I'm struggling with this vulnerability : SSL Certificate - Subject Common Name Does Not Match Server FQDN. It says in the description that this may be due to not having reverse DNS lookup, but we have it and I can ascertain nslookup for the IP does resolve to the FQDN.
We're scanning a windows 2008 R2 machine and we have installed a certificate issued by our DC, which we've also added as a trusted CA in Qualys Guard. The only thing I can see is that there may be a case mismatch, that is we're using BIND for (reverse) DNS that is returning a string like :
