Browse For Service

Use this dialog to browse for services on the specified device.

Note: Credentials are not necessary if browsing for services on the WhatsUp Gold computer.

• Host name or IP address to list services on. Enter a host name or IP address. WhatsUp will connect to this computer and list all services available on the device.
• User name. Enter a user name to browse for services.
• Password. Enter the password for the user name specified above. To monitor NT services on a XP machine with an account that has empty password, the XP's Local Security Settings might have to be modified. From Administrative tools > Local Security Settings, click on Security Settings > Local Policies > Security Options. Then right click on the setting: Account: Limit local account use of blank passwords to console logon only and click Properties, and select Disable.

Credentials

If a domain account is used, then the expected user name is domain\user. If the device is not member of a domain, use machine name\user.

Permissions

If the credentials entered on the Browse for Service dialog are not correct, and/or don't have the necessary rights, the connection will fail. In order to monitor the service on another machine, the NT Service Monitor must be configured with the correct user name and password and a user account that belongs to the administrators group on the remote machine. WhatsUp Gold highly recommends that you use an account with administrator privileges to browse for services. For more information see THIS Knowledge Base article.

Firewalls

In order to connect to the target computer, TCP port 135 must be open to the target computer. This port is used by the Windows Remote Procedure Call (RPC) Service, which directs Distributed COM (DCOM) traffic from remote computers. WMI uses DCOM to communicate with remote computers.
