    Windows proxy Ports

    Proxy port changes in 8.3 SP2

    In BMC Discovery 8.3 SP2 and later, proxies are not limited to the default ports.You can also install multiple proxies of each type on a single host. Consequently, in BMC Discovery 8.3 SP2 and later you must check the proxy manager to determine which ports the proxies are using. The defaults are the same as previous releases, but installations of additional proxies use incremental ports. You can also use the proxy manager to modify the port that each proxy uses.
