The browse function within NetSupport School, allows you to search your network to find Student machines to connect to. A UDP broadcast packet is sent out to all machines to check that the machines are ready for connection.
By default, this takes twelve seconds and is made up of three scans of your network, each lasting four seconds.
You may wish to change this setting to a longer period if you have a particularly slow network, or to a shorter period if you have a fast network. You can edit the length of time it takes to browse your network, by editing the following registry entry on the Tutor Console machine.
Open the Registry Editor and navigate to:
HKEY_Current_User\Software\NetSupport Ltd\PCICTL\ConfigList\NetSupport School
Name Lookup Delay
To add a name lookup delay, add the following string value to the key:
The value for this string specifies the delay between broadcast packets in seconds or the amount of time that each scan will wait to receive a response from a Student machine. Use this value in conjunction with name lookup attempts to modify the amount of time spent performing browses. The browse is more likely to miss Students if this value is too small.
You should not specify a value that when multiplied by the name lookup attempts value is less than 4 seconds.
Name Lookup Attempts
To edit the number of name lookup attempts, add the following string value to the key:
The value for this string value specifies the number of name lookup packets broadcasted during a browse or the number of times that a broadcast packet will be sent to your network.
The fewer broadcasts that are sent, the lower the network traffic and the quicker the browse will complete.
This article is advising you to modify the registry, and you do so at your own risk. Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow the steps carefully. For added protection, back up the registry before you modify it.
