I have a very annoying problem with my PC. Intermitently, I can't access my mail and web server while the server itself actually is up and can be accessed with any other PC and Blackberry.
Out of my frustration, I had reformat my PC and reinstall the OS from the fresh but yet the problem still persists.When the server unaccessible, Ping will get message "Could not find host" and IE will give the usual blank space/check connection error.
It happens on my email and web server (both host under Linux/Apache) system.But strangely, sometimes after a while (few hours), it started to reconnect again.
I have done : ipconfig/flushdns and reformat the whole system, ran adware, malware, antvirus can't find any problem.
Other than my mail/web server, I can connect with any other website on my PC with no proble,, so the problem ONLY in connecting with my specific server.Please anybody help me.....

On your workstation go Start and in the Run line type cmd then hit enter.
You are now in a black box.
Type ipconfig /all and hit enter.
It will look something like this [mine is wireless vs wired]

You have a name resolution problem
Computers talk in ip addresses but we talk in names like My Home PC. Name resolution is where the machines change name to ip address and back again.
You are pointed to the ISP dns server. Only if you had a local dns server, and it knew of your local Apache servers name and ip, would you be able to resolve name to ip or visa versa.
Before I bore you with further explaination I would suggest you add an entry to your hosts file on the workstation that lists your Apache server name and ip.
Here is a link.
http://kickenhardware.net/forum/sho...In this example they show how to block a domain name. In your case you want to add your apache ip and name in the format required.
Once you edit and save you have to reboot to become active.

OK. I got it, now I have added 120.50.35.152 and my domain name on the host file. Hope it will fix it.
Will keep you updated....
Thanks a lot.

You were to add the
ip address and host name of the apache server
not your domain name.I was under the impression you were running your own internal web/mail server. That ip doesn't look right for a publically and privately accessed server.

Actually I am running co-hosting service in Singapore. After I checked on whois, I got this.
Name Server: NS1.LINUXHOSTINGSINGAPORE.COM (has 82 domains)
Name Server: NS2.LINUXHOSTINGSINGAPORE.COM (has 82 domains)Server Type: Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635
IP Address: 120.50.35.152What should I write?

120.50.35.152 is the correct ip to linuxhostingsingapore.com
so the hosts entry would be
120.50.35.152 [space] www.linuxhostingsingapore.comThough I now suspect its your connection not name resolution since this is not a local hosted solution but via the internet.
This thought is supported by the fact you couldn't get to the link I provided.
It is the connection between you and the hosting that is the issue.

I was having connection problem yesterday thru my other ISP but now the link can be opened.
Now I have added 120.50.35.152 [space] www.linuxhostingsingapore.com on the Host file.Let see if this will solve the problem.... keep my fingers cross
