I recently downloaded the trial version of ACT! by Sage 2008 (10.0) Version 10.0.2.191. I`ve been using it for a couple of weeks and I`m experiencing freeze ups. I`m using XP Pro SP3 and the event log is filled with mostly informational stuff but also a notice telling me that 'The SQL Network Interface library could not register the SPN (Service Principal Name) for the SQL Server service. Errorx54b state:3 Failure to register an SPN may cause integrated authentication to fall back to NTLM instead of Kerberos' It goes on to say that further action is only required if Kerberos authentication is required by authentication policies. I have no idea if this could be causing a freeze up but it seems to be in the event log after it freezes. Any ideas anybody ? Pleaseeeeeeee !!!
