    Hi Mark,

    Its fixed! 

    Two things look like being the cause.

    At our site we have the MTU set to 1300. These two appliances were set to 1500. Lesson learnt, always keep looking at network issues :)

    The other odd thing is that both these appliances had a missing replication_host entry when running nbemmcmd -listhosts

    nbemmcmd -addhost -machinename ******** -machinetype replication_host fixed this but it was odd why it was missing on both appliances?

    Not until both these issues were fixed that it sprang to life :)

    Thanks for your help as always
