Hi
The problem started after the installation or removal of the "Active Directory"?
|
|
|
|
|
check access to directory:
C:\WINDOWS\system32\config
using other tools for open files evt

I noticed that there is a dword in the regedit located at HKCCONFIG > software > microsoft > windows > current version > internet settings --- and that the default value setting on my xp sp2 has it set at a value of 0 which I assume means that the proxy is turned off - so I changed the value to 1 which should turn it back on, which seems the more logical thing to do.
Do xp sp2 cd disks all come with that setting set at zero?
I do not have any windows updates installed on the computer although I did a bios update ,A01 revision download onto my Dell computer, unfortunately,from the Dell site; and also recently I installed ubuntu 8.04 and the newer 9 version temporarily onto my computer from ubuntu cd disks-- and they all did some modifications to my xp sp2 operating system and I wonder if that accounts for that ProxyEnable default setting?Can someone tell me if that default setting of zero is what all xp sp2 cd disks [Home Edition] come with?
- thanks, winch1020

Yes, the Proxy settings are off by default. Well, I should say that it's probably "AutoDetect".
There is more than one registry value that controls the proxy settings. Just changing that one value alone won't do much. If there is no data in corresponding values, then what you did was invalidate the setting and IE might just ignore it, or reset it back to a know state.

Hi, by configure each client machine with ISP DNS IP to access an internet and configure each client machine with internal DNS server (and this DNS server forward the request to ISP DNS server), which method that will apply to the below situation:
1. Decrease internet usage
2. Decrease network bandwidth
Thank,

No. I'm desing a network for my office. Currently I configure each client with primary DNS to my DNS server and secondary DNS to ISP DNS server. The day before yesterday my internet usage in my office is 2200 Mb which is 50% of my internet plan per month. Because I didn't deploy ISA yet, i could not know who was using an internet. So I just want to know which method of configure DNS setting at the client site that will help me to reduce network traffic.
PS: Currently I didn't study any course. I'm a person which is study by myself from the book of Microsoft Press. Whether I took Microsoft Exam, I don't have any chance to get out of the room to post the question for the solution on internet.

You should probably remove the ISP DNS entry from the workstations. You are probably forwarding local domain queries to your ISP. For example, user John wants to access the fileserver at FILESERVER.MYLOCALDOMAIN and your ISP is not authoritative for MYLOCALDOMAIN and generates a negative response.
If you have a single office domain and a single DNS server serving all requests for both LAN and WAN then you should probably configure your local DNS server as authoritative for MYLOCALDOMAIN and completely disable forwarding. Then you need to configure the DNS server to use root hints. Using root hints will make your DNS server not rely on the upstream DNS provider.

Yeah, remove the ISP DNS from the clients.
But, in any case, that's not going to reduce the traffic to the ISP by that much. A query is only 60 bytes, and you can't possibly make that may queries to account for that much bandwidth.
If every client has a direct connection to the router connected to the internet, you've got a problem. You need to reconfigure the network so that the only box that has the connection to the internet is the ISA box. Every client then has to be configured to use the ISA box as a proxy server. Only then can you track who's using the internet connection.

Thank you very much for your answer. Currently all of my client are connect directly to the internet with router as a default gateway and primary dns point to internal domain with the secondary DNS point to ISP. I do that because sometime my domain is not available to the user due to electricity problem. Next month I plan to deploy ISA server which would be remove this problem.

Obviously the internal DNS server will cache the query and return the cached result on subsequent internal requests. A DNS query is 60 bytes in size so you would decrease network bandwidth by 60 bytes * the number of duplicate DNS queries. There are other factors involved such as DNS cache timeout and such.

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.
