Hi experts,

I have a problem accessing internet (web and email) through dial-up.

The laptop I using can connect to my ISP with dial-up with no problem. But I IE does not access web page after trying opening pages for a while. Email is also not working. It seems IE getting access something else rather than dial-up line.

My laptop has a fixed IP address but not for internet access. IE->tools->internet option->LAN setting is not used at all. What I can suspect is I tested proxy to share the modem but now I (think) I put back every setting for dial-up access.

Whatelse blocking my laptop from dial-up internet access. I use XP Pro SP2.

Please advise.

1) Are you using any firewall product?
2) Try the following:

2a) open a command prompt by typing cmd.exe on the Start/Run dialog box.
2b) type nslookup and press enter
2c) type some known web site, like www.microsoft.com. Do you get some response? You should receive an ip address for the microsoft's site. In this case, the response should be something like that:

Non-authoritative answer:
Name:    lb1.www.ms.akadns.net
Addresses:  207.46.225.60, 207.46.19.30, 207.46.19.60, 207.46.20.30
          207.46.20.60, 207.46.198.30, 207.46.198.60, 207.46.199.30
Aliases:  www.microsoft.com, toggle.www.ms.akadns.net
          g.www.ms.akadns.net

Make those tests and tell us about the results.

Since you mentioned that your LAN connection is set with static IP, I suspect your DUN is using the DNS settings from the LAN TCP/IP settings. When connected with your dial-up connection to your ISP, verify (run IPCONFIG /ALL) if your DNS settings is right.

Good luck...

Thanks for reply

I turned off the fire wall. Remove fixed IP address. Make sure no fixed DNS seting. Then did ipconfig and nslookup.

While trying these commands, suddenly IE start loading page, but really really slow. I just wondering what is causing this...??

Here is the result of command

C:\Documents and Settings\equitv>ipconfig /all

Well, it seems that your firewall was blocking something.

Besides, your primary DNS is timing out. It had timed out here with me too, but answers eventually.

I think you have two problems. Your firewall maybe blocking your access and your ISP has some problem with its connection reliability.

Configuring network clients can be a chore, especially if there are a large number of them or a lot of itinerant users.  DHCP dynamically manages this process, much to the relief of users and administrators alike!
