Management Agent error during Sync

Hi all,
during Delta Sync operation where I synchronize AD contacts from remote forest I receive this error:

System.Security.SecurityException: The source was not found, but some or all event logs could not be searched. To create the source, you need permission to read all event logs to make sure that the new source name is unique. Inaccessible logs: Security.

The Zone of the assembly that failed was:

MyComputer - ERROR UNKNOWN

I've tryed to search for resolution but I haven't found any usefull notice to solve the issue.

Do you have any suggestion to resolve it?
