I am using Windows Server 2003. I am confused about the available
(memory) value under Physical Memory category.

From search there are two meanings,

1. available means free physical memory, not used yet by any
application;
2. available means the total size of physical memory user application
could use (exclude System Cache and Kernel Memory, which user
application can not use), the user application may actually already
used some of them, and they are not *all* free.

(2) is from http://articles.techrepublic.com.com/5100-6346_11-5071997.html

--------------------
Since you know that at this point the operating system is making 208
MB of physical memory available to running programs and that the Total
is 243 MB, you can come up with a rough estimate of the actual size of
the page file by subtracting the Total Commit Charge from the
Available Physical Memory. In this case, you end up with 35 MB.
--------------------

My question is, which one do you think is correct? :-)

As you might guess from the mention of "detail", simple answers to this
question are either incorrect or impossible to understand without quite  
a bit of knowledge about the details of Windows.
