Bind 8.2.2.p5 NT problems

[Mikael Forsberg]

Hi,

I found the cause of the below problem.
It was a bug in the NT port. (socket.c)

Also my previous problems with the ixfr file and log file that
growed forever were caused by the NT not allowing rename(From,To)
when the file To already existed. (logging.c and ns_ixfr.c)

Had also problem with RAS, Remote Access, together with NT,
as many others.(named.exe crashes immediatelly at startup)

The solution, seems to work (at least were I have tested it)
It assumes that the RAS service is installed as "RemoteAccess",
but I'm not sure how it is in non English versions of NT,
and that the RAS interface is listed as the last interface.

Have anyone a better solution?

Are the corrections for 8.2.3 and the latest Nortel fix available as
source files?
Are they possible to include and recompile in 8.2.2p5?

Regards

Mikael
