Hi all, I am facing a peculiar problem. After installing ISA and joining it to an array, "ISA Server Control Service" fails and gives out the following errors on the event log. I have tried again and again, rebuilt the servers number of times with the same results. Any help would be appreciated. Thanks Raminder Microsoft ISA Server Control failed.
