WINSMODE

Descriptions:
The WINS-MODE feature and the MULTI-HOMED feature are separate in Shadow IPServer. The WINS-MODE feature must be enabled with a checkbox (on the IPManager) or the WINS-MODE keyword in the NTS-SRVR.CFG file. This description does not discuss the implications of the WINS-MODE behavior, but you may recognize some of your old friends like the master browser [1D] , and the domain controller [1B] and the browser election group [1E] .

1. Checking:
   
   • The following name registrations must be GROUP :
     <name> [1E] names with the 16th byte EQUAL to 1Eh (0x1E)
     <name> [1C] names with the 16th byte EQUAL to 1Ch (0x1C) [0102]__MSBROWSE__[0201]
   • The following name registrations must be UNIQUE :
     <name> [1B] names with the 16th byte EQUAL to 1Bh (0x1B) <name> [1D] names with the 16th byte EQUAL to 1Dh (0x1D). Otherwise a "refused" (5) code is returned.
2. Groups:
   
   • <name>
   • [1C] names with the 16th byte EQUAL to 1Ch (0x1C):
     1. The query response is limited to 25 IP addresses. (Which 25?)
     2. If there exists a registration for
        <name> [1B] names with the 16th byte EQUAL to 1Bh (0x1B) then this entry is the first in the query response list (with the group flag on).
   • 
     
   • <name> [not 1C] names with the 16th byte NOT equal to 1Ch (0x1C):
     1. If there is a registration for this group, a query returns positive with one IP address equal to 255.255.255.255, otherwise a 'name error" (3) code is returned.
3. Other:
   <name> [1D] names with the 16th byte EQUAL to 1Dh (0x1D)
   
   1. A registration always returns a positive response (no challenge)
      
   2. A query always returns a 'name error' (3) code.
