I am running 3 NW 6.5 SP6 servers and one has Border Manager 3.6 Sp2a
loaded on it. I installed another NW 6.5 Sp6 server into the system and
now my proxy on my Border Manager server is failing.

My proxy cache screen shows correct until the bottom where it says:
Proxy SSL Listener at all TCP/IP addresses: 443
** Error ** Bind error 48
MiniWeb server at all TCP/IP addresses :1959

What could cause this? Was it the install of the new server in the system?
