I am getting a heartbleed vulnerability on a server that has IIS7.5 express. This is actually a domain controller. Is this an actual threat or is this a false alert since microsoft doesn't use Openssl?

What is stating you have the vulnerability? That's an important bit of information.

We are using Saint 8 to do the vulnerability scanning.

A quick search didn't turn anything up on Saint 8, which is concerning.

It may be a false-positive, as suggested. But it may be something to be concerned about.

Specifically, if the tool is an independent service-based scanner, it may be picking up other problems. If you have a reverse proxy or WAF, for example, it may use OpenSSL to scan SSL traffic as part of its proxy duty, even if the final destination is your Microsoft server.

Alternatively, there is a plethora of malware that uses SSL (port 443 is the universal "bypass the firewall" protocol, after all) and quite a bit of it is built on SSL. This could be a subtle indication that the server does indeed have something listening that uses OpenSSL, even if that "something" was not intended.

Or....it could just be a cut-rate scanner (like I said, I could find very little mention of it), and is truly just a false-positive...

Nothing in WIndows or IIS (Express or otherwise) uses OpenSSL...but I wouldn't be too quick to dismiss that specific vulnerability. Considering testing for the exploit usually requires successfully *doing* the exploit, false-positives for heartbleed specifically are rare with most security scans.

Are your corporate email signatures appalling?

Is it scary how unprofessional your email signatures look? Do users create their own terrible designs and give themselves stupid job titles? You can make this a lot easier for yourself by choosing an email signature management solution from Exclaimer today.

If it goes through OpenSSL at any point on the windows server, should I be able to find it in the registry or is there TLS heartbleed software/application i can install to test?

Regarding the registry, not really. Most compiled packages of OpenSSL for windows that I've seen are Cygwin based and don't register in the registry.

Regarding software, there are vulnerability scanners you can install, sure. Plenty. Like antivirus software, pick the one you are comfortable, but everybody else will have a different opinion.

We are currently using Saint vulnerability scanner - but i wanted to see if there was a desktop app to test. AV isn't going to pick up on a heartbleed vulnerability.

As I said, there are many. I was using AV as an analogy that there isn't "just one" and that different people will have different opinions on their favorite. From snort to Secunia to....bing is your friend. As are reviews.
