Problem accessing internet

[esung]

This is a weird problem on my friend's computer , here's the symptom. The computer can not access the net with any applications. IE, Mozilla, Outlook.. I've tried different type of connections (all proven good with other computers). DSL and dialups both.

However, I can ping the machines on the net, and tracert works fine. and the domain names resolves correctly in both cases. but any applications I tried just couldn't connect. (not errors code given). Only when I tried using ftp it gives me an error code 10047. (can't create socket service I think).

I also tried uninstall and reinstall the network drivers and TCP/IP protocols, and the problem remains.

I think the problem exists because my friend installed some type of web acclerator, and after uninstall, it might have some other stuff left in the system, either some files and/or some registry settings that's not completely replaced/removed. He couldn't remember what's the program installed, and I couldn't find out anything wrong with his
computer (it's almost brand new).

Does anyone has any ideas what's wrong? thanx a lot.

I would see if your winsock is damaged. If you have Win9x, go to dos prompt and type winipcfg, if you get a error, let me know what it is. If you have win2k, type ipconfig /all and tell me if you get a error.

If you don't get any errors like that, I would recommend a backup, flush, and restore. You could spend days trying to figure it out and if you can just restore the system and be done with it, then I would do so. 🙂

Just my 2 cents.

Fixing TCP stacks in Win* --

-Back up your registry.
-Delete ALL entries under Network Properties (ethernet adapter, protocols,
etc)
-Delete the following keys from your registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\AFVXD
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\DHCP
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\Winsock2
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\WinSock2
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Authentication\SMM_Files
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\netTrans\000n
-If Win.com exists outside of your windows directory, delete it.
-Reboot -
Allow redetection and reinstallation of network card and protocol(s)
-Reboot

-If issues continue, boot into DOS with cdrom
-----Navigate to windows\system32
-----Use the following commands: ren vip.386 vip.old ren vtcp.386 vtcp.old ren vtdi.386 vtdi.old ren vudp.386 vudp.old ren vdhcp.386 vdhcp.old ren vnbt.386 vnbt.old
-----Reboot into Windows
-----Extract the files from your Windows cab files (from a DOS prompt) using the following format: extract /a a:\win95_02.cab unidrv.dll /l c:\windows\system where "a:\win98_02.cab" is replaced by the first cab file listed and where "unidrv.dll" is replaced by every file renamed above
-----Reboot once more


Similar instructions apply to Windows2000 (ignore what you can't do and of course, replacing files from .cab, which usually isn't needed in any case).

Thanx Ladi!

I think what made the difference is the removal of registry.. now my friend will know that never install those web accelerator (he doesn't need it anyway.. 😀)
