title: Merge replication 'A Security error occurred'
body: <p>I have a merge replication configured with a publication and a distributor ruining on the same machine- SQL Server 2012 and Windows server 2008. The replication used to work fine for the past 4 months. But now when I open the monitoring window to check the status, it says "A Security error occurred" on all three subscribers and now it is not replicating.</p>
  
  <p>Thank you in advance</p>
