I've had the same issue, below is my information...
- Windows 2008 Web Server 64-bit Edition
- IIS7
- SQL 2005 Express
- Network Solutions Basic SSL certificate
Each time I try to complete the certificate request I get the following error...
CertEnroll::CX509Enrollment::p_InstallResponse: ASN1 bad tag value met. 0x8009310b (ASN: 267)
I should also mention that I have already added the 3 other certificates provided by NetworkSolutions under the Certificates snap-in. When I open up IIS I do not see my certificate request listed however IIS knows that it's there so I'm not sure if I should see it listed or not. Under "Certificates -> Certificate Enrollment Requests -> Certificates" I can see the pending request. Up until a few minutes ago I had several listed there and have since cleared/deleted them out and re-requested the certificate from NetworkSolutions although I don't have any faith this will work. There were several from past failed attempts. Should I be able to see the certificate request in IIS7 after creating the initial request before it's completed? My server doesn't do much other than host a few websites and run SQL 2005 Express. I know some have said something about SQL but I can't imagine what that has to do with my situation since I simply want to add an SSL certificate to IIS7 to run a single website with SSL encryption.
Is it just me or should this not be ridiculously simple to accomplish and yet it's been the single most frustrating thing I had to do in a great long while. NetworkSolutions doesn't have any answers, Microsoft wants to charge me an arm and leg just to say "Hi", and I'm losing my patience with the whole thing since it should literally take less than 5 minutes to complete a simple certificate request.
Does anyone out there have a solution to this problem because I'm Googled out...
Thanks in advance for any support provided,
Matt
