Memory Violation Running Attachmate Extra! for Windows in WOW

 Last reviewed: March 15, 1996
Article ID: Q141753
The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.5 and 3.51
  • Microsoft Windows NT Server versions 3.5 and 3.51

SYMPTOMS

Attachmate's Extra! for Windows uses an MS-DOS TSR to interface with DLC. This works fine on Windows for Workgroups, but not in Windows NT DOS/WOW. When DLC.CLOSE.STATION is called, a 32-bit pointer is returned instead of a 16-bit pointer. This pointer may point to code in KRNL386.EXE and causes a memory access violation.

RESOLUTION

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

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):
