I have lost connection to my LAN and the internet on my server running Win NT4 Sever Back Office. It shows the NIC as working but I cannot get out. I am running not firewall or AV.I have Spybot and Adaware.
I am trying to set this up to host a web server for the kids web pages.

HP LC3 NetServer
Dual P-III 500mhz
1 gb RAM ECC
3-18gb SCSI


Was working until I tried to get the IIS 3.0 configured. This is new territory for me. I am also trying to port foward HTTP via port 8080.

Acklan: Nobody else decided to take a crack at this, so I think I will start with the obvious first. I am sure you already tried some of this, but it is worth asking anyways... Are you using static or dynamic addressing? Can you ping the other computers on your network? Can you ping 127.0.0.1? Do you have any entries in the event log that points to your problem? If the last thing that you did was load IIS, why don't you remove it to see if that helps.

Thanks Joshuacat. By the way the Mrs. says you have a beautiful baby.
My router uses 192.168.1.1 . I use static.
The main card is 192.168.1.111
I have a four port ethernet card, DEC PCI DEChip 21140.
IPs are:
192.168.1.112
192.168.1.113
192.168.1.114
192.168.1.115

It takes a while to boot so I'll get back to you on the IIS solution, also the LOG.

Thanks acklan.

I used to look after a few networks with NT 4, but that was quite a few years back.
I always found NT to be a pain to configure devices. It's a lot lot easier today with XP. I even looked after a couple of HP Netservers, but we had Netware on them. Install Netware ..walk away.. and you never see the server again except for back-ups. - I may be stretching the truth a bit here.

....anyways going a little off topic...Let us know what you end up doing.

OK I have one error message in the event log.

When did you start getting that message? Are using the DHCP Relay Agent?

You could also use IIS 4.0 with NT 4.0.

IIS 4.0 Recommended Installation Procedure

I did not modify the NT box. I changed all the other computers to Static IP. When I changed the router over is when I noticed the problem.
FYI: I changed to static because I was tired of chasing LAN IPs when the power went out. I use VNC to monitor the other computers (Kids).

As I write this I think I will change the router back and see what happens. As long as the computer are static it does not matter what the router is set at, right?

Okay Acklan. Let us know how you make out with this.

I am not exactly sure what you are asking.

here =>

I have my computers with static IPs. Do I need to set the router as static also? I now it does not effect the PCs, but will setting the router to Static IP for the LAN affect the server (windows NT4)? Should I leave the router DHCP for the LAN?
My internet I is dynamic.
I will up grade to IIS 4.0 as soon as I get back on line. Thanks for the link.


Merry Christmas John

The router would be static, and the computers can be dynamic or static.
Just don't configure the computers with an IP that would be assigned by DHCP.
Can you not use computer names with VNC? It's been a few years since I have used VNC.
I always use computer names with PCanywhere and ZenRC at work. But, the computer names are registered.

You could also be able to configure DHCP on the server...since you already have a router...why would you... Just make sure you're not using the router and the server to assign dynamic IPs....

Have a great holiday!

Gotcha. Everything but the server is static.

No. VNC only allows IPs. The paid verison may allow names.

I can't figure out how to disable DHCP on Win NT4.

Router 192.168.1.1
Server 192.168.1.111

First of all... always start off on the physical layer... is there a link light? Is the RJ-45 tip loose? ect...

Then start off in software... you say that you got an error code stating "The DHCP Relay Agent service failed to start due to the following error: The system cannot find the file specified."? Correct?

Is there a specific reason that you are using that service? More than likely the reason for that error code is that somehow the .ini (or whatever extension the service driver/process is using) file is corrupted or was moved/deleted- this could happen from it not completely unloading itself before windows shuts down... or various other things...ANYWAYS... before I get too far off on a tangent.

The way to change/disable DHCP on NT server would be -right click on your network neighborhood icon...chose properties- then ip address, should have the option to enable/disable DHCP. You might also solve the problem by uninstalling/reinstalling the DHCP Relay Agent Service.

Oh, before I forget go to C:\Winnt\Profiles\All Users\Start Menu\Programs\ Administrative Tools

in that folder you will find some admin tools for NT... but the one I am sure you will be interested in is called

dhcpadmin.exe

The link light is present and is actively working. The NIC (All 5 NIC) report working properly.




Correct.



Nope. I just can't turn it off. I changed it from automatic start to maunal start but the change won't stick.



The NIC is setup for static not DHCP. It is setup like the other computer with a unquie IP. I have 13 computers on my LAN.
I did not think about uninstalling the DHCP Relay Agent Service. I am at work till tuesday 07:00 hours, and will not be able to try this until later that morning.
Your advise is invaluble. I will let you know the outcome.

Merry Christmas.

You are right.

Sad to say it was not there. I was setup static IP so the DHCP was off for the adapter already. I tested the connection at the NIC and it shows OK. I cannot ping the LAN or WAN.

Well it's been a grand run. If no one has any more advice I think I'll pull the pin and drop the format grenade and wipe it all out.


Fire in the hole!!!

I have a few more last minute suggestions.... Have you tried to remove and re-add TCPIP? You may also have to reload SP6a after that. Is your network card set for the right speed and duplexing. If the server is that old, it would probably be 10Mb and half duplex.

What do you get when you type IPCONFIG?
What happens when you ping 127.0.0.1
Could you try another NIC card?

I have a good 3Com 3C905cTX (100T/full) installed. I did swap trying everything.

IPcomfig= It flashes black them back to the desktop.

127.0.0.1= good return. <10ms

Try it from the command prompt.
Start, run, CMD or Command. IPCONFIG

I believe it was command.exe with NT

If that doesn't work...

You could also try to set the card to 10Mb half duplex.

Try IPCONFIG again.

OK all 5 ethernet port aquired the subnet mask, gateway, and reported thier LAN IP

Via IPconfig

Is that really any different...

Are you getting your DNS settings from your service provider?

From the command prompt.(on the server)
Can you ping the other computers on your network?
Can you ping www.google.com ??
Can you tracert www.google.com

From the command prompt.(on the one of your other computers)
Can you ping the server?

Yes I have input the DNS IPs manually (static)..

68.109.202.25
68.109.202.30
68.11.16.25

The rest of my computers (11 total) are setup the same way, static.

oooooooo you are good. My XP machine pinged are received a return with none lost.

So the DNS setting fixed it? And, also switching to 10/half?

Did not set to 10 haft but the DNS is manully configured. I don't understand this. It was working until 3-4weeks ago. I'll set to haft 10T.

Sorry been offline for a while...



had a couple of problems with my gateway and my pc crashing at the same time... plus work...lots of it.
Before we start... flush all DNS/ DHCP- go to command prompt and type "ipconfig /flushdns" then
"ipconfig /registerdns"


Go to command prompt... see if you can see other computers on network...
...type net view... you should see a list of computer names of other computers on network...
...if not lets just take a look at your DNS cache and Host/LMHosts files to make sure they're working properly...

before you go on... try to ping other computers using ip and hostname (both local and internet)... if this works it should set some names in your Hosts/LMHost files as well as your DNS cache- before I forget- if any of this fails it could be because you have a program (i.e. anti-spyware/virus locking down your LMHost/Host files... in rare cases this has been known to cause connectivity problems on a LAN/WAN stemming from the inability of that computer to look up other computers NetBIOS names)

to view cache- once again from the command prompt type "ipconfig /displaydns | more" (| more just breaks it down into manageable chunks)

to view LMHosts file it should be at %SystemRoot%\System32\Drivers\Etc
same with the Hosts file...

If the above are all good, then more then likely it is not DNS/WINS and we can move onto other troubleshooting....

It is set like you described.

Everything that I have described is good?

You can view other computers on the network,
You can ping other computers on both your internal network and the internet- by both ip and hostnames?

You can view your DNS and LMHost/Host files and they all have entries in them other than 127.0.0.1 ?

What settings is your NIC running on, and did you try re-installing the drivers for it?

Also what kind of router... what are the settings for it ?

Does it pull the DNS from your ISP?

Is your server pulling DNS from the router or from your ISP?

Why are you using port forwarding from 8080?
(for the hosting of your kids web pages?)

Do you have another NT box that works?
(you might try using the same exact settings as it, then make one modification at a time till you get it where you want it)
