Hi everyone,
We're having a very strange networking problem with one of our servers today, and I'm totally clueless about it, I was just hoping that some of you might have an idea on what is happening.
So we have this Windows 2003 server with a single NIC and several IP addresses assigned to it. One major website is using one IP address (A), and several small sites share another IP address (B). What happened this morning (and yesterday too) is that we cannot access the HTTP server, nor the POP3 and SMTP server at the IP B, but the website as well as the mail server at IP A works just fine. What is more confusing, we can ping both IPs without a problem.
I asked some of my friends here in Slovakia, UK and US to test both IPs, and all of them could access websites at both IPs, except for one of them who had the same problem as we had, but couldn't even ping IP B. They have a different ISP, and it started to work for them after a few minutes. But we're still having the same problem.
Does anyone have any idea what can be causing this? I'm absolutely clueless. Is it something with our ISP, or with the hosting company that hosts our servers? I don't know what to search for or what to check. It is probably not a problem with IIS as nothing responded on IP B, not even remote desktop or MailEnable mail server.
I forgot to mention that a similar thing happened yesterday, but everything went back to normal after restarting the server.

I used to have the similar problem like you when I was working at my workplace. You should turn off your server (IP. B). After turn it off, try to ping to its IP address. If it is reply it mean that some computer has changed its IP address that duplicate with the server. If it is not reply it might came from the other problem. Try to do it, if it is a conflict IP turn off the server and use ping command with -a (ex: ping -a ...) to show the host name of an IP address and try to locate it on your next work.
On the other hand if your computer still have a problem and display any message box, record it and search in google or post it in here.
The above description just a small peice of experience that I faced with my old workplace. The problem might occure by difference issue.

Just a few ideas here...
When you can't reach the site at B, what message do you receive? Server not Found, or Page not Found? In the TCP/IP settings for the NIC is the box "Register this connection's addresses with DNS" selected? You might want to add entries to your HOSTS file for each site as a test, then have your testers try again. Also, have them try reaching the site using a URL containing the IP address instead of the normal URL: http://207.166.95.74/MySite/default.htm instead of http://www.mydomain.com/MySite/default.htm.
On Windows 2003 using Active Directory is not optional, IIRC, as it is in Win2K. Check to see that all of your sites are properly registered there, as well. I haven't a clue how to do so, since I've never played with it, but give it a look.

Hi all,
I'm hopping that someone can help me with this:
I've been trying for about 2h to delete a *@#!$%# directory on a XP Pro machine and all I get is "There was an error accessing the device". I was able to delete all its contents but can't delete it, rename it, change its attributes or anything.
I've already did a boot-time chkdsk who found no problems with the disk and am running out of options.
Does anyone know how to solve this and get rid of this directory?
TIA

Try to run your computer safe mode and delete the direcotry whether from DOS or from windows explorer. It it imposibile, try to scan your hard disk for bad sector. I also have the problem with my external hard disk too. Some folder it could not delete because it locate on the bad sector.

Thanks for your reply. It worked after my 4th or 5th startup chkdsk. (I haven't the faintest idea why the first ones didn't do any good).

(please excuse the long post - hopefully the details are helpful)
Platform: XP Professional
Summary: I am looking for a way to automatically log time spent in various applications. My intuition directs me to identify various trappable Windows’ events and API hooks to get this information. I am open to any and all advice. See business problem below if you want more details on the problem to be solved.
I will be happy to use a preexisting application or if necessary I can create my own. I have my own application tools and can create the necessary database and code with proper APIs to populate it, however I need to trap the Windows Events (or have those events call the APIs). Off the top of my head, I imagine I will need to trap the following for the various applications I use in the course of a day (my code would add a date/time stamp):
1) Windows start time
2) Application start and end. (Application name and startup parameters)
3) Application switches (Application name for switch from app and switch to app) – switch could be either by mouse or <alt>-<tab>.
4) Idle time begin (could be same as screen saver activation) – need app with focus when “idle timed out”
5) Idle time end (need app with focus)
6) Many others I probably forgot
7) Windows log off time
Do any such events exist that are trappable? Will the Windows SDK help (is there only one or do multiple flavors exist)?
Alternatively, I imagine I could use spyware or a key logger (to spy on myself), but would like not to for a few reasons. First, distilling all that information will likely be as much work (or more) than my current manual effort to record the information. Second, I do not want passwords, credit card numbers, etc sitting around in log files.
Business Problem: I am in the software services business (4GL development in the manufacturing sector) and have always tried to keep detailed documentation of the work performed including analysis, communication, development, project managment, etc. This effort has served two very good purposes. First it aids my memory significantly when problems reoccur or people say “remember …?” – my memory is not nearly as good as I would like it to be. Second, it is the foundation for documenting work performed when invoices are submitted. This latter point has been invaluable as well – people see what they are paying for which leads to far less questions and less “sticker shock” especially when they made a multitude of additional requests.
Thank you.

What's the filename extension? What program(s) create/read them? Try using Google to search for file formats using the same extension. There are several sites on the Internet that publish the internal structure of various file formats; you might just get lucky!

Hi, I used windows xp professional. Because everytime that my computer startup and log on is to slow, I decide to choose hibernate everytime that I want to shutdown my computer. When I continue to work, it start again and it is faster than I turn on the machine from shutdown. If I still continue to use hibernate forever, is it have any disadvantage to my system? (Especially hard disk drive).

for sure all your ram memory will be stored in the harddisk then loaded agian, but it shouldn't couse any harm to the harddisk!

Hallo,
I am writing an installer, which should also configure a toolbar on the taskbar. This toolbar should show the contens of the directory "D:\Log". I know that this can be easily done by using the mouse, right click on the taskbar and select "Toolbars -> New toolbar..." and choosing the directory "D:\Log" from the dialog box. But how can I do this programmatically using VC++? Or can VBScript also do this? (Other languages are no option in this project.)
Thanks,

Hi, I have 5 computer in my house, I want to connect network to use a library to research. But I still have a problem while choosing the hub/switch. I choose 8 port device but I still could not figure out that I should choose hub or switch? I just know that 8 port switch is more expensive than 8 port hub. But I don't know which situation that I should choose hub or switch. Could anyone give me some suggestion to choose between hub or switch to connect network to learn at my home?

The difference between hub/switch:
Hub: Data recieved on any port is broadcasted to all ports in a hub
Switch: Data recieved in a port is sent only to the spefic port it is destined to.
In a switch the speed could be better as data is sent only to the needed ports and not to all ports.
For a network in a house, with less traffic a Hub should do. With just 5 computers and application like yours there would be no difference. So i would suggest you could just go with a Hub.

Thank you very much for your comment! I will buy hub to set a lab at my house.

there would no advantage of using hub or switch at a small network level of yours but if u are plaaning to use hub on price basis then u should go for a switch as there is not big diffrence in switch and hub .
the technical diffrence in hub and switch is , switch has a repeater while there is no repeater in hub , so switch has a advantage of fast data transmission , as the data in such small in not larce as in case of big and vast networks like 100- or more pcs. the switch basically smothens your network , but i would prefer u switch as there no price diffrence in it , so if u want increase number of pc u can have better hardware support support.

Hey,
Just recently loging off or shuting down my computer has starting taking a very long time. I am running Win2k and the hangup occurs when the box pops up that says "Saving Settings..." It takes anywhere from three to five minutes to get past this.
Any ideas on why this takes so long?
-Thanks
Mark
