I am having a hard time Replicating a site in AD. It gives me an "Access Denied" error when I run Replmon. I also did a DCDIAG test and got these results. The site is called Woburn. Any insight would be huge. C:\Program Files\Support Tools>dcdiag Domain Controller Diagnosis Performing initial setup: Done gathering initial info.
