SYMPTOMS
LAN Manager servers running any version up to and including 2.2c may experience a Trap D error with the SOCKDRV.OS2 driver, which is as follows: Trap 13 (0DH) - General Protection Fault 0000 AX=47FC BX=47F8  CX=FF00  DX=4FB8  SP=0F32  BP=0F42  SI=07FC  DI=FA28 IP=5354 CS=0878  DS=0870  ES=0870  SS=1980  -- NV UP EI PL NZ NA PO NC GDTR=1F5B00 2B5F  IDTR=11344C 03FF  TR=0010  LDTR=0028 IOPL=2 MSW=PM MP TS 0878:5354 268B4702      MOV     AX,WORD PTR ES:[BX+02]     ES:47FA=INVALID



CAUSE
Trap D errors occur when a socket driver tries to access the ES segment using offset, which is far beyond the ESLIM.



STATUS
Microsoft has confirmed this to be a problem in Microsoft LAN Manager version 2.2c. A fix to this problem is in development, but has not been regression-tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information on the availability of this fix.
