SYMPTOMS
In Windows NT 3.51 the version of LogonUser API prevented a user from accessing the network while the interactive or batch logon right was given to that user.



CAUSE
This was due to the fact that the Logon From Network right was removed for that user. For Windows NT 3.51, the Network logon-type support was removed, because at the time it was deemed too confusing for the user.



WORKAROUND
To resolve this problem on Windows NT 3.51 Workstation or Server, obtain the fix referenced below, or upgrade to Windows NT Workstation or Server version 4.0.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
The API confusion was based on the fact that Interactive and Batch logons allowed the logon session to go out on the net, while the Network logon would not allow the logon session to go out on the net. However, with the exposure of DuplicateTokenEx, this potential confusion has been documented in the Win32 SDK, and should no longer pose an issue. The Logonuser API is called from advapi32.dll.
