Okay I have wasted about 30 hours on this now.
I have a windows 2003 server in my office which is running a Remote Access Service.
I can connect to it with one PC but not the other. Buth PCs are XPPro SP2.

The one that cannot connect has Norton AntiVirus 2005 installed but I
have disabled the worm protection.

I have disabled the windows firewall.

I don't have any other firewalls.

I have read every and I mean every other post on this topic in every
newsgroup you can imagine.
Keep in mind, I can connect using one PC bot not the other, so the
server is NOT the issue. Both PCs are behind the same router, I get
the same issue when I take out the router, even when I am within the
same network as the 2003 server. I am using the same username and
password on both pcs.

I use the "Create new connection wizard" and give it the same info as
on the PC that does work.
When I connect, it says "verifying username password" but then gives me the 619. 
Now I know that seems like there is a connection, but the log on the
server doesn't show anything at all.

Here are some other info on the pc that cannot connect:

IBM Thinkpad T43p
NIC: Broadcom NetXtreme Gigabit Ethernet (Driver 8.22.1.0)
Other things installed:
Cisco VPN Client Version 4.6.04.0043 (this one does work)
Norton AntiVirus 2005 (Worm protection disabled)


The funny thing is that the PC that does work has both Norton Worm
protection and Windows Firewall turned on. I tried this on the one
that doesn't work still nothing.

Also after every change I have restarted the PC for good measure so that's not it.

Thank you

Clarification of Question by t_r-ga on 22 Mar 2006 17:22 PST

An acceptable answer will be one that fixes this problem or leads to
it getting fixed.

Step 1: Restart your computer. If you still have the error, go onto step 2

Step 2: Delete your connection.
To delete your connection, right-click the mouse button, and
left-click on Delete. Then reinstall according to the XP directions.
If this does not correct the error, go onto step 3

Step 3: You now need to remove the modem/network card.
Go to Control Panel, Phone and Modems, Modems tab. Highlight the
modem, and click on Remove. After which, close everything, restart
your computer and Windows will reinstall the modem/network card for
you.

This is a 'bug' in the Windows XP operating system. It may or may not occur. 

If that doesn't work I'm not sure. have you tried microsofts support
forum? they are usually pretty good.

Tried all of the above with the exception of removing network card and readding.
I am terrified of losing the current Cisco VPN that is installed and
ruining that as well.
Is there any MS fix that could possibly fix this problem? I have seen
dozens of people with this same issue and no one seems to be able to
fix it.

The problem is Norton AntiVirus 2005, even disabled it blocks ports.
Uninstall it completly, restart, when loaded up click start, run
type in msconfig goto startup and check it has gone.
Now your VPN software should work.

I had the same issue and thats how I resolved it, I did install Norton
again then after much setting searching found a setting that fixed it
but it was a while ago so can't remember where in Norton.

Is the Cisco VPN Firewall running? If it is, turn off the "Stateful
Firwall". If you are behind a router/hardware-firewall this might also
be the problem. Have a look at the following link and see if one of
the options help you:

Okay I can't thank you enough.
I noticed that in my services there was Cisco VPN service running even
though I had never started the client itself. Now I can connect with
Norton and Windows Firewall both running. I have noticed people are
very quick to blame the antivirus softwares for everything. Thank you
so very much. This ends an entire month of turmoil.
