Oh, that's good to know, because all of our routers, switches and VPN 
concentrators are Cisco.

I installed the update from Microsoft, and now works fine on IIS.

I had this same problem. In addition to unsupported hashing algorithm, I think 
it also indicates a key size that is too large. I had to select a 2048 key for 
other reasons (cisco scep).

Actually I used SHA1. Here's the fingerprint:
SHA1:9B:5E:2D:34:99:4A:E7:0E:55:3D:C6:30:A9:8E:A4:81:43:BB:57:0A

The warning signs simply indicate that these extensions are critical -
this is expected behavior
W2K3 SP2 probably does not have support for the SHA2 hash algorithms (I
think you need at least SP3) and I am guessing you used a SHA2 hash when
you created your certificate.
Either go back and use SHA1 or MD5 (not recommended), or update to SP3
