Microsoft Exchange TCP/IP Ports List

This is just going to be a list of all the TCP & UDP IP ports that you could possibly need to use (or open in your firewall(s)).

TCP port 25 - SMTP
TCP port 26 - SSL secured SMTP
TCP port 110 - Post Office Protocol v. 3 (POP3)
TCP port 995 - SSL secured POP3
TCP port 143 - Internet Message Access Protocol v. 4 (IMAP4)
TCP port 993 - SSL secured IMAP4
TCP port 80 - HTTP for Outlook Web Access
TCP port 443 - SSL secured HTTP for Outlook Web Access (HTTPS)
TCP/UDP port 389 - Lightweight Directory Access Protocol (LDAP)
TCP port 3268 - LDAP communications with an Active Directory Global Catalog Server
TCP port 119 - Network News Transfer Protocol (NNTP)
TCP port 563 - SSL secured NNTP
TCP port 135 - Remote Procedure Protocol (RPC) however it will also use ports 1024 and up as needed.
TCP/UDP port 53 - Domain Name System (DNS)
TCP port 102 - Mail Transfer Agent (MTA) *Only used in X.400 connections.
Additionally if you are secureing any servers such as front-end / back-end servers with IPSEC you will need to allow IP protocol 51 for the Authenitcation Header, IP protocol 50, TCP/UDP port 88 for KERBEROS, and UDP port 500 for Key Exchanges.

That's a pretty decent sized list "JUST" for one network service. On the plus side most of those are not needed in a default setup as POP3 and IMAP4 are rarely used in a pure Microsoft network.

Also hopefully this will help me remember some of the less used ports and let me ace my test!

-EDIT: Thanks to the commenter I updated this post to have the correct Global Catalog server port.

Follow up to Safari for Windows!

To be blunt, I am already un-installing this piece of software (POS). The two biggest keyboard shortcuts I use don't work. It may be faster at rendering, but our website looks bad in it. If I had to use a Mac or run Linux, I would be using Firefox for sure. On Windows however I am still sticking by Internet Explorer 7.

The install process went smooth, just the standard Next, Next, Next, Finish sort of thing. Let me know what you think if you have had the unfortunate time with Safari as I have.

Safari for Windows!

Apple has released their Safari web browser for Windows. I haven't had a chance to install it yet but I will report back on how the install went and my first impressions.

How to Delete the Undeletable File!

There comes a point in every Network Admins life that you must delete a file that is always locked, even those pesky files that won't go away after a reboot or going into safe mode.

Geeks are Sexy has a good article on how to delete pesky undeletable files. I already knew about #1. I always first try to kill "Explorer.exe" from task manager before I do anything drastic. If that doesn't work I move on to number three if I have Unlocker handy.

I typically have either unlocker installed or an Internet connection to download a copy so I have never had to resort to using the Recovery Console on my computer. Also it is far more likely that I would have those then a Windows CD around to use the recovery console as I always forget to install it before hand.

Microsoft Settles TestKing Case

Microsoft has settled their suit with leading "braindump" site This will hopefully be the start of other braindumps going down as well. For those of you that don't know, or haven't taken a certification test, you must agree to a Non-Disclosure Agreement (NDA) to not discuss or disseminate the material in any way out side of the testing room. This is to protect the value of the certifications. Read more about the settlement here.
