Thank you for your respond, is it possible for me to increase the size of DNS query? If it is possible, where could I configure it?

Not sure what your asking... Extended DNS[^] can be enabled to support oversized DNS messages.
Anyway,I looked at my response to your post yesterday and can see that I was also not completely correct. By using an internal caching DNS server you will save somewhere around 60 bytes of the query and 436 - 512 bytes of the response multiplied by the number of duplicate queries.

Ok, it seems that the standard windows belief is that Virtual Memory = Pagefile/Swapfile.
However, this isn't the case (searching bing/google will result in a ton of posts by microsoft MVPs indicating this but none of them bother to actually explain anything other than "don't mess with it if you don't know what you are doing"). Well, I'm trying to learn what I'm doing here and what I've found certainly agrees with what they are saying. For example, if you completely disable the pagefile on a machine, taskmanager still reports programs using virtual memory.
So other than the pagefile, where does windows store virtual memory? Is it still on the hard drive in some unmanagable location? Or is it in RAM that is reserved for the OS? Or is it in RAM but simply non-contiguous from the rest of the memory allocated for an application and the number displayed in task manager is simply displaying total memory used by the application minus the initial allocation?
Anyone have any good sites that actually explain what the virtual memory manager in windows is doing? apparently it is one of the oldest concepts in computing yet noone seems to know anything about it.

Hi,
there are two parts to virtual memory:
1.
your app uses "logical addresses", your machine's hardware provides memory located at some "physical addresses". These don't have to correspond in a one-to-one relation because the MMU (Memory Management Unit, part of the CPU) translates logical-to-physical.
Without a memory extension (as in pagefile/swapfile) your app can have as much logical memory as it is allotted physical memory (the "working set"), while the logical addresses don't need to be consecutive. The advantage is your app can set up different data structures (e.g. stacks) with some initial size, and grow them as needed (until the working set is exhausted).
2.
when you add a swap file/page file to the system, your app now can have more logical address space than it is allotted physical address space; the extra space is allocated in the file on disk. Furthermore the app's working set can be adjusted dynamically, e.g. a Windows app that loses focus (e.g. main form gets minimized) will have its working set reduced, hence the excess physical memory is copied to the page file and becomes available to some other process.

Available virtual memory = physical RAM + swap file size. Disabling the swap file just reduces the total amount of virtual memory that can be in use at once. Also, disabling swap doesn't prevent programs from opening a file and mapping it into memory with MapViewOfFile().
You'll always see virtual memory in use because all addresses in user space are virtual addresses. That's one of the parts of the mechanism that gives each process its own address space.

Everyone,
I'm in trouble now. Last few days, any client cannot access to server as often. When I try to ping to server (DHCP Server) from client it doesn't reply but when I ping from server to client it replies normally. I'd changed the client ip to static ip, but it still cannot ping to server. On server, I reconfigure new DHCP but clients still cannot get IP.
So, how to solve the problem??????

Once you have set a Static Address in the correct subnet double check the DHCP server to make sure there is no active lease for that address.
From the command line try running tracert to the DHCP server. This should show you were the traffic is dying.
There is a lot of missing information here. Once you have a static address can you ping other resources? Is your network driver installed properly? Can you ping your default gateway? Etc, Etc.

Hi, does anyone know how to disable blue screen error in Windows XP? I mean if windows cause a problem and will display blue screen error, its will ignore this and operate as normal.
Thank in advance!!!

You can't disable it. You can prevent XP from restarting though.
The reason you're getting the Blue Screen is because the kernel cannot get back to a "normal" state. Something went seriously wrong and caused the kernel to panic. It halts the system to prevent system instability from corrupting existing data.

Thank you for your information. I know how to disable auto restart but i don't know how to disable it.

Dear all,
I have HP pavilion laptop, running XP SP3, the problem started like this, after normal opeartion on the laptop i turned it off, the other day wana turned on, after the welcome screen a window pops up:
logonui.exe - Application error. the instruction at "oxxx5ft0664" referenced memory at "0x005ft0664". The memory could not be "written". with OK and CANCEL buttons. after many clicks on the OK or CANCEL buttons, the window disappears and the laptop shows only the desktop background without any icons, any toolbar without any thing.
Try the Alt+Ctrl+Del, it says the taskmanager is disabled.
I googled, most results defines this file, but no result on how to solve the prob.
Any help guys, URGENT.

Since yesterday am not lucky with a solution, think of backing up data and a format then Vista installation.
Thanks again,
best regards.

No, I was referring to this website[^]. The third or fourth post down deal with how to do a repair installation of Windows using any XP-CD.
If you don't have an XP-CD, you're out of luck.

Sebastian

Hi, I have install adobe acrobat on my computer which is already have some adobe acrobat document. Once I have install successfully, when I try to open the file, windows display the dialog to open the file with and I select acrobat. The document was open successfully but the problem is, it is not remember an application to open PDF file. Once I double click on the file again, its still asked me to open the file with dialogbox. I don't know what is the cause of the problem. Could anyone let me know what is the cause of the problem and how to fix it?
Thank in advance!!!

The file type didn't get registered during the installation.
So either you uninstall and reinstall the program (there might be other errors after all),
or you register the filetype manually.
For WinXP, start explorer.exe and select folder options from the tools menu, then select the filetypes tab.
Here you can add, remove or change the filetypes and what programs to use for different actions.

Thank you very much for your advice. I will try to do that and if I need any help I will let you know. Thank

One thing that I forget to tell you. Open I open the PDF file, I already select on the check box Always open the select program to opne this type of file. But the file still not remember to open with adobe acrobat file. Thank
|

I've seen that happen, too. The registry is probably a little confused and needs a good spanking with a wrench or tyre-iron (read: Remove all PDF-related entries, then reinstall).
Cheers,
Sebastian
