Tom and Kevin,
Thank you for your quick reply. I am not allowed to uninstall anti virus software on this system but can configure the required exclusions. Anti Virus software being used is Symantec. Do any of the problems I am facing are fixed in a recent release so that I can upgrade to that release? Yesterday night while I was working on this system, I discovered that a Windows Junction Point was configured. Are there any known issues when a windows junction point is configured to the Postgres folder?
