Incomplete Server List in File Manager Connection Dialog Box

• Microsoft Windows NT Server version 3.51

SYMPTOMS

Windows NT Workstations and Servers do not see all the Servers available in a domain from the Connect Network Dive dialog box in File Manager. Attempts to browse the domain from a command prompt with the NET VIEW command succeed with all the servers shown correctly.

CAUSE

The Shared Directories list box generated in the Connect Network Drive dialog box fails to enumerate a complete list of servers. The enumeration of servers is incomplete because the buffer passed from MPRUI.DLL (responsible for filling the list box) to NTLANMAN.DLL (responsible for enumerating the servers) to retrieve the list of server names is too small. NTLANMAN.DLL returns a status code indicating that a larger buffer size is required to hold the server names, but also returns some unexpected server names in the small buffer. MPRUI.DLL resizes the buffer, but does not add any of the unexpected server names returned from NTLANMAN.DLL in the original, smaller buffer to the Shared Directories list box.

The incomplete list of servers is caused by NTLANMAN.DLL returning server name entries while requesting a larger buffer size from MPRUI.DLL. The set of circumstances that cause NTLANMAN.DLL to return server names, and request a larger buffer size are very infrequent resulting in about six server names being dropped from a potential list of three hundred.

RESOLUTION

This problem has been corrected in the latest Service Pack for Windows NT version 3.51.
