TCP/IP Fundamentals Guide Released by Microsoft

Early on in my IT Career while working a temporary job as a pc tech I had the fortunate opportunity to take a Microsoft Certification course on TCP/IP.  A coworker of mine had to cancel and as such I recieved this training which was quite expensive at no cost.  I’ve always enjoyed learning and at the time thought it was a cool opportunity but since then have realized how much a simple foundation in networking, TCP/IP, and DNS is a critical part of being a quality technician, engineer, or administrator.   Tonight I came across the Guide: TCP/IP Fundamentals for Microsoft Windows which appears to be a fantastic instructional on networking and TCP/IP.  Check it out and if your new to this enter into it knowing that IP and subnettting is a boring thing but having a solid understanding of it and routing will give you a new understanding of the networks your employed to care for.

IPhone, Exchange, and RapidSSL Certificates

Today I setup my first IPhone on an Exchange Server with Mobile Activesync.  The Exchange setup was nothing special – I enabled HTTPS over RPC using a great article over at Petri.co.il – A Great website to checkout if you haven’t been there.  Next I completed the steps Found on this Apple Information Page for preparing for the IPhone – Again nothing special.  I was then able to test my Exchange setup and send the end user the setup information.  The connection tested fine in outlook but not on the IPhone.  I thought perhaps the IPhone did not have the Equifax certificate needed for the RapidSSL certificate used on the server and after a bit of research found out that correcting this is as easy as emailing the certificate to the phone.

First visit your exchange server using Internet Explorer.  Click the lock next to the address bar (if IE7) and select View Certificates.  Then click install certificate and walk through the wizard.

Next open Internet Options and click “Certificates” on the Content Tab.

Look Under “Other People” for the certificate and After selecting it click “Export”.  Name the certificate something relevant and accept all other defaults.

Once you have your certificate Email it to your Iphone.  This may require you setup a temporary IMAP or POP account with Gmail or elsewhere.  Once you have you email in hand simply open the attachment on the phone and you’ll be prompted to install it.  Once installed setup your Exchange sync as normal.
