For example (untested):


    PSID GetSIDFromUsername(const AnsiString &Username)
    {
        PSID pSid = NULL;
        DWORD dwSidSize = 0;

        TCHAR szDomain[1024] = {0};
        DWORD dwDomainSize = 1024;

        SID_NAME_USE AccountType;

        LookupAccountName(NULL, Username.c_str(), NULL, &dwSidSize,
szDomain, &dwDomainSize, &AccountType);
        if( dwSidSize )
        {
            pSid = (PSID) GlobalAlloc(GPTR, dwSidSize);
            if( pSid )
            {
                if( LookupAccountName(NULL, Username.c_str(), pSid,
&dwSidSize, szDomain, &dwDomainSize, &AccountType) )
                    return pSid;

                GlobalFree(pSid);
            }
        }

        return NULL;
    }


    PSID pSid = GetSIDFromUsername("joesme");
    if( pSid )
    {
        // use pSid as needed
        GlobalFree(pSid);
    }

The only time I have heard of that happening is when you are trying to
resolve a username that belongs to a different domain than the server that
is specified in the lpSystemName parameter.

That would be preferred.
