TMG 2010 Service Pack 2
Server 2008 R2 Service Pack 1
Only one member in the array
I have enabled "Use customized HTML forms instead of the default" in a listener. That works fine, as long as I stick to the original custom folder: "ISA".
But once I make a copy of the default folder, calling it "ISA-2" and try to use that copy, the error is
Error Code: 500 Internal Server Error. The data area passed to a system call is too small. (122)
As far as I can see, the copy - ISA-2 - is a perfect copy of the original - ISA. (The error message is the same as the one I get if I specify a folder that does not exist at all.)
