irritating IE issue

[mrbios]

right this happens on both IE6 and 7, we thought it could have been a conflict of ADMs between the IE6 and 7 ones but that doesnt seem to be the case

 

basicly when a user logs on and goes into internet explorer the page will sit there and not load, it appears that it doesnt see the proxy, we can then click stop and refresh and the page will load as it should

 

this happens on alot of machines but not all, its not related to the user as it can work on some machines but not on others with the same account

 

if anyone has encountered this issue we're at a loss for ideas on fixing it, please please please help!

[webman]

Are there any differences between the "HTTP 1.1" settings (Tools > Options > Advanced) on the affected and non-affected machines?

[mrbios]

ah ha, there different, http 1.1 through proxy wasnt ticked in advanced settings on our GPOs, the guy who made our IE7 policy obviously didnt notice the advanced tab under internet explorer maintainence

 

thank you webman, as soon as that replicates (multiple DCs and subnets grrr) ill post back if that works

[mrbios]

that didnt fix it

[Domino]

sounds a bit odd...there's not a limit on traffic through your proxy is there? as maybe its hanging and waiting for some bandwidth?

 

does it happen in firefox or opera?

[mrbios]

i cant test either of those as it happens to students and teachers only, those of us with non mandatory profiles seem to be fine

[webman]

Hmm. Check the event viewer - look out for IE branding GPO erorrs in particular. Not 100% sure though... :?

nothing in there, one error in system thats recurring to do with WINS which im looking into though

[plexer]

Have you run anything like a vbscript on the affected machine to show you the current proxy setup to make sure they have picked up the correct settings?

 

Group policy modelling to show what GPO's should be applied?

 

They're not trying to connect to t'internet via any dialup including msn are they?

IE6 and IE7 policies do work together without problems. IE7 simply has more options to tweak which are not applicable to IE6.

 

this happens on alot of machines but not all, its not related to the user as it can work on some machines but not on others with the same account

 

Chances are then, it'll be to do with where the computer objects are located in Active Directory. If a user can logon to computer A and the internet works but not computer B then it isn't a user or profile issue.

 

I would compare where good and not working machines are in your Active Directory structure. I am presuming network connectivity is ok and that you can access your network drives and printers for example.

 

A conflict can happen if a computer is in an OU named "Computers", but the user is in an OU named "Pupils" for example.

 

The easiest way to get around this (for example), is to create an OU called "Curriculum" then two sub OU's Computers and Pupils. You would set the policies on Curriculum and the sub OU's would inherit the policies set. I hope this makes sense.

[mrbios]

both machines are in the same OU on the same subnet, even sat next to each other physicly, network connectivity is fine, all drives and printers mapped etc

[Michael]

So network connectivity is fine by the sounds of things. I would try deleting all locally cached profiles in C:\Documents and Settings\ or even better, specify this policy -

 

Computer Config > Admin Templates > System > User Profiles

 

Enable - 'Delete cached copies of roaming profiles'

 

Now logon to a problem machine as an administrator and at the run menu type: gpupdate /force

 

Now reboot the workstation and see what happens.

[mrbios]

tried deleting all the cached profiles before and that didnt work, ive also got "delete cached copies" enabled all the time

 

[kentt]

Forgive me but, on the PC concerned have you tried flushing the DNS cache (@ command prompt: ipconfig /flushdns).

[mrbios]

yea we tried that

 

We managed to fix the symtom but not the cause though, changing the homepage to an intranet page with a link to an internet page within it fixes it, the problem only occurs when we direct users homepage to be a page out on the internet

[webman]

That's odd.

 

Do the machines have a default gateway?

[mrbios]

yep

[webman]

What about proxy settings and the like, is it set to automatically detect or anything?

[Joanne]

have you tried typing this in run:

 

regsvr32 actxprxy.dll

 

and it does something... which might fix it!

[mrbios]

tell you what, have a gander at this webman and see if you can see anything ive done wrong in there, this was completely remade yesterday by me as the old one had a few corrupt ADMs

^ dont know if that file host is any good, thats a report of our policy (dont think theres any security risk behind this but tell me if there is and ill remove it)

 

and ill test that one out joanne, cheers

It sounds like a problem we had with authenticating to the proxy server. In IE6 some people/PCs occasionally get an error:

 

Error Code: 403 Forbidden. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)

 

on the first page they load up. When they refresh the page it works. Firefox doesn't have the problem. From the monitoring I did on our ISA server I think it was caused by the page initially being requested directly, then subsequently being requested properly i.e. via the proxy server.

 

You may be able to do some troubleshooting from your proxy server end.
