when the firewall is down it connects straight away.
the question I would like to address is:
is it always these
number below (29237 and 26244) that sql server uses for connection?
I am aware of the port numbers on single and multiple instances.
This server by the way is not a named instances.
initialization =29237; handshake=26244
or does it change? if so then - based on what?
we have had issues with one domain controller but I have ruled that out.
