Bind9 can't resolve mbs.microsoft.com

  • 772

Our Bind 9 on Ubuntu 10.04.4 (9.7.0.dfsg.P1-1ubuntu0.8) can't resolve mbs.microsoft.com. Other Nameservers seem to be able to resolve the Name.

This is what bind logged on debug 9:

query failed (SERVFAIL) for mbs.microsoft.com/IN/A at query.c:4628
bind

  1. There may be many reasons for SERVFAIL; According to the source code this problem appears because "Something has gone wrong". My suggestions is to start with:

    dig +trace mbs.microsoft.com

    on a problematic Ubuntu, then compare results with other servers. I would also inspect the named.conf file to ensure that there is no problems with i.e. forwarding, etc. Good luck.
