Connection Limit ON ISA 2004..


I have monitored several time I got this alert from my ISA 2004 dashboard , and I got the results from MSFT,
ISA Server sets a default value for connection limits, or you can define a custom connection limit for the ISA Server computer. In ISA Server 2004 Enterprise Edition, this custom limit applies to all array members. Then, you specify IP addresses to which this custom limit should apply. A typical IP address assigned a custom limit would be a Web server, which may require many connections, and therefore need an increased limit. Custom IP addresses can be defined using computer sets.

Connection Limit Configuration

There are a number of places to configure connection limits in ISA Server Management:

  • General node. To set this value globally for all types of ISA Server traffic (incoming requests to published servers and outgoing requests from Internal clients), specify connection limit settings in the General node of ISA Server Management. For instructions, see Specify connection limits in Appendix A: Configuring Connection Limits.
  • Web listener. You can specify connection limits for a specific Web listener. Web listeners are used in Web publishing rules, and one Web listener may have multiple rules. When you specify a connection limit on the Web listener, you are limiting the number of connections allowed to Web sites published using the specific listener. For instructions, see Specify connection limits for a Web listener in Appendix A: Configuring Connection Limits.
  • Web proxy on a specific network. You can specify a connection limit on the Web proxy properties of a specific network object. Web Proxy Filter handles outgoing HTTP traffic on port 80. When you specify this connection limit on a specific network, you limit the number of concurrent outgoing Web connections that are allowed on a specific network at any specific time. For instructions, see Specify Web proxy connection limits for a network in Appendix A: Configuring Connection Limits.

ISA Server alert: Event ID: 14147

This issue occurs if the ISA Server or Microsoft Forefront Threat Management Gateway, Medium Business Edition network objects do not match the routing table entries that ISA Server uses to understand the network topology. Event ID 14147 may be logged when you first create a remote site network when you configure a site-to-site VPN connection in ISA Server. ISA Server requires that only one network adapter is associated with a single ISA Server network, and that network adapter IP addresses are not configured in more than one network. IP address ranges must be configured correctly for ISA Server network objects, and match the routing table. Network object definitions should include all remote subnets that can be reached through the adapter that is associated with the network. Additionally, persistent static routes should be defined in the routing table for each remote subnet. On the computer that is running Microsoft Internet Security and Acceleration (ISA) Server, Microsoft Forefront T...

.NET Vs PHP

I am in bit confusing about choosing the correct language for a new project ( Focused on bulk e-mail handling) Feature .Net PHP Compiled Code – Increases website speed (precompiled is the fastest) Yes – both precompiled and dynamically compiled when a page is requested No – a 3 rd party accelerator can be used to increase performance but it is not installed on most shared hosting servers. Scripted Language – results in poor website performance No Yes – a 3 rd party accelerator can be used to increase performance but it is not installed on most shared hosting servers. Object Oriented – Increases the ability for code reuse and provides enhanced features as well as reduced development time; since code is more reusable, results in fewer bugs that can be discovered by any client and fixed for everyone; encourages developers to write more maintainable code. Yes No Supported Development Languages – easier to find developers C++, C#, Visual Basic.NET, Jscript.NET, Python, Perl, Java (J#),...
