title: Replication Monitor: Cannot Connect to Publisher
body: <p>Everything It was working fine for a quite long time period, but suddenly this evening I found that I the replication does not work and I cannot browse the publications in the Replication Monitor</p>
  
  <p>Please have a look at the attached image.

  <p>The publisher at the bottom is OK - attached and working. But the publisher at the top is attached, but for some reason I cannot browse its Publications. When Selecting something the left side is white. As you can see there is a red "x" which means that there is a problem with the connection. </p>
  
  <p>I tried to remove and then to re-add the publisher, but this does not solve the problem. </p>
  
  <p>In Windows Event Logger I found this Error:
  "The transaction log for database 'Distribution' is full due to 'LOG_BACKUP'. " And I'm not quite sure what is this....</p>
  
  <p>Any ideas are welcome
  Regards,</p>
