Under Windows 98, I can go into the Network properties and add more than one TCP/IP protocol. For example, having one that works on DHCP and another that works on a fixed IP address.

This is what I'd like to do with my Windows 2000 box: Have it do both DHCP as well as assign a fixed IP.

The purpose is so that I can talk to the Empeg over ethernet without having to switch the Empeg's mode from DHCP (to match my office network) to fixed (to match my home network).

The only problem is that I can't seem to add another TCP/IP protocol to the network panel in Windows 2000. At least not the way I can in 95/98.

I can add more than one fixed IP address to the TCP/IP protocol in Windows 2000, but I can't figure out how to mix a fixed address and a DHCP address in Windows 2000.

Anyone else know how to do this?

I don't run 2000 at home, so I can't check this, but I set up a presentation laptop a while ago...
There is a dummy interface "adaptor" available in the network properties, just add one for each IP.
Sorry I can't be more specific... =)

Darn, I wish there was a way you could look this up. I can't find a way to add a dummy adapter. I understand why that would work, and I think I know how I'd go about it if I could only figure out how to add a dummy adapter.

I'm sure it was as simple as network properties, add, adaptor, microsoft virtual adaptor (or something like that)... I remember being surprised by how easy it was, as I was expecting the usual M$ trouble... =)
We used it on a laptop running Domino server to set up 6 virtual domains for a website presentation. We did this so it would look like it was actually on the internet, whereas in reality no phone connection was available... =)

I'll try to "borrow" a win 2K machine at work tomorrow and check it out...

Exactly. That's the first thing I tried. I don't get "Adaptor" as one of the options I can add. All I get is Client, Service, and Protocol. And when I try to add a protocol, TCP/IP isn't offered (I assume because it's already installed).

Hmm... I tried pulling up additional protocols, it gave me the option for TCP/IP, it let me install it, but it doesn't show up as a second configurable protocol. I also tried the Add New Hardware wizard, but the only MS adapter available was for loopback. Still thinking about it...

While you were posting this, I found the MS KB article about the loopback adapter. I am trying it now. Let you know in a sec...

Tony Fabris

When you add the device "Microsoft Loopback Adapter" via that add/remove hardware wizard, you get another Local Area Connection named "Local Area Connection 2" that's attached to this adapter.

I tried setting it to a fixed address on the same subnet as the Empeg, but I still can't ping the Empeg's fixed IP address from my computer. Maybe the loopback adapter isn't meant for this kind of behavior.

What about a hardware profile???

What about a hardware profile?

I'm interested in having this work 100% of the time, not having to switch hardware profiles. If I'm gonna do that, I might as well do what I'm already doing, which is switching the Empeg back and forth between fixed and DHCP via the USB cable.

There is no way in 2000 to have a static IP and a DHCP IP on one adaptor. NT 4 had the same limitation, but Windows XP does correct this oversight. It's possible a future service pack may also add this ability to 2000.

A possible dirty solution - do you want to run a small (1 IP) DCHP server on your home net? Are you running W2K Server or Professional?

Or just use USB at home and DHCP in the office... =)

Do I get this right Tony? Why would you want to use DHCP on your win2000 box? Have you got a DHCP-server running at home which should assign a second IP-address to your win2k box?
I guess the way you want to go is assigning two IP-adresses to the empeg's NIC. One (eth0) gets assigned an IP-address by the player-app using DHCP and the other(eth0:0) should be fixed. It involves a new kernel including IP-aliasing. I can remember I had it running this way with some modified init-script.
I do not use it anymore though; I'm also administering DHCP/BOOTP at work, so I gave the empeg an unlimited DHCP-lease and switched DHCP off on the empeg. Problem solved...

A possible dirty solution - do you want to run a small (1 IP) DCHP server on your home net?

Yes, one day I will be running DHCP at home. As soon as I get a broadband connection to my house, then I'll have one of those NAT router/firewall boxes doing DHCP. But not right now. For now, I'm just going to run fixed IP's at home.

Are you running W2K Server or Professional?

At home, neither. All the boxes on my home network are Win98. Plus, none of them are "always-on", so I can't effectively run a DHCP server on my home LAN at the current time.

Or just use USB at home and DHCP in the office... =)

Yes, I can run either USB or ethernet at home and at the office. But the whole reason I want to get ethernet transparently working in both locations is because I like Displayserver.

Specifically, I use Displayserver as a tool which lets the Empeg become a home->work file taxi with hundreds of megabytes of capacity. Who needs zip drives when I'm already carrying the empeg back and forth between home and work?

It works like this:

- Anything I want to taxi, I zip up into a file called TAXI.ZIP.
- Rename TAXI.ZIP to TAXI.MP3
- Use Emplode to put TAXI.MP3 into the "Unattached Items" playlist.
- Take the empeg to the other location (home or office).
- Use Displayserver to grab TAXI.MP3 out of that playlist.
- Rename it and unzip it.
- Use Emplode to delete TAXI.MP3 from the empeg.

Now, you only need ethernet at the destination end of that transaction. My problem is that I do this sort of thing in both directions, on networks that are configured two different ways (home=fixed IPs, work=DHCP on a different set of subnet addresses). So whenever I switch directions, it requires me to do the extra step of re-configuring the Empeg to recognize the other type of network.

I was just hoping I could add a fixed IP to Win2k that allowed it to work on the same subnet as the Empeg.

Why would you want to use DHCP on your win2000 box? Have you got a DHCP-server running at home which should assign a second IP-address to your win2k box?

Just the opposite. The Win2k box is on the DHCP network at work. The fixed IP addresses are at home and I have no DHCP server at home.

So every time I'm at home, I need to configure the Empeg to be 10.0.0.43, and every time I'm at work, I need to configure the Empeg to be DHCP and to pull an address from my work LAN's pool.

If I don't do this, since the Work LAN's IP address pool is on a different subnet than 10.0.0, my Win2k PC refuses to talk to the Empeg even if I feed it the IP address directly.

I'm guessing adding a second NIC to the 2000 box is out of the question?

Sounds like you need a USB taxi program... =)
Thanks to the work done by Frank, I've got the connection working both ways under windows...
At the moment you need the developer image on the empeg, but I'm sure something better will appear in time... =)

Heh. Don't think that didn't cross my mind!

Still, it would be immensly frustrating to have to go to that kind of trouble, when (as Drakino pointed out) I'd essentially be working around a software limitation by adding hardware.

I mean... half a dozen clicks in Win98 will get me a second TCP protocol attached to the same card. Why not the same thing in Win2k?

Plus, I don't have any extra NICs laying around right now. Was looking for a quick software solution.

Couldn't you have a chat with the network admin to set you up with a permanent lease for your empeg? Have it get the lease once and then shut off DHCP on the empeg.That way you could add a second ip on your home win98 box in the same subnet as your work IP.

BTW some network-admins can get mad when you try to use private ip-adresses (10.10.10.10) on their network

Well, I've got a quick and dirty version working, but you need to use the serial shell to start the transfer...
If you are running the developer software on the empeg, you are welcome to try it... =)

I don't have the ability to request a permanent lease from my DHCP server, but I do have a handful of fixed addresses on my LAN that I am free to use however I see fit. The addresses are reserved for things like servers and routers. I have considered doing exactly what you said: Assigning a fixed IP to the Empeg that falls within that range.

(I know this sounds a little strange. I'm the network admin for my local department, so I control the local servers. However, I do not control the DHCP server. Corporate HQ controls the DHCP server and has given me the specs for it, including what the fixed addresses are reserved for.)

The problem is that the range of available fixed addresses on my LAN is very narrow. I need them for future expansion.

Just out of curiosity, would it work on a Mark1 as well?

Silly question:

I assume you're running some sort of dual homed machine to share your highspeed connection? This is probably doing NAT of some sort? Why not give your home network an illegal copy of your work's IP space and then have the empeg use a fixed (work) address? If you connect to an office resource from home, this might be a problem if your home network shares an IP with the (legitimate) IP address you're trying to access at work. Apart from that, the outside world never sees you IP addresses (assuming you NAT solution is working 100%), so it shouldn't really care.

-Zeke

just say you weren't paying much attention...

I could do something like what you suggest (change my home network's fixed addresses to be the same subnet as my work), but it would involve assigning a fixed IP address to the empeg that takes up one of my scarce fixed addresses on the work network.

What I want is to do it the other way around: Use a fixed IP address on the Empeg that's the same as my home network (and different from my work's subnet), but the fact that Win2K won't let me be on two subnets at once is the thing that's stopping me.

Wow, it's amazing how much trouble a simple Win2K software limitation can cause, eh?
