Event IDs 1030 and 1058 on Server 2003 Domain Controller
Written by Sam McGeownI logged onto a production domain controller this morning and checked the event logs to be confronted with this:
Event ID 1030 and 1058 every 5 minutes, looking into the detail for these events I can see its a replication issue for one of the GPOs.

There was no visible cause for the errors, DFS had just got it’s knickers in a twist somehow and was not resolving the DFS share for the domain correctly.
The resolution was fairly simple, running the “dfsutil /purgeMUPCache” command seems to have resolved it for now. The /PurgeMUPCache command clears the MUP Cache (duh!) which holds info about DFS and other shares on the client system.
Technet says: “Clears the client MUP cache, preventing confusion about the current provider when such names conflict. Except for a temporary performance hit, this command has no other adverse effects. This command does not affect any DFS metadata. If this command is not run, and the namespace is not accessed, the obsolete cache entry eventually expires.”
There are plenty of other causes for these errors, if your server is multi-homed (multiple NICs) then check that your “public” NIC is at the top of the adaptor bindings.
My DC is now running happily, no 1030 or 1058s.
