can assist you in designing a more robust name architecture for
ease of maintenance, and in building a DNS structure to work
more effectively with Active Directory.
services for DNS, although closely related technically, fall
into three groups from a management perspective:
Auditing informs you of the actual state of affairs from an unbiased
point of view, according to established standards. This can also
serve as a "sanity-check" of requested or planned projects.
This can be performed for inside (behind the firewall) and outside
(visible to the Internet) name servers, as desired. These are
performed under contract for a proposed, fixed price.
Troubleshooting - Given
a problem, we will work with your staff (remotely, or on site)
and will go through the steps necessary to identify the root
cause and correct the situation. If desired, we can do this in
conjunction with your staff to train them in troubleshooting
techniques. These services are billed on an hourly basis.
- Often, your staff already understands the fundamentals of running
a name server, and simply needs assistance with policies, practices,
and architecture in order to perform the job themselves. We will
provide this on-site or remotely as best fits your needs. These
services can be performed as formal, fixed price training sessions
(plus travel expenses if necessary), or billed hourly, depending
on the need.
Evaluation may also make or prescribe the necessary changes,
at your option, and prescribe the purchase of additional hardware
or software as required. If requested, Network Evaluation will
install and configure those items for seamless operation within
All external auditing activities will require verifiable, written
permission and/or proof of ownership for the target organization,
and a formal signed contract. This is required to protect both
the audit's target and Network Evaluation.
