    Rhoderick Milne [MSFT]

    Rhoderick Milne [MSFT]
    When we are performing the Exchange Risk Assessment, one of things PFE love to check is how servers have been configured for IPv6.

  • Blog Post: How To Check Exchange Autodiscover SRV Record Using Nslookup

    Rhoderick Milne [MSFT]
    Generally the Exchange external Autodiscover DNS entity is configured as a regular A record. Sometimes a service record (SRV) is used instead. Since I have the habit of forgetting the syntax of quickly querying for the SRV record, this is one of those shared bookmark posts! Nslookup is the tool of...

  • Blog Post: VMware Issues With Exchange DAG

    Rhoderick Milne [MSFT]
