Are you getting some type of pop up error informing you why it isn’t coming up or is it just sitting there when you click on the NetConfig button in the GUI?
Is this a new upgrade to 5.6 or have you been on it for a while?
We have been on it for quit some time…we did just put on the Rev1, but it is only effecting one of us, not all of us. It also is happening on both our test and production servers.
