We have two windows 2003 standard server with no service packs on which we have veritas cluster with Veritas Storage foundation HA 4.2. The two servers are in Clutered environment managed by veritas cluster server. The Storage to the servers is provided from SAN. We have a DFS cluster on this setup and a application uses this DFS to open the documents uploaded to the storage. The users who are using this application are constantly reporting that they are unable to view these documents, stating that they see NOT ENOUGH SERVER STORAGE IS AVAILABLE TO PROCESS THIS COMMAND. We checked microsoft support article http://support.microsoft.com/kb/225782/EN-US/ and made the necessary changes but still of no use!! The antivirus software installed on the machines is from ETRUST.
