Cryptograhic service provider failed

[netdev]

I have an asp.net application that is using forms
authentication and the encrypt/decrypt methods to encrypt
the ticket. My application works perfectly on my test
system. However, when moved over to production, I am
receiving the following error:
System.Security.Cryptography.CryptographicException:
Cryptographic service provider (CSP) could not be found
for this algorithm


Searching has only revealed one other issue similar to
this with a user using TripleDES encryption. The
suggested resolution was to make sure that the high
encryption pack was installed on the win2k server. I have
confirmed that the high-encryption pack is installed on
our production server. Anyone have any other ideas? TIA.

I have the same problem in certain circumstances. I would be very grateful
if someone could explain me the reason for this.

Meanwhile you could try the following:

1. Set Impersonate to false in your Web.Config
if this doesn't help, additionaly:
2. Configure .NET framework to run under System-Account

That helped solving the problem on my system,

best regards
