Saratoga, CA, April 4th, 2003

Castle Rock Computing, a leading supplier of Network Management software for Windows, today announced the release of SNMPc 6.0, the latest version of its leading network management system.

New Features for Management Service Providers
SNMPc 6.0 addresses a Management Service Providers (MSP) need to manage multiple customer networks with overlapping private IP address ranges from a single server.

“The distributed polling technology of SNMPc Enterprise 6.0 allows an MSP to use one server to manage multiple customer networks even if those customers are using the same IP address ranges,” explained VP Sales John Maytum. “Customers are provided with a secure login to view their own network status and trend reports. By managing multiple customers from a single server an MSP can realize considerable cost savings and reduce network complexity”

Unattended Server Operation
SNMPc Enterprise 6.0 now operates as a Windows Service for improved security and operational reliability. This provides the ability for SNMPc to run in a secure unattended server location. Users without proper authorization cannot stop or control management services. In the event of an expected system reboot management services are automatically restarted.

Improved Management for Routers, Switches, Servers and Cisco Devices
SNMPc’s management menu system has been redesigned for improved ease of use and support of additional devices. SNMPc 6.0 includes management for Windows and Unix Servers monitoring key variables such as CPU and Disk Space. Statistics can be monitored in real time or as part of a long-term trending analysis. Thresholds can be set so network administrators are notified by email or pager when problems occur. Other new additions to the menu system include Cisco performance metrics.

Sean Wachob, VP Engineering, explained “We have been working closely with customers to identify the key metrics they need to manage their network infrastructure. Our new menu system reflects those findings and delivers to customers the most efficient way of managing devices such as Routers, Switches, Servers and Cable Modems”.
