Hi Deepak,
If you refer to the other thread in this group started by Mitch Galant 2
days ago, you'll see that he's seeing similar problems. He has not been
successful with getting client certificate authentication to work on .NET
1.1 SP1 unless the private key has no strong protection and it is in the
Current User MY store. Putting the key in the machine store doesn't seem to
work.
You guys might want to try to combine forces to try to solve this.
However, if you have success by deploying the HttpWebRequest in COM+ under a
specific identity, I'd suggest you just take that and run with it. I'm not
certain this will get any easier.
