This morning I had several users report an error accessing resources on a DFS namespace. I looked at the domain controller this namespace is on, and I am seeing several errors. The first of which, I believe to be the root cause.
Event ID: 3224
Source: NETLOGON
Error:
Changing machine account password for account MACHINE$ failed with the following error:The administrative limit for this request was exceeded.
I've been looking for reasons online, but I can't seem to get anywhere.
This is followed up with other errors with GPO, DFS, some kerberos, WMI, FRSm and VSS.
The kerberos message seems related:
The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server machine$. The target name used was ldap/machine.domain.com. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server. This error can also happen when the target service is using a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC are both updated to use the current password. If the server name is not fully qualified, and the target domain (DOMAIN.COM) is different from the client domain (DOMAIN.COM), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.
I tried to change the password on the server account with Netdom, but I received the same error as above. "The administrative limit for this request was exceeded."
Would appreciate any pointers!
