Hello, nice to meet you. My name is Alex and i'm new in the group. I'm not an expert AD Administrator, but if is there any way that i can help you all, just ask. =) Well... i'm trying to solve a puzzle regarding the ADDS (2008 R2 Std) and ADCS (2008 R2 Enterprise) using the NDES (Network Device Enrollment Service) to integrate it with a Cisco ASA emulator on GNS3. The following picture represents my network lab: windows7-cliente01.corp.local -> Is a client computer of domain corp.local adds.corp.local --> Is a Active Directory Domain Services (DC) for the network. adcs.corp.local --> Is a Active Directory Certificate Services; --> It has a Network Device Enrollment Service installed; My problem with this scenario is that i can't get the NDES to work properly. I've installed the service without problems during the wizard using the following data: --> Username: CORP\Administrador On the next page, i've leave the defaults and continued pressing "Next" and then "Finish" When i open the NDES page, i get a 500 Internal Error from IIS. On "Event Viewer", i got two errors for the NDES and the following ID: ID 8 - The Network Device Enrollment Service cannot retrieve information about the Certification Authority. ID 2 - The Network Device Enrollment Service cannot be started. I copied the codes and i came to this page to translate the code and see a sugestion for the problem... but the resolution page was blank for these two codes - http://technet.microsoft.com/en-us/library/ff955644(v=ws.10).aspx I've tried to uninstall the NDES and reinstall again, but no success. I didn't got errors when removing and installing the NDES. Is there any way i can track down the problem, or raise the debug? Thanks again for the help. =)
