As you can see this is my first post, apologies if it's the wrong section or repeated info, although I did have a look around.
We've successfully been running FileMaker Server Advanced Console (126.96.36.1999) on a Windows Server 2008 for some time with users on the network using the Admin Console from a Mac OS X (10.6.8) and Windows 7 PC. Both have the latest update of Java, on the mac that is 'Java for Mac OS X 10.6 Update 5'.
I came recently to use the Admin Console from a different Mac (same operating system as above though) and I recieve the 'Admin Server Connection Error' message, then tried this on a different Windows 7 PC and recieved the same error mesage. I then tried to run the Admin Console from my brand new Mac OS X 10.7.2 and it also failed to launch with same error, I don't have any software on it except the updates for Java which is 'Java for Mac OS X 10.7 Update 1'.
The PC and Mac I mentioned initially are still running the admin console fine. There are no restrictions in the FM Server configuration which restrict IP addresses. I should also mention the Mac's in question have FireWalls disabled, so all ports open by default.
Any help would be greatly appreciated.
