Andrew, We also saw another case of usage of this fixed session key other than loopback behavior in NTLM. Based on your testing before, could you tell me the repro steps, or scenario , so I can have a repro to debug it ?
Thanks!

Please let me > know if you have more questions. This is not the case, or else we would not know about it, and would not need to deal with it for interoperability. Sadly you will need to dig deeper, as we discovered it the hard way (ie, needing to discover the magic fixed key by DES brute force), I can assure you it is used outside the server.
