well! i have a problem which is a bit different from the general mood of questions here!
I have a client server application for which i want to calculate that:
in order to serve 40 client connections (doing file transfers with average file size being 3MB),
for which the clients must be having a download speed of atleast 4KB/sec
how much bandwidth must be allocated at the server side so that it server those 40 clients well!
I want answer to this specific quiestion and if some one can give me a formula for this i'll be very thankful.

((40 * 4) * 8) = 1280 bits pr. second. Which is a 1.25 Mbit network

Windows XP has a (supposedly) handy feature called "rollback" where you can undo operations you've done and go back to the way the system was before.
Question: sometimes this doesn't work! Sometimes you can "roll back" to a rollback point, but if you examine your system, the rollback clearly did not work properly - files that were created after the rollback point are still there, some registry settings weren't rolled back, etc.
This only happens sometimes. So far I've only seen it on XP home, but I can't be sure it's just an XP home issue (I always thought XP Home and XP pro were really pretty much the same, just in a different box.)
So what might be wrong? Could there be something wrong with the rollback point? Or do you have to do something special (besides just keeping the rollback feature on) to get this to work? Or might it be an OS problem?
Any general info about rolling back would be appreciated. This is a baffling problem.
There are three types of people in this world: those who can count, and those who can't.

Hello,

thanks.

oh my god ! I forgot the password of windows 2000 server installed on my computer
now what to do?

Were you using the administrator account? If you were then shame on you... you forgot that account 
Connect the drive up to another system pull off the data and start over....
If not, just log on as administrator and rest the account that you were using.

I have a Win2K pro peer-to-peer network. Most of the workstations can access one another's shares flawlessly, but a few cannot. I am having a hard time figuring out what is causing the anomalies.
How can I find out the reason a user's authorization is denied on a given machine? I have three machines: \\foo, \\bar, and \\mew.
I can access both \\foo and \\bar from \\mew, using the same account and password, but I cannot access \\foo from \\bar (error says "unknown user or bad password"). Can anyone give me some pointers on figuring out why the user's access is not being authorized. The Event Log events are quite uninformative to my eyes.

mainly because I haven't got a clue how it works.
I have a small (8 client) home network with one windows 2000 server. I also have ADSL with a dynamic IP address (actually never changes). My network is on 192.168.0.x with each client given an IP address through the DHCP server on the ADSL router. The ADSL router and Win2K server have static IPs within the 192.168.0.x range but not in the same scope as the DHCP. Clear so far?
At present the clients are all configured with their gateway as the ADSL router and their DNS servers as the ISP's DNS servers. This is a bit diodgy as in theory the Win2k server should be set up as the primary DNS and then delgate any requets it can't handle to the ISP's DNS servers but I couldn't figure out how to do that  (any help much appreciated).
Anyway, I get home today and my client machines can't connect to the internet. More exactly, they can't resolve the host names into IP addresses. Using IP addresses is OK.
What makes it wierd is that the Win2K server can still resolve hostnames fine. The only real difference between this machine and the clients is that it has a static IP. The DNS servers are setup the same as the clients.
Anyway, does anyone have some idea about what I should do to fix this?
Cheers
James

Has the Win2k server been running continuously? It caches any DNS searches and uses the cached addresses if it can't connect to the ISP's servers.

It has been running continuouslybut I just tested this theory by putting in a few web addresses that I've never been to before and it found them straightaway. Must be something else...

Change the setup...
DSL -> Router -> server_external_nic -> server -> server_internal_nic -> Hub -> clients
Keep the external networjk set up as the same subnet that teh router wants to use (192.168.0.1 or 10.0.0.1 are popular).
Give all clients a static IP address (you only have 8 clients so that should not be tooo hard).
Read up in the NT userguide for NAT.
Set up your own local DNS (you will have to do this if you use Active Directory to authenticate clients anyway) and set the forwarders of that server to your ISP DNS servers.
Basically this is the best way to set up.. you can use the server as a secondary router and authenticate all your users off of it.
I use the setup in my home office with a cable internet conneciton and it works great. I run a copy of Microsoft Small Business Server 2000 (Exchange, ISA Server, SQL, the works) and things run fantastic.

Hi all,
I wrote a service for w2k.
But there are something wrong in the ServiceMain() function. because I can not start this service but when i simplize ServiceMain() It works ok. ( I start another thread in the ServiceMain() and call DeviceIoControl() in it). I want to debug the ServiceMain(). But don't know how to do it. I only know how to start and debug the Service control code in another project.
Thanks for help. I am very anxious

This is a programming question and should better reside in the Visual C++ forum. 
Having said that, here is the solution:
#define HARDBREAK __asm int 3
void WINAPI ServiceMain( DWORD dwArgc, LPTSTR* apszArgs )
{
...
HARDBREAK;
...
}
The above HARDBREAK macro inserts a hard-coded breakpoint into your code. (Software interrupt 3 is used for breakpoints on x86). If you run your service (via SCM) and control reaches this possition a "Unhandled exception" message box of windows will appear. Choose cancle to debug your app and - voila you will find yourself in the debugger with the app halted as exactly this position. From there you could single-step, insert watches, etc.
Please post any F-ups to this to the Visual C++ Forum

Does anyone know of an app, or how, I can access the temperature sensor in my new HD? It is a Seagate 80GB Barracuda.

I saw such an app on http://fileforum.betanews.com/[^] a while back.
But I can't remember what it was called or if it was any good Sorry.

This isn't it (the one that I saw prev.) but maybe it'll do what you're looking for
Active SMART Monitor[^]
Active SMART Monitor is a full-featured failure-prediction agent. Sitting in the system tray, it monitors hard disks and alerts you to impending failure. The program uses Self Monitoring and Reporting Technology (S.M.A.R.T.) built into all new hard disks, and can predict failures on your hard drives. A host of alerting features include email, local pop-up messages, net messages, and event logging, while using no system resources.
Changes in Current Version:
* Label formatting fixed
* Additional attribute codes added
* Temperature support added

I'm not sure how accurate the temperature is. It is reporting 35 F which seems highly unlikely, but 35 C sounds about right. It could be a typo.
You wouldn't have any ideas on how to access SMART progmatically would you?
Thanks for the link!

Ok, I just installed XP SP1 on a co-worker's machine and she is now unable to switch identities in Outlook Express 6.
Has anyone XPerienced this? If so how did you fix it?
Thanks.
P.S. nothing at msdn.microsoft.com about it yet.

Just picked this up in the newsgroups:
There are currently two workarounds:
- Click on files/identities/manage identities and remove the checkmark in "Use this identity when starting a program".
For more information, see Q329084[^] - "You Cannot Switch Identities in Outlook Express After You Install Windows XP SP1"
- Before changing identity, Press F1. The Outlook Express "Help" window will open (and leave it running in the background). Now click on FILE > SWITCH IDENTITY and select your other identity. Outlook Express will ask the question "Do you wish to keep the same connection". Answer "YES". It will go to the identity you select.
