Windows proxy deployment

For detailed discovery of the Windows part of the target environment, BMC Discovery uses a Windows proxy, a discovery proxy that can be installed on any suitable Windows computer in the target environment. There are two Windows proxy types available, which you can select depending on whether credential, workgroup, or active directory security is used. The preferred approach is to use the active directory proxy installed as a service that is set to run as the discovery user. In this manner, a Windows administrator can set the user name and password, and it never has to be known or entered by a BMC Discovery administrator. In the case of the credential Windows proxy, user names and passwords for discovery are entered directly into the appliance UI.

The Windows proxy can be a physical or virtual server, and it can use an existing infrastructure server.

The following table provides information about the compatibility between Windows proxy types and versions, and the operating systems that the Windows proxy runs on for BMC Discovery.

Workgroup Windows proxy

The Workgroup Windows proxy is no longer supported. Running the Active Directory Windows proxy under a Workgroup account provides exactly the same functionality as the old Workgroup Windows proxy.

Minimum host specification

The following are the minimum recommended specifications for the Windows proxy host:

Component

Specification

Operating System

As stated in tables above

CPU

2GHz Intel Pentium® 4 CPU 512k Cache (or equivalent from other manufacturer)

Memory

2GB

Hard disk

60GB

To avoid any impact during resource-intensive periods of discovery, we recommend not to install the Windows proxy on any host supporting other business services. This is true even if the minimum Windows proxy specification is exceeded, since the Windows proxy will attempt to use what resources are available, in order to optimize scan throughput.

Windows discovery communications

You should also consider the ports that will need to be opened in any firewall between the appliance and the proxy or proxies, and the proxies and target hosts.

Windows discovery metadata

Discovery metadata covers Windows as well as UNIX. This provides information about why sessions failed to be established and why scripts failed to run, including information about what credential or Windows proxy was used.
