OS_DOMAINMEMBER

When the IsOS function is given OS_DOMAINMEMBER as its dwOS argument, it answers according to whether the NETAPI32 function NetGetJoinInformation reports that the local computer is joined to a domain.

The answer is sought only when the function is first called (per-process) for this case of dwOS. The function returns TRUE if

• the platform is NT and the major version >= 5 (as for OS_WIN2000ORGREATER)
• and the NetGetJoinInformation function is found
• and a call to this function for the local computer produces NetSetupDomainName as the join status

Availability

The OS_DOMAINMEMBER case of the SHLWAPI function IsOS is supported in version 6.00 and higher.
