On multiple clients running XP, SP3 client I receive this error in event viewer (screen shot attached)
Category: SPNEGO (negotiation)
Event ID: 40961
The Security System could not establish a secured connection with the server ldap/DOHERTY-S1.doherty.lo
L. No authentication protocol was available.
I can logon to the domain fine. I can access some of my mapped drives OK. However, other mapped drives or shared folders on server are not accessible.
All permissions on server are correct and have not been changed. My current setup has been working for years and I haven't changed anything that I'm aware of.
Microsoft has a hotfix for SP2, but all clients are on SP3
I have tried:
Resetting user password
Giving user Domain Admin privileges
Creating new shared folders with same name
Removing computer from domain and rejoining
My server is Server 2003. I have Desktop Authority Installed (has always been installed)
Only recent change: Migrated from local exchange server to Google Apps
