I have an SBS 2003 domain with a Windows 2003 domain controller and an SBS 2011E controller with the FSMO roles. The Clients are all Windows 7.
One Windows 7 clients gets the following message when trying to access mapped drives:
The system detected a possible attempt to compromise security. Please ensure that you can connect to the server that authenticated you. This computer also logs the following event ids:
1053 The processing of Group Policy failed. Windows could not resolve the user name.
40960 The security system detected an authentication error for the server cifs/xxxxxx. The failure code from authentication protocol Kerberos was (0x80080341).
Also, this user cannot ping computer names, only IP addresses.
The Windows server 2003 logs the following error:
27: While processing a TGS request for the target server krbtgt/CGA.LOCAL, the account Cxxxxxx did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 8). The requested etypes were 18. The accounts available etypes were 23 -133 -128 3 1.
I am having no luck connecting the dots using the web.
Please help if you know what is going on.
