I'm not sure if I can accurately describe this problem, but I'll try:

A user has come to me with a Windows 2000 laptop, Service Pack 3.  It is network connectively to our LAN, as well as the ability to browse out through our firewall to web and ftp sites but only if Internet Explorer is used to do so.

If I try to use any other program such as the CMD prompt "ftp" and "telnet," or in specific case Dreamweaver's Site Manager FTP to connect to a remote location, I get errors such as:


FTP:  ftp: connect:Host is unreachable *or* Connection timed out
Telnet:  Could not open a connect to host on port 23 : Connect failed
Dreamweaver:  Could not connect, the connection to host failed.


There is no personal firewall installed on this PC;  there is in fact a firewall client installed to allow it to be granted full access through our ISA server (this works on all other machines).  I have uninstalled and reinstalled TCP/IP from the machine.  I have laid SP3 back down on the machine.

Basically, it seems to me like ports are failing to be opened unless it is done through IE (which of course is configured within LAN Connection Settings to use the ISA server as a firewall) via http:// or ftp:// usage .  Otherwise, all other programs which require external access fail.  What could be causing this issue, and how can it be resolved?

The client only allows you to get through hole sthat exist or are opened, it does not provide inlimited access to telnet or ftp, especially if those ports are blocked.  (Those ports are blocked by default for most ISA Security configurations.)  I bet if you ping www.microsoft.com you will get an IP resolved but it will time out.

I'm sorry, I should have been clearer when I said "this works on all other machines."  We have currently configured all users with Microsoft Firewall Client installed to belong to an 'Firewall Users' NT group.  This group has then been added as a member of a Protocol Group within ISA which allows essentially all IP traffic, including all major protocols.

So you see, this should be allowing them to manipulate FTP and other IP traffic at the very least.

If you have enabled and updated the client, then there is a communication issue or another problem.  Uninstall and re-install the client?  You may even need to remove this workstation from the domain and rejoin it to the domain.

Unfortunately, this doesn't seem to have corrected the problem either.  In fact, the re-installation of the Firewall Client brought me to a System Shutdown message upon login, informing me that services.exe terminated unexpectedly with an error code 128.  Looks like this baby might need a spring cleaning.....?

Even though my problem was not technically 'solved' you did offer a few good suggestions MSGeek and I appreciate it.  I think I have no choice but to reformat this machine, as it seems it might be on the brink of having major issues.

I agree with you, sometimes it is not worth chasing ghosts.
