Dear Group, I am facing a piculier problem regarding installing ADC in my domain. I have a domain and i have an ADC also, but the thing is when i want to intall another ADC under my domain. it show an error message-showing a $sign after the name of the host- my host name is PP and when i went to make it ADC it generates the message PP$ cannot access the active directory. Yet i have a plan to install and configure EXCHANGE 2000 in my organization and i am going through a testing a testing phase. please send me and provide me some solution or is there any online solution procedure? with positive expectation i am waiting for your solution:-) --------------------------------- Do you Yahoo!?
