I have an ISA server that has been up and running great at home with a cable modem, till a few days ago. Web publishing,my Exchange and Terminal Services all work great thru it. Well, I rebuilt my wife's pc and when I went to install the Firewall Client I couldn't connect to my ISA server. Wasn't showing up on the network, DNS is resolving fine, but I could not connect to any shares. I could ping it fine and the server is functioning fine except for this issue. Well I narrowed it down to the DHCP Client Service not starting and the server wasn't showing up in my WINS database. I'm not sure what brought around this change. My netbios over TCP/Ip is disabled on my external NIC and enabled on my internal NIC, however it doesn't actually appear to be running even though Device Manager says its enabled. Also in Device Manager when I select the Show Hidden Devices view the Netbios over TCPIP shows a red mark on it. Any ideas what broke?

run "nbtstat -a COMPUTER_NAME_HERE" on the client machine and see what comes up. I'm having the same problem with my winMe client but it's not a big problem. It can't find any of the computers on the network.

Here's what I get when I run it on my winme machine(shakuras).
===========================
C:\WINDOWS>nbtstat -a shakuras

Lana # 0:
Node IpAddress: [192.168.0.2] Scope Id: []
===========================
and from the same machine

===========================
C:\WINDOWS>nbtstat -a antioch

Lana # 0:
Node IpAddress: [192.168.0.2] Scope Id: []

==================================

Antioch is a win95 client.

And again to my win2k server, Aiur.

=================================
C:\WINDOWS>nbtstat -a Aiur

..__MSBROWSE__.<01> GROUP Registered
LOGIN_NAME <03> UNIQUE Registered

MAC Address = 00-90-00-09-D2-B6
==============================

I dunno what gives. I can't even net time to any of the computers or net any_command.

C:\WINDOWS>net time \\aiur

Error 3545: You cannot start or stop the network from within an MS-DOS window.


=(

but it's not a biggie for me

Thanks HJB,
Here's what I did to get around it for now, well it appears my Netbios over TCPIP is totally disabled so I installed NetBEUI on the ISA server and my DC and my wife's pc, sure enough ISA popped right up and I was able to install the client. NetBEUI is not routable so no security hole and I only have 7 pc's on 100MB LAN so its not like it's gonna bog down my network.

if I install netbeui, is it ok to delete all other protocols [IPX/SPX and TCP/IP]?

Hi HJB,

Yes, you could do that, but you won't be able to connect to the ISA Server or the Internet :P

so, should I add netbeui and make it my default protocol while keeping tcp/ip installed? If worst comes to worst, I'm just gonna reformat and reinstall. =)

HJB, you have to have TCPIP, no ifs ands or buts. It is the Internet Protocol, Netbeui is just solving my problem for now of connecting to the ISA Server's share for client install.

Tom,
I have a netbios filter configured on my external NIC, is it possible something happened in my system to totally disable it on both interfaces? I'm starting to get Event ID 14148 errors, "Web Proxy failed to bind its socket to 'externalNIC' port 80" Any clues whats going on here?

Thanks, TJ

netbeui was a no go but it's cool. This computer's days are numbered. =)
------------------

reformatted, reinstalled, and now I can see the LAN. It seems to perform better than the previous installation, in terms of memory management.
