We have two broadband routers providing internet connections for our office. How do I setup my gateways on the our office nodes (XP Pro), so that we can access internet even when one fails.
The problem is that since these routers are always available, but their internet links may fail at times. Therefore, if I have the first router as my gateway, and its internet link fails, I cannot connect to the internet. This despite that I have a second gateway configured on my PC pointing to the second router.
From what I have found, Windows passes on my requests to the first gateway as it is available, which cannot locate the server I am trying to connect, because its link is down. Hence, my connection fails. So, how can I setup a routing configuration such that my PC can transparently switch over to the second router when the first one's internet link goes down?
Also, how can I implement some kind of load balancing, so that some nodes are routed thru router#1 and some thru router#2 when both are available?
Thanks!

Hello!
First you need some basic routing skills for you to solve this. You should place the routers within the same network, then add routes with equal metrics, therefore if one link goes down, the routers should communicate with each other so that they pass traffic to the available gateway (in Cisco routers, CDP does this-it updates neighbouring routers of the status of one another). For eg if you have router a and b, incase router a is down, router a will receive traffic from the client pcs and since its status is down it will route traffic to router b, it knows the status of b, up. When both links are up, you can use static routes to direct traffic to the interfaces on your routers depending on the size of your network. This can balance your load.

Does anyone have any ideas on how to detect from a UNC share how remote (or fast) it is, i.e. is it on LAN or WAN etc?
I need to be able to look at a list of UNCs and determine the fastest accessible one, to use for storing some temporary files for fast access by client apps.
I have tried using MultinetGetConnectionPerformance to determine the connection speed, but it doesn't return sensible results.

Other than doing a ICMP ping to the target box, there's no real way to do this. No matter what you use though, there is nothing that takes into account the load on the target box. So, you may have a quick TCP/IP path to it, but the box is too busy to respond in a timely fashion.

Thanks for your reply.
This makes perfect sense - I hadn't taken into account the time for a machine to pull it's finger out and get around to responding!
I had another couple of thoughts though: Given that all I want to do is to offer a user a reasonably sensible default server share to use for storing 'local-ish' cached data, from a list of admin-configured possibilities, what about either finding out where the server is geographically, and seeing which is closest to the client, or even finding out the server's time zone, and using the one with the smallest offset from the client? Not sure if either of these are possible or feasible. Any ideas?

Well, timezone doesn't guarantee localness.
A method that I though about would be to generate a table of primary and alternate cache servers using IP network information. The application could get it's own IP address and subnet, figure out it's network address, then lookup in this table what the closest cache server would be and use that. If the first cache server fails, the alternate could be used.
Or, the list of cache server could be used so the client could tracert to each server and figure out the closest server by hop count, and alternatively, by response time of the pings going to it. Maybe even a weighted evaluation of connection quality. This, of course, would take a considerable amount of time compared to other schemes, but is possible to do with shorted cache server lists, maybe even limited by the user picking a geographic region.

Many thanks for the info. It gives us some other things to play with, though given that we're only in practice looking at two or three alternative servers, I think for now we'll probably just ask the user to choose which one to use the first time they need it!

not sure if it will help.... but http://www.partition-recovery.com/[^] active @ partition saved my behind once when a drive was erased.... saved all but two files....
unfortunately, resetting back to factory conditions is a destructive operation that generally includes format and file copy from the recovery image. The format is only partially destructive, depending on the format tool and options, but the file copy is always destructive. Anything that was under those clusters now occupied by the new factory condition image is lost to everyone but a forensic computer tech. I have heard that forensic analysis of a disk can bring back the last 10+ copies of the data that was on any given cluster, but it is expensive, extremely expensive.
there are also these: http://www.thefreecountry.com/utilities/datarecovery.shtml[^]

Testdisk and Photorec are your friends.
Photorec is intended to recover pictures, movies and musik from flash-drives, but does a good job on other drives as well.
Testdisk can recover lost partitions (not sure if that was your problem).
These two are a "must have". Seriously. If you haven't heard of them, get them.
Cheers,

Hi,
Here is the situation:
I have 2 computers with WINXP.
And one Pocket PC with windows mobile 2003.
I'm developing a network socket application...
The application is running on one computer and pocket PC.
The application works ( I can test it ) on the 2 computers.
Now I need to test it on the pocket PC, and the PPC must have a internet connection, which he gets by connecting to one of the computers through ActiveSync.
So the PPC is connected to one of the computers while the other computer sends data to the other computer.
But the PPC doesn't receive that data because ActiveSync is on another port, and the application opens a port (8000) on the pocket PC not on the computer...
So how could I route all data that is coming to a PC (only the data that is coming on port 8000, on which the pocket PC is connected) to the pocket PC port 8000, which is connected through USB ActiveSync connection?
I know this is quite complicating...
But please if you can help...
Thank you!

Hi,
Kindly let me know that, Is there any dangerous points to use Hibernate option in windows XP when I turn on my computer more than 1 day?
or
Should I use Hibernate option always when I do not want to wait much time when computer takes several time to load heavy applications/resources?
Thank you in advance

Hi Riaz,
Please know that the benefit of hibernating your computer is that you are saving energy by having minimal power on. It doesn't shut your machine on, so you don't have to wait as long for the OS to load up.
This disadvantages of hibernation is that the system can have a lot of issues pulling out of hibernation. Of course, as time goes on, machines are getting better and better so this becomes less of an issue.
Keep in mind that you need about 3-4 GB of free Hard Disk space to enable hibernation. So if you are limited on space, you might want to think about not enabling it.
It's really just a user's preference. The Hibernation mode is more desirable if you're going to be going to be away from the computer for an extended time period, otherwise you could use the Standby mode.
I hope this helps  .

There is a related query I was just wanting to ask. If we use Windows Hibernation feature as a regular use, would it have any ill-effect on hard-disk.
One of my friend actually was telling in that perspective and it is a bad feature to use. But I feel it is a hibernate.sys file which is being created (size equal to the disk volume), it should not have any such effects?
Can you help clarify this too?

No, there are no ill-effects on the disk. The hybernate.sys file is the same as any other, just bigger.
THe problem with hybernate is that some applications and drivers don't recover from hybernation very well. A rather common example of this is some wireless network cards cannot reconnect to the network, especially if wireless encryption is used.

Hibernate is nothing but it just copies what ever in your RAM in to harddrive (in hibernate.sys file). this file's size is same as your RAM size. When system wakes up it will copies every thing from hibernate.sys into RAM.
So this doesnt affect your harddrive or any other things.
System stage will be same as it was hibernated (as it rollback everything into your RAM).

I'm debugging an application. Sometimes it hangs so that I can't kill it from TaskManager. What's more, the computer loses the ability to access network drives, and some other actions become terribly slow (sometimes running cmd.exe from TaskManager takes a lot of time). Also, I can't connect to Remote Debugger on that computer.
Any suggestions? Can it have to do with trying to open a file locked by some other process on another computer? Or with running ~160 threads?

Hey guys,
Ive been shipped a development PC from Germany, and the version of XP installed does not have support for US english. I've been all over the MS support site, and suprise surprise, there isnt a topic or answer that helps me solve my problem...
I cannot reinstall windows on this computer. It has all of the devopment tools and settings already installed and set, but everything is in German... Is there a single download for multi language support so i can switch the language to english while i have the computer? Ive set every possible option to english, but when i try to switch the menus and the other remaining options to english it begins searching for an \i386\lang folder that does not exist. Any ideas?

IIRC, these files are there in the windows XP installation CD. If you have one, then try setting options again after inserting the CD.

I'm surprised that English isn't there by default, i.e. without having to install specific English versions of DLLs from the Windows CD.
You could try 'forcing' the issue by setting the UI language in the registry, it's a fairly quick change and shouldn't have nay adverse effects:
Add a string value for the language you want to use to HKLM\System\CurrentControlSet\Control\Nls\MUILanguages with the name being the hex language id for English US (0409) and set the value to 1.
That makes English US available and determines what is displayed in the 'Language used in menus and dialogs' drop down on the 'Languages' page in regional settings in the control panel.
From your posting I gather that it's when you change this that it starts asking for the cd. In that case, you can force the change by changing the following registry value:
HKEY_CURRENT_USER\Control Panel\Desktop<br />
MultiUILanguageId
to 00000409
The effect of this should be instant, in that, if you open a windows dialog, you should see OK and Cancel buttons in English now. Do a restart and hopefully most strings will be in English.
Hth,
JK

hmmm... ive tried both, neither seem to work, i think i may just need to get an xp cd...
i had to add both keys to the registry there no MUILLanguages string, i did a search on the whole registry, so i added it at the path suggested and the value to it
also i tried option2 with the same resultsm, i guess i may need that XP CD

You need the MUI-disks I believe. Windows XP comes in a special version with all languages, but you can use MUI-disks with any XP installation.

I have been working with multilanguage. Since a customer of mine is multinational they have some computers around with multilanguage on them.
You're not gonna like this though. Multilingual user interface can only be installed on top of an English Windows XP.
There's more info about it on technet[^]
As a reinstall is out of the question I wish you good luck in learning German

Anyone ever configure SNMP for a windows 2003 box? I have gotten the "lucky" job having to do this, and I'm pretty clueless. I have the services installed and running, but beyond that I'm still trying to dig stuff up. Any suggestions, good articles, etc?
