help! no http connection, but other protocols okay

[gokatgo]

I have three computers on a network -- one of the three has lost the
ability to connect to web pages via the http protocol. Ping, email,
chat, ftp, localhost and https just fine, but I get no connection for
http. (I've tried Firefox and IE7, neither work.)

The problem started yesterday about the same time I installed a Cisco
VPN client and could not get it properly configured to connect to a
network -- I may have inadvertently changed some setting in trying to
get the VPN client to work. We also ran a bunch of Windows updates
yesterday morning, and uninstalled a bunch of garbage from the machine
sometime during the day. Nothing like mucking everything up all at
once.

I have...

uninstalled the VPN client
reset the router
checked the firewall (including disabling it altogether)
run netsh winsock reset
searched for spyware, viruses, etc
checked the proxy settings, security settings etc in IE (but that
wouldn't explain the Firefox probem.)

I was considering a system restore, but the only restore point seems
to be from yesterday evening after the problem started -- which is
strange in itself.

Any advice would be appreciated.

1- try these:
a- Click Start >> Double click Control Panel.
b- In the Control panel Double click Networking and Internet Connections.
c- On the Networking and Internet Connections Double click Internet
Options.
d- On the IE Properties window click on Advanced Tab and scroll down
under this Option and uncheck these boxes:
[&] Browsing
[ ] Enable Third Party Browser extension Uncheck this

Then Option and check these boxes:
[&] Security
[ ] Use SSL 2.0
[ ] Use SSL 3.0
[ ] Use TLS 1.0

Another Click on Content and click on [Certificates....] and try to renew
or see what Certificate you have there.
Click [OK] to confirm your Changes and close the IE properties Reboot and
see if you could access http://.

2- If still no joy try this:
Open a run command and type:
regsvr32 softpub.dll click [ok]
regsvr32 initpki.dll click [ok]
regsvr32 softpub.dll
regsvr32 Wintrust.dll
regsvr32 Mssip32.dll
regsvr32 Initpki.dll
regsvr32 Msjava.dll
regsvr32 Gpkcsp.dll
regsvr32 Sccbase.dll
regsvr32 Slbcsp.dll
regsvr32 Urlmon.dll
regsvr32 Cryptdlg.dll
regsvr32 Dssenh.dll
regsvr32 Rsaenh.dll
3- If all Fail try this command :
sfc /scannow get your XP CD handy to insert it if been asked so by the
System.
Please perform one sttep (1,2,3) at a time and reboot your machine and see if
that resolved the issue.

=> Another method:
Open a run command and type in:
regedit click [OK] and locate these keys:
[-]HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\URL\DefaultPrefix =
[ab] (Default) REG_SZ http://

[-]HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\URL\Prefixes=

[ab] ftp REG_SZ ftp://
[ab] gopher REG_SZ gopher://
[ab] home REG_SZ http://
[ab] mosaic REG_SZ http://
[ab] WWW REG_SZ http://

NOTE: I noticed from experience that sometimes some left behind debris from
incompletely uninstall application can cause this issue, so run Disk CleanUp,
look in the Add/Remove for any old Apps didn't uninstall completely.
Open the Windows Explorer and locate this path:
C:\Program Files\Applications or old Empty for uninstalled application still
in the directories.
HTH.
Please let us know.

Thanks. I tried everything you suggested, but still no http. Any other
ideas?

Here's some new info -- if I boot into safe mode (with network access)
http works fine. So something must be loading at startup when not in
safe mode? Is there a way to trace what loads in safe mode and what
doesn't?

Try this:
Download the winsockfixer from here:
http://www.nasstec.co.uk/tools.html

Or you can perform a system restore to an earlier date?.
Update your Java version and compare the setting on all computers for the IE
settings, I agree with you it does not explain the Fox lose of hair LOL.

IPConfig /FlushDNS [Press Enter key]

NETSH

Click Start, Run, type:

netsh winsock reset

Restart the system

You can also try this software download from a working machine:

I bet as I mentioned in my earlier post a dead body from an old uninstall
app?.
Download these tools to see the running processes in real-time and you
can search them to make sure they are Legit.

I'm just about ready to give up and reinstall the OS on a clean HD.

Configuring Windows to boot into a clean state (but not in safe mode)
did not work. I compared processes between the safe mode where http
works and normal mode where it doesn't, and can get normal mode down
to a similar set of processes, but http won't work.

I think the problem might be tied to an upgrade to Acrobat Reader that
installed Photo Album Starter Kit. I uninstalled Photo Album, and
deleted the stray files leftover after the uninstall, but msconfig
shows apdproxy.exe in my startup items, and lists the location as C:
\Program Files\Adobe\Photoshop Album Starter Edition\3.0\Apps
\apdproxy.exe, but that folder no longer exists. When I remove the
item from startup and reboot, it remains in the list.

Does that suggest a registry entry that needs to be edited? I haven't
tried uninstalling Acrobat Reader yet... maybe that's the next step.

Thanks again for all your help. I really appreciate it.

Hi,

If you used the AutoRun Utility, you can delete it from under either :
Logon Tab, Internet Expolrer Tab or in the Registry:
Open a run command and type in:
regedit.exe click [OK]
[-] HKEY_LOCAL MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\RUN =

Open a run command and type in:
regedit.exe click [OK]
[-] HKEY_LOCAL MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\RUNONCE =

Open a run command and type in:
regedit.exe click [OK]
[-] HKEY_LOCAL MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENT
VERSION\RunServicesOnce= Delete from here, Right Pane/Window.
Run the Disk Cleanup, then run this command:
sfc /scannow click [OK] you will need your XP CD handy.
HTH.
