HostMACid Vs Physical Adress

sunil_j

Hi,

I am interested in understanding the differnce between the Physical Address shown when we execute the ipconfig/all command and the HostMACId shown by the mtlicenseinfo CLT?

On my windows 2000 Server, the HostMACId changes everytime I restart my computer and as such the Metatagger throws an Invalid License error .. whereas the PhysicalAdress remains the same. When I gererate the License using the Phyical Address, the license remains invalid since the mtlicenseinfo shows a different HostMACId.

Does your server have multiple NICs? If so - the order in which they are initialized could be playing havoc with the licensing (which I believe pulls information from the NIC in order to derive the MacID).

I think there's a setting you can put somewhere to resolve this, but I dealt with this only once, and it was close to a year ago (and I no longer have access to the machine on which I did it)... sorry.

Hi,

No, the machine on which I am working has only a single NIC card.

The iwov windows hostmacid comes from Microsoft Netbios, grabbing the first non-zero active macid from the list provided by Netbios. mtlicensinfo should show a hostmacid that agrees with ipconifg /all (or at least one of the ones listed). I do not know the way to insure on an MT Host that the "real" active network interface is chosen if there is a choice.

Do you have a loopback adapter configured?
I seem to recall that there were times when that sometimes caused problems with getting a static macid

I think you can tell by doing an: ipconfig /all
but I don't remember for sure.
