SYMPTOMS

After you open a socket of type SOCK_STREAM by using the ATPROTO_ADSP protocol, and bind to a dynamic socket, the setsockopt() function fails under these conditions:

The setsockopt() function uses the zone name returned by getsockopt() (also found by looking at the control panel network entry) with the SO_LOOKUP_MYZONE option.
The zone name is supplied to setsockopt() with the SO_REGISTER_NAME option.

Error code 10022 (WSAINVAL :Invalid Argument) is returned on calling GetLastError().

RESOLUTION

Instead of passing the string returned by getsockopt() for the zone name, use the character "*" for the ZoneName member of the WSH_REGISTER_NAME struct. For example, use this:

   WSH_REGISTER_NAME regName;
   ........
   strcpy( regName.ZoneName, "*");

instead of this:

   strcpy( regName.ZoneName, "BLDG/1");

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was corrected in Windows NT 3.51.
