If a Windows 2000-based domain with NTLM version 2 levels above 2 is trusted by a Windows NT 4.0-based domain, authentication problems may occur. When you log on to a Windows 2000-based computer (as a member of the Windows NT 4.0-based domain), you can access shares on the primary domain controller, but not on any other member server in the trusted Windows NT 4.0-based domain.
Also, a Windows 2000-based cluster that is running the higher level of NTLM 2 does not authenticate a joining node if both nodes are part of a Windows NT 4.0 Service Pack 6a-based domain. The node that attempts to join the cluster does not succeed and the following error is recorded in the cluster log:
[JOIN] Unable to get join version data from sponsor "ip address" using NTLM package, status 5.
The token that is returned by the Windows NT 4.0-based computer has a TokenSize value that is less than the Windows 2000 token if the NTLM 2 level is set above 2. This causes the TargetName and TargetInfo values to be null. Windows NT 4.0 has a function for a logon target that does not allow a null server name with high security, which causes the authentication problems.
