Why is my ISA Server using 50 percent of available memory for the RAM proxy cache?

A. By default, Internet Security and Acceleration (ISA) Server 2000 uses 50 percent of the available memory for a RAM-based proxy cache. To modify the amount ISA Server uses, perform the following steps:

  1. Start the Microsoft Management Console (MMC) ISA Server Admin snap-in (Start, Programs, Microsoft ISA Server, ISA Management).
  2. Right-click the Cache Configuration branch, and select Properties.
  3. Select the Advanced tab.
  4. For "Percentage of free memory to use for caching," change the number from 50 (the default) to the value you want (e.g., 5).
