only have two hours at lunch time but I don't think 2 hours will enough for me to scan disk. I post the question in here whether anyone know are there any tool design to calculate the estimate time for the scan disk process. Thank you for your comment!!!

No, there isn't any tool that will estimate this, because, like us, there's no way for it to predict what is happening during a scan and how fast it's going to go.
You also don't have to scan the disk every night, or every week. Once a month is good.

As Dave has already said there is no way to find out how long time it might take. But you can make an estimation on what it will atleast take.
First take a very large contiguous file, copy it to another place on the harddrive and calculate how fast your drive is.
For example: if copying 600MB takes 20 seconds you have a speed of 30 MB/s.
What NTFS is doing when you copy a file is reading it in one place, writing it in another place and reading it again in this new place to check if it's correct.
Coincidentally this is (very) simplified what the surface check is doing too.
So if your speed is 30 MB/s it will take atleast 6700 s, which is just a little less than two hours, to control the disk.
This is a physically limited minimum time. On top of this the file system is also checked.
And if there are any problems the whole process might seriously slow down to anything but a stop.

Difficult to tell since it can vary depending on many hardware factors.

Probably best to schedule it right after the end of business day, and that can vary from organization to organization. You have to hope that the scheduled tasks end before the next business day begins. A client of mine, ends their business day about 3:30-3:45pm or so, and I schedule all of the maintenance tasks after about 4:00pm.

In Device Manager, if you expand the Universal Serial Bus controllers node, you see a list of host controllers and hubs. How can I tell what type of device (e.g., mouse, keyboard, flash drive) is connected to a port?
Thanks.

Have you clicked your way through the tree down to the USB Hubs?
In the case of my computer:
ACPI Multiprocessor PC -> Microsoft ACPI-Compliant System -> PCI Bus -> Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller -> USB Root Hub -> Generic USB Hub -> Generic USB Hub -> USB Composite Device -> USB Human Interface Device -> HID Keyboard device.
Otherwise I'm sorry if I have misunderstood your question.

No, I had not. After drilling all the way down (I was originally looking for something near the top level), it finds the devices in question. Thanks for the clarification.

I have a WML (inside vbscript) query using a WHERE clause, as in the following:
SELECT * FROM SomeClass WHERE someproperty = somevalue
The problem that I have is figuring out a way to see if the query matches or not. I cannot use the Count property (I get an invalid query error message). Is Nothing an IsNull do not work either, whether it is on the object or its Item property.
Typename on the variable returns SWbemObjectSet
|
|

|

SWbemObjectSet has the Count property. For example, this script:
Set objWMI = GetObject _
("winmgmts:root\cimv2")
Set colDisks = objWMI.ExecQuery _
("Select * From Win32_LogicalDisk " _
& "Where DeviceId = 'C:'")
WScript.Echo colDisks.Count
will return 1. Count is not accessible when you use SWbemServices.ExecQuery with the wbemFlagForwardOnly flag:
Set objWMI = GetObject _
("winmgmts:root\cimv2")
Set colDisks = objWMI.ExecQuery _
("Select * From Win32_LogicalDisk " _
& "Where DeviceId = 'C:'", , 48)
WScript.Echo colDisks.Count
This script returns this error:
SWbemObjectSet: Unspecified error
but it is difficult to guess what is wrong without seeing any code.
Is Nothing and IsNull don't help either because an empty result set is still a valid SWbemObjectSet object:
Set objWMI = GetObject _
("winmgmts:root\cimv2")
Set colDisks = objWMI.ExecQuery _
("Select * From Win32_LogicalDisk " _
& "Where DeviceId = 'Blah'")
WScript.Echo colDisks.Count
WScript.Echo TypeName(colDisks)
WScript.Echo CStr(colDisks Is Nothing)
WScript.Echo CStr(IsNull(colDisks))

There you go:
Option Explicit
Sub CreateHost (HostName, HostType, NTGroupName, AuthTrusted)
On Error Resume Next
Dim objLocator, objService, objHostSetting, objHS, objBTSHost
' Connects to local server WMI Provider BizTalk namespace
Set objLocator = Createobject ("wbemScripting.SWbemLocator")
Set objService = objLocator.ConnectServer(".", "root/MicrosoftBizTalkServer")
if err <> 0 then
wscript.echo "Error Point 1: " & Err.Description
end if
set objBTSHost = objService.ExecQuery("select * from MSBTS_Host where Name = " & HostName)
if err <> 0 then
wscript.echo "Error Point 2: " & Err.Description
end if
wscript.echo objBTSHost.Count
if err <> 0 then
wscript.echo "Error Point 3: " & Err.Description
end if
' More code after this
' ....
end Sub
On Error Resume Next
' Create a host, an instance of it, and associate.
CreateHost "MyHost", 1, "BizTalk Application Users", false
This produces the following output:
Error Point 3: Invalid query.
Thanks.

HostName seems to be a string, so try to enclose it in single quotes:
"Select * From MSBTS_Host Where Name = '" & HostName & "'"

Dear all,
I have Windows Vista Ente. 32 bit running on Intel Core 2 Quad CPU Q6700, 2.66 Ghz cpu, $G ram .
After joining the machine to the domain, it takes about 15 minutes for the O.S. to load, its becomming too slowwww.
Any Ideas about the problem? solutions?
Best regards.

So what is the machine doing during these 15 minutes? How long does it take if not a member of a domain?
