@pablo That setting doesn’t seem to permit the user to change the MAC in the GUI to even a 00:0c:29 kind of old-school VMware mac. It used to, but not any more.

Hi Daniel,
Just do it right now. Flexlm is starting normally after forcing the MAC on the E1000.
Version of flexlm is 9.5.0 if it could make difference.
Also, depending on vendors, the license file could have the MAC and/or the volume ID of the C: drive to check against. You could change it by using Volume ID from Mark Russinovitch (now Microsoft) at http://technet.microsoft.com/en-us/sysinternals/bb897436

I also was able to use the E1000 to set the locally administered address, but after a reboot FlexLM complained about the MAC address not matching. After checking the lmrgdlogs, indeed FlexLM only saw the VM’s auto-populated MAC address and NOT the custom locally administered one I entered. Anyone else run into this problem?

Jim’s post worked for me.

you can also put

ethernetX.checkMACAddress = “false”

in the vm’s configuration file, to prevent checking of MACs.

Jim, you’re brilliant. I couldn’t get the VMXnet3 adapter to accept the spoofed MAC, but the E1000 did the trick. Thanks for the idea!

I was able to get this work but I had to change the nic in the vm from the vmxnet 3 adapter to the e1000 adapter. The e1000 adapter actually has a setting in the driver advanced tab that lets you set a mac address. The setting is called Locally Administered Address

Hi Chad,

I left it at auto at the VM level. The only difference between the two scenarios seems to be that I did not import the physical machine, but instead set up a fresh 2003 server from a template. I would try that to make sure it isn’t a 2000 server issue.

Cheers

Hey, I have the exact same issue. I have an old legacy Win2k server with FLEXlm on it. I did a P2V into ESXi 3.5. After I set the MAC address as you did I lost my network connectivity. A reboot didn’t help. I was wondering if you also reconfigured anything at the VM level for the MAC or did you leave those settings at the defaults (auto MAC). Other thoughts?

Thanks.
