I am trying to establish an SSL connection to our company's LDAP server from
an ASP.NET application running on Windows 2003 Server and I am getting the
following set of event log errors:
Event Type: Error
Event Source: Schannel
Event Category: None

policy settings.
Event Type: Information
Event Source: Schannel
Event Category: None
Event ID: 36880
Date: 10/21/2004
Time: 8:36:21 AM
User: N/A
Computer: R1E3S1-BL40P
Description:
An SSL client handshake completed successfully. The negotiated cryptographic
parameters are as follows.
Protocol: TLS (SSL 3.1)
Cipher: RC4
Cipher strength: 128
MAC: MD5
Exchange: RSA
Exchange strength: 1024
All of this works fine from a Windows 2000 Server, so I am trying to figure
out if there is some difference between the 2, or if there is an extra
configuration step needed under 2003. On both systems, I have our corporate
root certificate installed as a Trusted Root Certificate, and a server
certificate installed for IIS.
If anyone has a suggestion of what to try, I would greatly appreciate it.
Thank you,
Clark Laughlin
