count of currently opened files?

[info]

Greetings,

I am getting "java.io.FileNotFoundException:<various file
names> (Too many open files)" error messages on a Win2000
server running IIS and JRUN to support a web-based app.

I think this message may mean that the web app is not
closing sockets or files properly. I want to try to
track that down and had a couple of questions to help me
formulate a testing plan. I _think_ the max files
capability of the OS is being reached, since the
JRUN tier here seems to be set with no limit.

1) For Windows 2000 SP3, what is the max open files
that can be supported by default?

2) With no FILES= config.sys type parameter any more,
how would one change the default (thinking of a
higher value temporarily while I track this down)

3) Is there anywhere in Windows 2000 that I can
check to see how many open files a process or
service currently holds open?

Any advice here would be greatly appreciated. Thanks.
