This is my first post on this really great board, so first of all I would like say HELLO.
Now, my problem is.
I have got two Administrator Consoles on one machine to manage two domains.
When I logging to one Admin Console using web browser, logs me out of the other one.
I use the same name and password for both consoles.
Seems you got the solution, anyway here is my blog on the same - http://weblogicserveradministration.blogspot.com/2012/10/opening-multiple-weblogic-console.html, you will lots more important stuff there also.
