I am connected to the Internet but I can't use any Inet apps

I have Win2K on my PC - I have a DSL connection (QWest via a CISCO 675 router) - I am using an independent ISP – yesterday I was telecommuting at home – all was fine.  I decided to upgrade my virus sw to the new version of McAfee – all still working well.  I also decided to upgrade my Windows Media Player to the latest version.  Next thing I know is that I am unable to make a connection back into my work network, my browsers no longer work, and I can not access my ISP based Email.  

I call QWest they tell my that my CISCO 675 is training properly and I am connected to the Internet.  I call my ISP and he has me do the following from a command line:

ipconfig /flushdns

and then he has me change my TCP/IP from DHCP to a static situation (IP address, Subnet, and DNS) – and then he has me ping the CISCO and the DNS his DNS server from the command line – I could ping both.  However, I could not get any browser or my Email to work.  He has me try to FTP the DNS server and I get a socket error.

He has me uninstall the new McAfee and turn off any firewall apps – which I do – no joy.

I scan the hard drive – and then defrag it – I have uninstalled my TCP/IP and my client for Micro$oft networks and try again – no joy…

Any ideas ??  I remember that there was a way to flush the registry in Windows 95 with out installing any thing else is that an option?

Thanks

you need to isolate the problem.  Can you ping:

127.0.0.1
your netbios name
another host on your same subnet
your gateway
your dns server

Any errors in your event logs?

I can ping the CISCO router that we (ISP & I) set up with the static IP address of 10.0.0.254 (I am doing this from memory - the address may not be exact - I don't have email at home so I am trying to do this from work) - and we put in his DNS IP address - I can ping "any" IP address - but, if I try to use my FTP app, my email, browser, anything that uses a port - no joy...

I can only ping things...

Ok we're getting closer, it appears you have local connectivity.   Can you ping public addresses by name like for instance, his dns server i.e.:  ns1.isp.com

can you browse using IP's only?   It's starting to sound like a dns issue.

I have not tried pinging DNS addresses instead of IP addresses.

However, I have uninstalled all of the network related components (TCP/IP, Client for Micro$oft Networks, etc.) and rebooted and then reloaded those.  That didn't work either...

I will try pinging DNS addresses tonight when I get home.

ping www.cisco.com, it might return 198.133.219.25

then try to browse to that ip and see what happens.

If that works, try setting your dns to something else like 206.196.128.1,  thats a qwest dns server if I remember correctly.

I have tried some thing similar to this - I have pinged the IP address of my ISPs DNS Server - and it worked fine - but, I couldn't browse to it (IP or DNS address).

I use QWEST for DSL - but, not for and ISP - but, I will try anything you suggest at this point...

Have you given any thoughts to a corrupt registry?

Thanks,

  Try the previous step please.  You probably wouldn't be able to browse to a dns server because dns is probably all it does.  We need to test name resolution. the 206 address is a public server so you should be able to use it,at least temporarily.  
As for your registry,  it's not quite so easy as it was in 98.   Have a known good backup from before you were having issues?

B,

Okay, I ended up camping out on hold last night and finally talked to a tech at Dell.  

First off all, I was not able to ping the DNS address you provided.

Back to the story, I told my tell of woe and pain to the Dell tech - he had me go into the C:\WINNT\inf folder and right click on the ie.inf file and then click install - had to pop my Win2K CD-ROM in and it went through its happening (Dell's reason a lot of things are tied to IE and being properly installed) -

Next step; was to go into the registry and export the Winsock & Winsock2 files to my desktop and then delete them.  Reboot the PC and then go in and install a different protocol (we used NetBEUI) and then take the check mark off of the TCP/IP protocol in the Network properties (Dell's reason - that sometimes if you try to uninstall a protocol with out having another installed you won't get a clean deletion) - okay - rebooted the PC again.

Then went into the Network properties and uninstalled the TCP/IP protocol completely and the NetBEUI completely - rebooted again.

Then he had me re-install the TCP/IP protocol and reboot - guess what?  Everything was working again.  So, before I let him get off of the phone - I asked him if I could reinstall the newest version of McAfee virus 6.02 something like that.  I did that and rebooted and now I can only use my email - my Internet connections via the browser are not working any longer.

I have uninstalled McAfee and redid the previous steps - all I have is email access -

NO browser access - I can ping IP and DNS addresses now though...

Any ideas on this?

Thanks,

When you open your TCP/IP properties for your adapter and use the ADVANCED tab do you have TCP/IP filtering set to allow all TCP ports, UDP Ports and IP Protocols to ALLOW.

All - it turned out to be a problem introduced by McAfee's latest virus software - I downloaded it and installed it prior to all of these problems starting - Dell walked me through a series of steps that removed the Winsock and Winsock2 folders from the registry.  That fixed the problem and I asked the Dell tech if I could re-install the McAfee and a similar problem started again.  To make a long story short I ended up re-installing Win2K and went back to the older version of McAfee - I have not had any problems since then...

I contacted McAfee and they refunded my money...

Since Birdski gave me the most time - even though he/we didn't solve the problem - I appreciate his efforts...

Thanks to those who provided time and knowledge...
