cluster error

We have a one node cluster that is receiving the below error messages in the cluster.log and the Event Viewer. In the SQL Server 2005 SP2 job that fails we receive a slighlty different message. The OS is Windows 2003 SP1. This is not a 64-bit box. We have checked the permissions of the cluster service account in SQL Server to be sure they are correct. Can anyone please help with this issue.

I'am having the same issue.|||

Moved to High Availablity forum...

(Please do not 'cluster' bomb so many forums with the same posting. Pick one, and give it time.)

|||What type of server (HP, Dell)?|||Anyone have any Ideas on this. I am having the same problem.
