DOCUMENT:Q159702 21-FEB-2002 [winnt] TITLE :Exception Error in Nwconv.exe During Migration PRODUCT :Microsoft Windows NT PROD/VER::3.5,3.51,4.0 OPER/SYS: KEYWORDS:kb3rdparty kbnetwork kbtoolkbfaq ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you attempt to migrate user accounts and data from Novell NetWare 3.1x servers to Windows NT 3.5, 3.51, or 4.0 servers using the Migration Tool for Netware (Nwconv.exe), the Migration Tool for NetWare may stop responding with an exception error 0xc0000005 in Nwconv.exe and generate a Drwtsn32.log file. CAUSE ===== During migration, the Migration Tool for NetWare builds a Printer Operators member list. It enumerates all the print servers on the NetWare server and then builds the user list of who is in the Printer Operator group associated with the respective print server. The Migration Tool for NetWare sets a buffer size to hold a print server name less than or equal to 20 characters, including the null character. NetWare allows less than or equal to 47 characters for the print server name. Unexpected results may occur when you read a string into the buffer of a smaller size. In this case, the result is an exception error in Nwconv.exe. RESOLUTION ========== Rename all the print servers to be less than or equal to 19 characters. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT versions 3.5, 3.51, and 4.0.
