Oracle connections where username has $?

Question

I need help tracking something, I get a few connections where the Enterprise Manager says:

OS User Name: Example$ <-- Example is the machine name.
Terminal: Example
Machine: Domain\Example

There is no user named Example $, where does this come from? ....

I am using Oracle 11g.

Edit: The problem I'm tracking is an asp.net application that supports open connections, I use the "using" statement every time I open them so that it doesn't. It seems that the problem is with the connection pool.

Answer 1

MachineName $ is a machine’s network service account named MachineName, as shown on another machine.
