You seem to be using a native copy of dnsapi.dll,
and seems unhappy that Wine's ntdll.dll lacks an implementation
for RtlIpv6AddressToString().
I suppose there's some chance that function would be very
easy to implement.  I'm cc'ing wine-devel in case somebody has an opinion.

You could also grab the dnsapi.dll from ReactOS and see if it helps
your app. Unfortuanly we can't release it to Wine even it works
because it was based on a GPL library.

Thanks

Thank you for that suggestion.

I've just tried building dnsapi.dll from ReactOS form their sources (0.2.8  
RC1, from http://sourceforge.net/project/showfiles.php?group_id=6553).

I was able to successfully build that dll (using mingw cross compiler).  
However, dnsapi.dll they provide doesn't have some of methods that native  
win has, and appreantly nslookup.exe and similar apps require.

BTW, from their web pages, not all is GPL, they also have some LGPL, maybe  
it would be worth investigating.

This is except from output form wine, using ReactOS dnsapi.dll:

warn:module:import_dll No implementation for  
DNSAPI.dll.DnsFreeConfigStructure imported from  
L"Z:\\home\\rbr\\src\\bwapps\\nslookup.exe", setting to 0x7f880000

DNSAPI.dll.DnsQueryConfigAllocEx imported from

warn:module:import_dll No implementation for  
ntdll.dll.RtlIpv6AddressToStringA imported from  
L"Z:\\home\\rbr\\src\\bwapps\\nslookup.exe", setting to 0x7f880022

--- and then it failed:

I've checked their dnsapi DEF file, DnsQueryConfigAlloc is not there, so  
it wouldn't be just simple hack to make this run :-)

Oh, well... Thanks anyway.
