Cause

If not all ports on the Enterprise Vault (EV) server are open, communication to storage and indexes will be limited and cause 7116 errors during archiving and expiry.  This limitation will also cause EVSVR repair operations to fail on the majority of the data set being processed.

Solution

1.  Verify the current port range by typing the following in a command prompt on the EV server:

netsh int ipv4 show dynamicport tcp

2.  If the port range is not as follows, then it will need to be increased: 3.  Update the port range with the following example:

netsh int ipv4 set dynamicport tcp start=1025 num=64510

4.  Restart the EV Storage and Indexing services.  (Note: A restart of the server is not necessary when changing the port range.)
