SYMPTOMS

All messages received on the SSCP-LU session via SLI_OPEN or SLI_RECEIVE API calls are truncated to 256 bytes of data. The SLI_OPEN returns with AP_OK while SLI_RECEIVE returns the following error message:
LUA_DATA_TRUNCATED.
This problem occurs with the SNA Server Windows 3.x and Win32 SLI API interfaces.

CAUSE

This is a problem in the SLI library. It is limiting the size of SLI_RECEIVEs on the normal SSCP flow to 256 bytes, whereas many hosts send larger RUs than this on the SSCP-LU session.

RESOLUTION

Microsoft has updated the files, WINSLI.DLL and WINSLI32.DLL, to correct this problem.

STATUS

Microsoft has confirmed this to be a problem in SNA Server for Windows NT. This problem was corrected in the latest SNA Server for Windows NT, 2.11 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
