Running Exchange 2010 on public IPv4 and IPv6…

Sunday, November 21st, 2010

Yey! Today I have put a testing Exchange 2010 online to make my “exam” on Hurricane Electric IPv6 certification program… Well what I did is to put two extra DNS records to my DNS one with IPv4 “A” record pointing mail.ipv6.testingdomain.com to some IPv4 address and another “AAAA” record pointing mail.ipv6.testingdomain.com to an IPv6 address where my Exchange 2010 is listening…
Then I have added an MX record for domain ipv6.testingdomain.com to point on mail.ipv6.testingdomain.com.
Great! Everything works? NOT! :)

If you want your Exchange 2010 to receive mail from IPv6 mail servers you need to configure your receive (and send) connector to listen on IPv6 address of your server…

 Let’s configure Internet receive connector that is listening on fqdn in my example mail.ipv6.testingdomain.com First you need to add IPv6 address on which your server is listening on…

 

By default your server will accept only traffic from IPv4 world so we need to add IPv6 range…

 

 Let’s do it…

 

 Here goes the tricky part… If you think about an IPv6 address you always thing about 8×16 bit separated by colon… And logical solution would be to insert beging of range 0000:0000:0000:0000:0000:0000:0000:0000 and the same for FFFF:FFFF:FFFF… eight times… But no… You need to replace last two segments of 16 bits with 32-bit IPv4 represntation… So you need to insert:

Windows Phone 7 – Active Sync issue… 80072F06 when using self-signed certificate

Friday, November 19th, 2010

I am a proud owner of a brand new Windows phone 7 (running on Samsung Omnia…)! :) As soon as I did unpacked my phone I wanted to sync it with my Exchange server… I am using a self-signed certificate and first I had to install the certificate… Ok, you have two options here… You can go to https://mail.domain.com/certsrv and install a certificate directly from your certification authority or somehow put it on your phone by sending it to your email that you can access using web browser on Windows Phone 7…

Ok… To this step everything fine… But now I want to sync and I receive an error saying…

There is a problem with the certificate for mail.domain.com. Contact a support person or your service provider. Error Code: 80072F06

Hmm.. I tried to open my Outlook web access using web browser on my Windows Phone 7 and it worked without any problem – no certificate error warning… So I was realy confused now… My certificate is installed and I do not get any error what the hell is wrong with Active Sync now?

Well… You need to “reboot” your phone and everyting will start to work :)

So press the power button and hold it for a few seconds until you receive a “Goodbye” on phone screen… After turning it back I tried to sync again and TADA! Everything is working now!

Peace and love,
