DOCUMENT:Q163378 25-MAR-2002 [win95x] TITLE :Microsoft Exchange Hangs Sending Message Using SPX PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:: OPER/SYS: KEYWORDS:kberrmsg kbnetwork win95kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== Microsoft Exchange or Windows Messaging may stop responding (hang) when you try to transmit a message using SPX over a dial-up connection. This problem occurs only if the installed version of NWLINK is dated before 6/27/96 and the Wsipx.vxd file is dated before 3/5/97. CAUSE ===== This problem occurs only when Microsoft Exchange or Windows Messaging is started offline and you use the Deliver Now command to deliver messages over a dial-up connection. The problem occurs because WSIPX submits a larger frame than is supported. SPX checks the NDIS packet frame size against the connection's maximum frame size and hangs or returns a "The message cannot be delivered" error message. The NDIS packet frame size is 1497 bytes and the maximum frame size is 1160 bytes. RESOLUTION ========== STATUS ====== This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows.
