Hello,
I’ve been trying from my local computer to access to another’s Machine WMI.
In my machine I have windows XP installed, but the other machine has windows 2000 installed.
Till now, I’ve been able to access the WMI on the machine with the windows 2000, using several classes (Win32_LogicalDisk; Win32_Service and Win32_Process)
Now I’m trying to get information about terminal sessions on the computer (Name of the machine that is connecting...etc.) with the windows 2000 accessing its WMI from my computer. However this doesn’t seem to be working, I get a 0x80041010 error in line 18 column 1 (see code below). I was able to see that this error is: “Specified class is invalid.”. So I guess the problem is that the WIN32_ServerSession doesn’t exist in the machine with the windows 2000.
Using wbemtest.exe, I realized that the class WIN32_ServerSession doesn’t exist in the machine with windows 2000. However the required files (cimwin32.dll, cimwin32.mfl and cimwin32.mof) exist in the directory \WINDOWS\system32\wbem. How can I add this class to the WMI? Do you think this might be the problem?
I’m a little inexperienced in WMI, so I’m not quite sure to what’s the reason of the problem. Can you please aid getting this to work?
Best Regards,
Nuno Pedro

You can't add the Win32_ServerSession class to the Windows 2000 box. This is because the Win32 API functions required to support that class don't exist in Windows 2000! Server-side, they only exist in Longhorn and Windows 2003.
In other words, you can't use that class at all on Windows 2000 and you can't force it to work either!

Tks for the help but I've read that page too... (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/win32_serversession.asp)
However what I would really like to know is how you extend/Add that class to WMI namespace. Is there anyway to do this?

One more time... YOU CAN'T!!!!!
The Win32 API functions, required to make that WMI class actually work on your server, doesn't exist in Windows 2000 and CANNOT BE ADDED TO IT TO MAKE IT WORK!
WMI classes are WRAPPERS for the operating systems API functions, drivers, collections, drives, ... If the API functions don't exist, the WMI classes that wrap them won't work either.
That's why, at the bottom of that page, it says Longhorn and Windows 2003 and above ONLY.

Hi there,
I had been for over 3 days trying to solve this problem and I have no clue of what's wrong.
I'm trying to create a Dynamic DNS service using only one DNS Server (dns.firmaware.com), but created a second NS record (dns2.firmaware.com) with the same IP address.
First of all I've created a small app in VB .net that updates (using WMI) Microsoft DNS Server whenever an IP change was reported.
It creates different zones for each sub-domain and adds NS records, updates SOA record to change the TTL and MinimumTTL and finally adds/updates the A record.
I know that zone creation/update is working fine because I tested my VB .net several times and checked that Microsoft DNS entries were created/updated.
After checking all that I created a record like “test.gimmeall.com” and resolved it from my home PC. Using “ipconfig /displaydns” I checked that “test.gimmeall.com” had the following values:
localhost
----------------------------------------
Record data . . . . . : test.gimmeall.com
Record type . . . . . : 1
TTL . . . . . . . . . . . : 60
Data length. . . : 4
Section. . . . . . . . . . : Answer
A record (host) . . : 213.13.100.111
So, TTL was fine, if I changed test.gimmeall.com’s A record, after 60 seconds it would be updated, BUT that’s not happening because, after my update, when I ping the same host again it returns the same IP address and when I type “ipconfig /displaydns” it returns the following result:
----------------------------------------
Record data . . . . . : test.gimmeall.com
Record type . . . . . : 1
TTL . . . . . . . . . . . : 85823
Data length. . . : 4
Section. . . . . . . . . . : Answer
A record (host) . . : 213.13.100.111
It looks like that ISP or something else is caching “test.gimmeall.com” with invalid values, but it’s not an ISP problem because tried from different ISP companies and always had the same result.
Can you help me please?
I would be very thankful.
Regards,
Filipe Freire

What is the minimum and maximum size for the Virtual Memory in WinXP and Win2000
and other Windows in general?

Maximum size for Virtual memory is how much free space you have on C:\
And minimal size it depends, how much RAM you have and what process you are running.

Well, not exactly. A quick calculation is your physical RAM + the size of all swap files.

I have made a little mistake. When i looked i can set up to 4096MB maximum on each partition, And Minimal 2MB.

I think you made a mistake with this calculation.

My guess is that you can only use 4096 MB since that is all that is addressable with your processor (32Bit ~= 4 Gig). I bet you can make it quite a bit higher on a 64 Bit machine

This is normally done on the firewall, not the PC.
Putting the burden on the PC, depending on your environment, can be a pain at best, and a total nightmare at worst.
This is because the amount of administration in a workgroup environment with no roaming profiles will force you to make the change for the user on each and every PC that the person logs onto.
In a domain environment, with Group Policies in effect, it's better, but is still a pain because of the maintenance of the denied list and making sure that the policies are set up correctly.
The best way to do it is a firewall where the user needs to authenticate to the firewall to get to an outside site. This way you just need to make the change in one place and not worry about the configuration of the machines themselves.

I have a Windows XP Professional but whenever I was trying to open my computer with a right click it shows an error. MMC requires Internet Explorer 5.5 or greater to be installed.
Please tell me how can I install greater. I was trying to installed IE6 but it says you have a latest version al:(ready installed.
thanx....vim

do you really have IE6 installed? check the version
also, go to the windows update site & get all the latest patches

XP comes with IE 6 installed already. You can't have any lower versions installed.
The problem doesn't appear to be a documneted issue with Microsoft. I would try scanning your machine for spyware/viruses and removing as much as possible.

I have a machine that for no apparent reason started ringing the bell, like a railway crossing signal but a bit faster. This happened before and when I moved it to my lab to take a look inside the box it decided to work without my doing anything except move some wires around so I could feel if any of the various connectors were loose. This leads me to believe that it is a loose connector but I don’t know which.
The ringing starts when there is normally a single beep but doesn’t stop and the boot doesn't progress to where anything is written to the screen. I did swap the video driver with one I know to work on another machine and that was not the problem. I disconnected boards one by one but that didn't have any effect either.
What is the absolute first thing to happen after the single bell sounds when a machine is booting before anything is written to the screen?
Does anyone have similar experiences and can suggest what the most probable cause of this problem is?
Thanks for any advice you can give me.

It sounds like your machine hung during the boot. The sound card just started playing the same sound over and over again because it wasn'ttold to stop or wasnt given anything else to do.
Do you have any "inflated" capacitors on you motherboard? Google for "Capacitor plague" for what I'm talking about.

Thanks, I wasn't aware of this problem. I'll have to take a good look at the MB and power supply.
Do you happen to know where I can locate a writeup on MB test points? I am just getting back into diagnosing hardware, after many years, but do not have the engineering specs for the boards I need to check out.

It is also possible that the cause is a hardware failure. Check your PC or motherboard manual for error codes. Error conditions are indicated by different beep patterns.

You're really not going to find anything useful. This stuff is proprietary to the manufacturer for each design. No-one publishes the stuff.

I came across the following syntax in a batch file (runs on XP, probably on any NT version)
type filename.ext || echo error
The result is that if filename.ext exists, its contents are listed, but if it doesn't, the second command (echo error) is executed
The same is true of any command other than type and echo, meaning that the part after || is executed only if the first command fails.
This feels like an incredibly stupid question, but what exactly does || do? I know that | is the pipe operator... 
Seaching the web came up with this wonderful site which gives all kinds of batch file examples & tips, but I can't find the above
http://www.robvanderwoude.com/[^]
This is off topic, but I even found out that it is now possible to write subroutines in batch files, using call :label & goto :eof  ...

 Conditional Commands
When an internal command or external program finishes, it returns a result called the exit code. Conditional commands allow you to perform tasks based upon the previous command's exit code. Many programs return a 0 if they are successful and a non-zero value if they encounter an error.
If you separate two commands by && (AND), the second command will be executed only if the first returns an exit code of 0. For example, the following command will only erase files if the BACKUP operation succeeds:
[c:\] backup c:\ a: && del c:\*.bak;*.lst
If you separate two commands by || (OR), the second command will be executed only if the first returns a non-zero exit code. For example, if the following BACKUP operation fails, then ECHO will display a message:
[c:\] backup c:\ a: || echo Error in the backup!
All internal commands return an exit code, but not all external programs do. Conditional commands will behave unpredictably if you use them with external programs which do not return an explicit exit code. To determine whether a particular external program returns a meaningful exit code use an ECHO %? command immediately after the program is finished. If the program's documentation does not discuss exit codes you may need to experiment with a variety of conditions to see how the exit code changes. Note that this is backwards from the C/Perl meaning of && and ||, because in DOS, 0 = succes but in C, 0 = failure.

so it is the logical OR operator. wonder why it doesn't appear anywhere in cmd.exe's help (or maybe I missed it...)
thank you!

which is why main() used to return 0 on success in old DOS programs... 
[edit] not only in DOS but all programs. using MFC made me forget that.[/edit]
kind of confusing, isn't it...
4NT[^] looks useful. I'm looking in to that too. Thanks again!
