Re: Open Ports on an Exchange 2000 on Server 2000

Hi,

Most of these services are expected to run on Exchange server. If not used,
you can stop some of these services (e.g. you can stop pop3 or pop3s or nntp
if these services are not used in your environment.

Some of the services that do stand out are running on TCP ports above 1024
e.g.
- 8081/tcp open blackice-icecap
- 38292/tcp open landesk-cba
and few others.

Check what is actually running on these TCP ports. You can e.g. use TCPView
tool from www.sysinternals.com. It will tell you what process is using these
ports... Once identified, make sure that there are only services that you
install and need on the server. If you did not install them check your
server and try to determine how they got there.
