Hi David. Thanks so much for responding. I'm trying to write a
Credential Manager using the Network Provider setup.(ref:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/security/security/implementing_a_credential_manager.asp)
 According to the link provided it seems that Win2K is supported. Am
I reading this incorrectly?
