Hey Jay,

Thanks for the quick response.

I pinged both servers and they work just fine.  The services you are talking about are the Replistor Server and Control Service services?

There's also a weird part that even though the communication error keeps occurring, I can see that on serverB, the SCAN, MANV, and CHAR files are getting updated but by a day behind.

I can see in the Monitor window, that the Sites and Disk Space traffic lights are yellow.  Would I have to redo the connection from serverA to serverB?

Not sure what EMC backup product you are using, but some general thoughts:

      if the product is a client-server app, then maybe you have network/fw issues preventing you from seeing

      Have you tried to ping the machine name and then the IP address of ?

      Try tho do the same from the Server to the client, and then the client to the server to see if that works.

      if the client-server app needs specific ports open, you can run a "netstat -anbo" to see the status of

      the specific ports

      have you tried stopping/restarting the backup app's services (windows) to see if that helps?

Sorry...we're heading outside my expertise here...network connections and "Replistor Server and Control Service services" are not something I deal with every day.  here's hoping that someone else who sees this post will jump in and be able to give you the next thing to try!
