Internet Explorer keeps on saying page cannot be displayed.


when I am browsing I keep getting page cannot be displayed. It is really happening whenever I try to log into any sites. Especially if they use SSL. I use a proxy at work and get access to most things but at home when using my adsl broadband I am having real problems. (Its a personal laptop I take to and from work). I know its not the broadband as it works fine with my desktop computer. The problems are just on my laptop.

I have ran Ad-aware spybot and registry mechanic. But none of these things are working. I also cannot connect to messenger or get windows critical updates. The error messages usually tell me to edit my proxy settings, but at home I disable my proxy in IE settings.

Below is a log from HyjackThis program just incase you see anything evil on my computer.

Hi pgilfeather,

Have you confirmed that you are pulling a DHCP address on the laptop?  Also confirm that you have DNS servers.

I went into my tcpip settings and it is set to DHCP. I did an ipconfig in dos and confirmed that I was connected with a dynamic ip.

Also confirm that you have DNS servers. What do you mean by this exactly? Sorry, I'm not expert on networking, I need taken by the hand on this one.

When you are at home, do you turn off the proxy settings?  

I have the same intermittent problem.  At work, we use a proxy .pac file but of course at home, no proxy.  

So, the fix is as follows:

When at home: In IE, Tools, Internet Options, Connections Tab, LAN Settings, uncheck whatever is checked.
When at work: Put a check mark in the check box that you previously unchecked.
" The error messages usually tell me to edit my proxy settings, but at home I disable my proxy in IE settings." - Are you sure that ADSL provider have no obligatory proxy? Does your desktop surf with the same settings as laptop?

Open a command prompt from start, run, cmd and then type in nslookup and see if it returns an address.  If not, you will need to add DNS servers manually.
The other thing might be that you need to tell the system not to use a proxy.  To do this, open IE and then click tools, internet options, connections, LAN settings and uncheck all three boxes.  Click OK and OK and close the browser.  Re-Open the browser and see if you can get out.
your hijack log looks ok
when you can't fetch the page, can you ping the site?
how about tracert?

nslookup typed this in and it came back with a yahoo web address and a number of ip addresses. Yes I always go into connections tab, LAN settings and untick the use proxy server tickbox.

I am trying to get onto the site I can access every part of this site but cannot login to check my account. I also cannot log into hotmail. The page cannot be displayed error is instant. No delay whatsoever.


Do you surf successfully but have trouble with logons only?....Exactly!!!

Are you blocking cookies?
No, Im not blocking cookies........... set to "Accept All Cookies"

Running IE or Mozilla or Firefox?

You hit the nail on the head. I am sorry for not being very clear. I can surf ok, its just when I try to either logon to certain sites or encounter a SSL site that it throws me out.

Sorry, hope this makes more sense.

I don't think it's MTU problem if  pgilfeather doesn't connect through the desktop...

Maybe ZoneAlarm ("C:\Program Files\Zone Labs\ZoneAlarm\zlclient.exe" was mentioned) is a cause of problem if it is set only for corporate proxy port and does not allow traffic to/from 8080?
Here is very simple solution to ur problem:

If you are using Windows XP and u know from when(approx) this problem started. Do this:

Go to programs -> accessories -> Restore. Select the first option and then select the date to which you want restore.
System comes back to original settings and the login prob u are facing will solve. Please read instructions on screen while restoring.

I m doing same for many novice users.

I would advise against removing all the rules.... most of them would have been put in by default, and for good reason, you could easily open up a hole for someone to get in, intentionally or not.  Doing that could easily cause more problems.   If you can't find the rule(s) that applies to tho SSL connection, I will be more than happy to help you locate it.

default rules? I(personal opinion) don't think so, all the rules get created as soons as the system encountered that a rule does not exist. Therefore any new connection to or from your system will BLOCKED and a rule created and displayed on the screen until such time that you enable this rule. The reason why I suggested that he delete the rules is because then he will be able to properly test if that is where the problem lies. As for him being being vulnerable, it all depends on what rules he enables, and the rule of thumb should be...if you don't know what it is then block it. Maybe to be safe, either export the rules before you delete them...of course you should always do a backup before any system/security changes :). You could also delete a rule that you know about, and then see if the system re-creates the rule when you try to access that resource again.
pgifeather, did you instlall xp's service pack 2?  to test if that the issue, you can turn its security off as a test by

controll pannel
right click on "security manager" or what ever its called, i forget unless its in front of me
select stop service.

you also may be hyjacked past what your spyware removers can do, but i kinda doubt it.

how about what CSharp said???  that diffrent browser thing..



If you are talking about program control rules, then what you suggest would be fine.  Sorry about that.

No problem, what are forums if not for asking questions? :)
HI first thing to do is check for valid IP address and ... then check net work connection through LAN settings make sure nothing is checked....
Then launch then default gateway you pulled in Ie or telnet into nterface and then run set-up..... You might have to reset the modem/router depeding on your connection...

When Done post back you default gateway if it is a local C....
