I have a nice target to play with: a well known German car manufaturers FULL workshop parts CD (15 CD's actually).

This expects a LAN ID and a serial key that
matches the LAN ID. I patched the program
in a suitable place to get around this. OK for
now. But the parts CD's are updated every 3 months and I actually know one real serial to a particular LAN ID.

So my question is HOW TO FIND and CHANGE the LAN ID of MSLoopback adapter ? If I can change it to a required ID then voila. This would FIX the problem for a while

I am starting this project now but if anyone has some info TIA.

Let me know which OS you are using and I can see what you need to do. The M$ Loopback adapter is used differently on each OS.

Write a tutorial -please!

P.S. I'm using mostly Win2k and if possible help on Win98 would be appreciated but not necessary.

Hi, I had forgotten all about this problem
as I made the guy purchase a NIC with software changeable ID :-)

I had read that Linux could assign any number to a card but found no MS stuff on this topic.

I am still curious to know what is going on with this MS Loopback adapter for the record.

I use WinNT4 SP6

TIA

Software changeable ID?-- Where did you buy.

Hi

I discovered a 3Com Etherlink XL 10/100 PCI that you have the option to change the address under properties/advanced...but maybe this is the O/S Win2K that allows a change ???

Anyway I would still like to see how the MS loopback adapter is assigned an ID... ??? cos the guy really has no need for an 'actual' adapter as it's a standalone machine

This won't necessarily work for all ethernet cards, but:

In Windows 95/98 and NT go to windows registry (use command regedit) and add a new stringvalue line "NetworkAddress=000011112222" to your Ethernet adapter parameters section (substitute 000011112222 by desired MAC address). In Windows95/98 the path to Ethernet adapter is something like:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0000].
In Windows NT the path is something like:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NE20001\Parameters].
The actual path will depend on the number and type of installed adapters. Reload the computer for the change to take effect. Use commands winipcfg (in Windows95/98) and ipconfig /all (in Windows NT) to check the current MAC address.
In UNIX use following commands to change MAC address of the Ethernet interface:
host# ifconfig eth0 down
host# ifconfig eth0 hw ether 00:00:11:11:22:22
Use command ifconfig eth0 to check the current MAC address.
