By default, the server broadcasts its availability on the network every 2 seconds. While broadcasts cannot be disabled completely, you can specify a custom broadcast interval in the registry under the key [HKEY_LOCAL_MACHINE\SOFTWARE\Access Remote PC\<VERSION>\Server\Settings] as a DWORD value named "nBroadcastTimeout". The value is in milliseconds. You can set the broadcast timeout to anywhere between 20 milliseconds to once per 1000 seconds (about once per 17 minutes).

[HKEY_LOCAL_MACHINE\SOFTWARE\Access Remote PC\<VERSION>\Server\Settings]
"nBroadcastTimeout"=dword:00002000

The maximum allowed value is 1000000. By default, the nBroadcastTimeout value is not set in the registry. If the value is missing, the default value 2000 is used.
