TMG 2010 is logging an error “Failed Connection Attempt” Status: 64 The specified network name is no longer available”
Tuesday, June 14th, 2011
Working with a client on an Exchange 2003 to Exchange 2010 migration and had some issues with Outlook Anywhere working. I did some digging and resolve the issue as being something stupid I had done with the TMG 2010 rules. However along the way I found this particular error occurring at times and for a short while it lead me on a wild goose chase.
I eventually through the power of google, found this article here explained it all to me. Long story short – it’s by design, but the author of the article did even more digging that explains exactly why it’s by design.

How to access Windows Activation Server through ISA or TMG Firewalls
Friday, December 10th, 2010
Today I had to create a rule in ISA/TMG for a client to allow any computer to get out to the Windows Activation Servers without the user being given access to other websites. It was pretty simple but I thought I’d share with you all.
Basically all the rule has to do is to allow HTTP and HTTPS protocols out from All Protected Networks to 64.4.11.160 (this is a referrer server that MS use to direct it to another country/locality based activation server) and create both a Domain Name Set and a URL set for *.microsoft.com. I could have gone more precise with the *.microsoft.com but that might then break things in future if the activation servers change based on the referral server.
The rule looks like this.
Build the rule, apply it – wait a few minutes for TMG’s configuration to sync with the TMG Configuration Database and you should be good
