The Microsoft ISA Server Control service terminated with the following error: The specified directory service attribute or value does not exist. This is the error message. Dyrectory Service Attribute it seems to be something from AD, and it is from AD because as stand alone it works perfectly, only as ARRAY do not want to work and this is because in array the configuration it is held into AD. Can anyone, clever enough to help me comparing ALL what it is inside AD related with ISA from my AD with hsi AD to find the difrence ? Please guy. If you ever intented to help me now it is the best time. Right now I'm going to sleep since it was a long day but over 9 hours I will be back online ready for work with some of you.
