Hi, We are running NDES in our production environment. All servers are running Windows 2008 R2 SP1. My question is, when NDES role was installed on the SCEP server, we used an NDES service account (account A) to run NDES. Now we want to create a new service account (account B) and use the newly created account to run NDES. We've added the new account in the local IIS_IUSRS group and assigned the same permissions as the previous account. However, when we change the account in IIS, we can't access the scep admin page. Has anyone done this before? Thanks!
