connection dropouts

any thoughts please on why we are seeing quite regular dropouts every 30 seconds and if there is a fix/workaround for this.
These are enough occasionally for the sentinel software to lose the key and drop the licence out which then inconveniently requires server access to reset.
Server is on a standalone W10 PC with nothing else running on it; client is a virtualised server on VMware; everything else appears rock solid.
VH Client is 5.2.1

#2

2008 is not supported

#3

doh - totally missed that.
Still works (mostly) even if unsupported!
Server's being upgraded soon so this should fix it.

Many thanks for great bit of software.
