Anyone tried getting an ATM NIC on Windows 2000 to work with an Lightstream 100 and Catalyst 5000 LANE blade? I suspect Microsoft's lack of backward compatibility in their Windows 2000 ATM implementation is preventing this setup from working. I'm using a Marconi Forerunner LE 155 adapter. >From what I can find, the LS100 only supports UNI 3.0 and the help files in W2K says Microsoft's implementation is UNI 3.1. I tried using both auto-configured LECS address from the LS100 and using the well known LECS address (5155 on Cat 5000 being the LECS, LES/BUS, 12.0(9) something code). If anyone out there has any experience with ATM NICs and Windows 2000 talking to Cisco equipment, let us know your experiences. Meantime - gotta yank the card out and get it into my other test machine with NT4 (I know the Marconi drivers for NT4 has a UNI 3.0/3.1 selection option). Couldn't get my 3Com 3C339 Token Ring PCI card to work with W2K either - no drivers. P/S - It sure feels like Token Ring is dying - with the slowly dwindling supply of decently supported NICs for it.
