URGENT - Replication Issues - Help needed!!

[PaddyT]

I am getting the following error message in event viewer:

Event Type: Error
Event Source: NTDS Replication
Event Category: Replication
Event ID: 1084
Date: 18/01/2007
Time: 10:54:06
User: NT AUTHORITY\ANONYMOUS LOGON
Computer: MAINSVR
Description:
Internal event: Active Directory could not update the following object with changes received from the following source domain controller. This is because an error occurred during the application of the changes to Active Directory on the domain controller.

Object:
CN=UserNamehere,OU=Staff,DC=XXXXXXX,DC=int
Object GUID:
d0a5ab07-0c34-4853-bd87-a17dd2c38dd0
Source domain controller:
dbc20614-265c-47cb-965e-c59edde9b654._msdcs.xxxxxxxx.int

Synchronization of the local domain controller with the source domain controller is blocked until this update problem is corrected.

This operation will be tried again at the next scheduled replication.

User Action
Restart the local domain controller if this condition appears to be related to low system resources (for example, low physical or virtual memory).

Additional Data
Error value:
1127 While accessing the hard disk, a disk operation failed even after retries.



I have tried to delete the object, but get the following message:

'Windows cannot delete the object because an internal error occured'

Any help would be greatly received!

what if you go to ADSIEDIT.msc and try to delete the user from there?



Thanks,
